Jacchia SMITHSONIAN INSTITUTION Washington, D.C. 1965 Publications of the Astrophysical Observatory This series, Smithsonian Contributions to Astrophysics, was inaugurated in 1956 to provide a proper communication for the results of research con- ducted at the Astrophysical Observatory of the Smithsonian Institution. Its purpose is the "increase and diffusion of knowledge" in the field of astro- physics, with particular emphasis on problems of the sun, the earth, and the solar system. Its pages are open to a limited number of papers by other investigators with whom we have common interests. Another series is Annals of the Astrophysical Observatory. It was started in 1900 by the Observatory's first director, Samuel P. Langley, and has been published about every 10 years since that date. These quarto volumes, some of which are still available, record the history of the Observatory's researches and activities. Many technical papers and volumes emanating from the Astrophysical Observatory have appeared in the Smithsonian Miscellaneous Collections. Among these are Smithsonian Physical Tables, Smithsonian Meteorological Tables, and World Weather Records.

Jacchia 2 1. Static and time-dependent models The first multitemperature models of the atmos- phere above 120 km. based on diffusion equilib- rium were produced by Nicolet (1961, 1963). These models proceed from a fixed set of bound- ary conditions, temperature and partial den- sities, at 120 km. Above this height the partial densities vary according to diffusion theory, except for hydrogen for which diffusion equi- librium is reached only at greater heights (Kockarts and Nicolet, 1962, 1963); thermal diffusion is taken into account for helium. The vertical temperature distribution is computed for the "hottest" model, i.e., the one with the highest exospheric temperature, assuming thermal equilibrium; the other models are obtained from this model by conduction cooling of the atmosphere in the absence of external energy sources. The temperatures which are obtained in this manner at the height of 150 km. (a nearly isopycnic layer) are linearly con- nected with the constant temperature at 120 km. Models can be computed by this pro- cedure for conveniently spaced values of the exospheric temperature. These quasistatic models have proved very practical as a back- ground for deriving and analyzing atmospheric 1 This work was supported in part by grant NsG 87-60 of the National Aeronautics and Space Admin- istration. A preprint of this paper has appeared as Smithsonian Astrophysical Observatory Special Report No. 170. Owing to an imperfection in the numerical- integration program, table 1 in that publication is affected by a small systematic error, whose maximum value, 0.011 in log p, occurs at a height around 200 km. when T„ is large. For normal satellite heights and temperatures the error amounts to only 0.006 in log p, so its practical effect can be considered to be negligible. 2 Physicist, Smithsonian Astrophysical Observatory. densities from satellite drag (Jacchia and Slowey, 1963). Atmospheric models can be constructed only at the expense of oversimplifications. Such are, for example, the invariance of the boundary conditions at 120 km. and the constant tempera- ture gradient between 120 and 150 km. found in Nicolet's models. Another serious limitation is the assumption of static equilibrium in an atmosphere which is subject to large day-to- night temperature variations, with a period which is not much longer than conduction time in the lower thermosphere. Atmospheric models which attempt to take into account the diurnal variation at low lati- tudes have been computed by Harris and Priester (1962a, 1962b). They also assumed fixed boundary conditions at 120 km. and dif- fusion above this height, but the hydrostatic equation and the heat-conduction equation were integrated simultaneously and the heat input varied with a 24 hour cycle. Since the amount of solar EUV necessary to maintain the heat balance gave diurnal density oscilla- tions much in excess of those observed, Harris and Priester (1962 a, b) were obliged to intro- duce a second source of heat with a maximum at a different hour. This device may perhaps have a counterpart in the actual heating process, but doubts have been voiced that it may mostly re fleet the inadequacy of an oversimplified theory. By suitably varying the "second heat source," the Harris-Priester models can be made to fit the densities from satellite drag with almost any degree of accuracy, and their new version, pre- pared for the new C'OSPAR International Reference Atmosphere (CTRA 1965) to be published shortly, is remarkably successful in thii: respect. 215 216 SMITHSONIAN CONTRIBUTIONS TO ASTROPHYSICS To analyze or predict the motion of satellites under the influence of drag, one requires models which represent atmospheric variations above all points of the globe in a continuous manner. For this purpose, models of the Nicolet type have a considerable advantage over those of Harris and Priester, because with a suitable model for the geographic temperature distribu- tion above the thermopause they can yield atmospheric densities at any given location and height. The Harris-Priester model is confined to low latitudes and does not account for the seasonal migrations of the diurnal bulge; its extension to higher latitudes would engender gross errors and even a discontinuity at the poles. For this reason, it was deemed advisable to produce a set of atmospheric models pat- terned after those of Nicolet, but based on the most recent data on composition at the bound- ary level and density at satellite heights. The result is the present tables. 2. Boundary conditions The boundary conditions selected for the CIRA 1964 tables are the result of a careful weighing of recent data from instrumented rockets and satellites, and it would be difficult to improve on them at this date. Therefore, we have taken them as the basis for our tables with only one change, namely, the helium concentration which was increased by 40 percent to account for the densities derived from satellites at heights greater than 600 km. at times of low solar activity. There is a distinct possibility that these densities, using a constant value, C D =2.2, of the drag coefficient, are actually overestimated by some 10 to 15 percent, since the drag coefficient should in- crease as the molecular weight of the atmos- pheric gas decreases (Izakov, 1965; Cook, 1965). In such case the excess helium required to account for these densities could be somewhat reduced. At £=120 km. r=355° K, n(N 2 )=4.0X10 n , n(O 2 ) = 7.5X10 10 , n(O) = 7.6X10 10 , n(He) = 3.4X10 7 . Argon was neglected since its contribution to the total density is only 1 percent at 120 km. and becomes rapidly negligible at greater heights. For hydrogen we have followed Kockarts and Nicolet (1962) and fitted the following equation log 10 7i(H) 500 = 73.13-39.40 log 10 T a + 5.5 (log 10 T„Y (1) to their concentrations at 500 km., which were used as boundary for the computation of con- centrations at greater heights. Starting from the boundary conditions, the concentrations n t of each constituent i were computed as a function of the geometric height z by integrating the diffusion equation dn t dz dT ,, , . (2) Here, T is the temperature, a the thermal-dif- fusion factor, and H, is the scale height of the individual constituent, defined as H r - kT ; ~m t g (3) where k is the Boltzmann constant, m t the molecular (or atomic) mass of the constituent, and g the acceleration of gravity. For helium, following Nicolet, we used a = — 0.38; for N 2 , 2 , and O, a = 0. 3. Temperature profiles To compute the vertical distribution of tem- perature on the basis of theory alone, we must know, among many other things, how the heating-energy input varies with height. Since solar EUV is radiated in a discrete number of spectral lines, each of which is absorbed at a different height (Hinteregger, 1962) and each of which varies in intensity with time in a different manner (Purcell et al., 1964), the prob- lem is complicated enough even when we ignore energy sources other than solar EUV. As to temperature and density observations, the lower thermosphere, from 100 to 150 km., is practically terra incognita (or, rather, aer incognitus). Any present-day atmospheric model must introduce a considerable degree of empiricism in constructing temperature profiles in that region; this is also the case of Nicolet's profiles. Since an inadequate theory may be worse than none when it must fit a great many ac- curate observations, as is our case, we decided STATIC DIFFUSION MODELS OF THE UPPER ATMOSPHERE 217 to abandon theory entirely in constructing our temperature profiles. A survey of Nicolet's and of the Harris-Priester temperature profiles showed at once that they can all be represented, with a remarkable degree of approximation, by exponential curves of the form T=T a ~(T a -T 12 o) exp [-s( 2 -120)], (4) where Tn is the temperature at 120 km. and T„ the asymptotic (exospheric) temperature; 04 03 02 01 500° \ 1 3 2a ~2b~^ — 1000° 1500° 2000° T a Figure 1. — The coefficient s of equation (4), which determines the vertical temperature distribution, as a function of the exospheric temperature Too. Curve 1 gives the tempera- ture profiles of Nicolet's (1961) models. Curves 2a and 2b are those pertaining to the Harris-Priester models in the COSPAR International Reference Atmosphere 1965 (2a for 4 a.m., 2b for 2 p.m.). Curve 3 gives the temperature profiles of the present tables. z is expressed in kilometers and s is a constant different for each profile. If we decide to use equation (4) to represent our temperature profiles, the problem is reduced to finding the value of s appropriate to each value of T„, or, better, an analytical expression for s(T„) which will generate temperature profiles capable of reproducing the observed variations of density with height for any stage of solar activity. For example, Nicolet's (1961) densities are reproduced within a few percent with tem- perature profiles generated by equation (4), with s=34.5867 , o ; I -4.414X10- 3 +5.714X10- 7 7 , eo (1000°<7' 0O <2000°). After a considerable amount of trial-and- error work, we found that the densities derived from satellite drag (Jacchia and Slowey, 1963, plus up-to-date unpublished data) can be satisfactorily represented using temperature profiles generated by the equation =0.0291 exp (-tt) r.-soo = 750+1.722X10- 4 (T =12°, 7= +45°. e. Variation with geomagnetic activity. — After the publication of Jacchia (1964), it was found that the relation between the exospheric tem- perature and the 3 hour geomagnetic index a v shows a strong departure from linearity for small values of a v (Jacchia and Slowey, 1964a). The formula given in the last reference can be used without alterations. The increase of temperature with a v is then AT=1°.0 a p +125° [1-exp (-0.08 a„)].

There is evidence that AT/a p is somewhat larger in high geo- magnetic latitudes (Jacchia and Slowey, 1964c). 6. Limitations of the present models As we stated in section 1, atmospheric models must suffer from the oversimplified assumptions one is obliged to make to construct them. Our models share with those of Nicolet the limita- tions imposed by the invariance of the tempera- ture profiles and of the boundary conditions; this latter limitation is common also to the Harris-Priester models. A consequence of the fixed boundary condi- tions is a nearly isopycnic layer at 200 km. at times of moderate to high solar activity. At such times, according to the models (ours, Nicolet's, and the Harris-Priester models), the density at 200 km. should not show appreciable variations when the exospheric temperature varies. This condition is nearly fulfilled by the diurnal variation which practically disappears at heights lower than 200 km. On the other hand, density variations at the 200 km. level have been observed at times of high solar activity in correspondence with geomagnetic storms, and also of the erratic ("27 day") component of the 10.7 cm. flux (Jacchia, 1959). The different response of the density at 200 km. to different types of heating could be ex- plained by assuming that the temperature at 120 km. is not subject to a diurnal variation, but increases in correspondence with geomag- netic storms and transient enhancements of solar EUV radiation. If we increase the tem- perature at 120 km. by 50° without changing the composition, the density at 200 km. will increase, according to our models, by a little over 30 percent when the exospheric tempera- ture is about 1400° K. This is just about the order of magnitude of the erratic density changes observed in Sputnik 2 and 3. At greater heights the density change is more or less the same, decreasing only slightly with height, but its relative importance becomes smaller because of the increased response of the density to changes in the exospheric tempera- ture (or, to be more accurate, to changes in the corresponding temperature gradient above 120 km.). Satellites at heights as low as 160 km. have recently shown that the density changes during magnetic storms are in phase with those at greater heights (Zirm, 1964). This indicates that most of the heating during these storms must occur at heights considerably lower than 160 km. It therefore looks highly probable that the temperature at 120 km. must undergo changes during a magnetic storm. If we assume that also the erratic changes in solar EUV affect the temperature at 120 km., it is difficult to see how the much larger varia- tions of EUV in the course of the 11 year solar cycle could leave the temperature at 120 km. undisturbed. Perhaps there is such a change and the construction of better models will be possible when this change becomes known. 7. Comparison with recent satellite-drag data at heights below 200 km. A valuable collection of drag data on satellites with low perigee heights has been recently presented by Small (1964). These data extend in an unbroken series to heights as low as 160 km., and for one satellite (1962 pa) to 126 km. Apart from the assumed boundary conditions, our atmospheric models are based on drag data from satellites with perigee mainly above 250 km. and were completed before we had knowl- edge of Small's densities. It was gratifying to find that the agreement of these densities with our models is excellent, as can be seen from figure 4. In this plot we divided the data into three groups according to the mean exospheric temperature prevalent at the pertinent time, in addition we have separately marked the points derived from Sputnik 3 (1958 52), which are particularly numerous and may be affected by a small systematic error. According to our models log p (p= density) at 180 km. varies by about 0.2 from sunspot maximum to sunspot minimum. Since the residuals in log p for the three temperature groups do not show any clear evidence of systematic differences, we must conclude that our models represent rather well not only the average densities, but also their variations. Since, however, the density variations below 200 km. are relatively small, the agreement with observations in this region must be ascribed mainly to the boundary conditions, which are obviously satisfactory.

The residuals in log p are taken in the sense Lockheed minus present models. that is observed in figure 4 as one proceeds to greater heights is due to the increase in ampli- tude of the various types of density variations, which — for reasons stated in section 6 — we did not attempt to remove Above 200 km. the systematic density variations (diurnal, semian- nual, geomagnetic, etc.) become so large that no serious comparison can be made without taking them into account, and a check on the validity of the models is in the inner agreement of temperatures derived from densities deter- mined over a wide range of heights, such as in figUT9 3. 8. The tables Detailed data on composition and density are given in table 1 for 30 temperature profiles ending in exospheric temperatures 50° apart and ranging from 650° K to 2100° K. Table 2 gives a summary of the density data only. The boundary conditions and the temperature profiles are specified in section 3. For the acceleration of gravity we used the formula #=980.665(1 +Z/#)- 2 cm/sec" 2 , with i?=6.35677X10 8 cm. Hydrogen concentrations are given only above 500 km., as in the CIRA 1965 tables, since hydrogen cannot be considered to be in diffusion equilibrium at lower heights (Kockarts and Nicolet, 1962). Although the tables extend to a height of 1000 km., the data above 800 km. must be considered as theoretical extrapolations since accurate satellite drag data are not available at those heights. For high exospheric tempera- 781-252 0—65 2 tures (above, say, 1300°K) at which atomic oxygen is still the major constituent between 800 and 1000 km., the densities should still be reliable; however, the same cannot be said for lower exospheric temperatures. The generation of individual densities for given values of z and T„ from equations (4) and (5) is so simple that prospective users of these models may deem it preferable to use the formulae rather than the tables to obtain atmospheric densities in electronic-computer programs. In such a case, the extrapolation of the tables to heights above 1000 km., which may be necessary for the sake of continuity in numerical integrations along satellite orbits, is automatic, and the density approaches zero when z increases beyond any limit. If the tables are used and it is desired to have the density p approach a limiting value p„ rather than zero, we can recommend the procedure we have been using for some time in our numerical- integration programs. Compute b = dln p/dz= (In 10) d log 10 p/dz at 1000 km. from the tabular values of log p and use p=p» + (piooo— P-)exp [6(2—1000)]. (15) (2>1000 km.)

Abstract Tables of atmospheric density and composition are computed for a wide range of exospheric temperatures, starting from a fixed set of boundary conditions at 120 km. The diffusion equation is integrated following em- pirical temperature profiles of exponential form capable of reproducing the densities derived from satellite drag over the years. Formulae are given which relate the exospheric temperature to solar and geomagnetic activity and allow for the diurnal and semiannual variations.
