|---|---|---|
| e1976StandardAtmosModel | 0 | 1976 Standard Atmosphere: look-up model based on the satellite's altitude, with a valid range of 86km - 1000 km. |
| eCira72 | 1 | CIRA 1972: empirical model of atmospheric temperature and densities as recommended by the Committee on Space Research (COSPAR). |
| eExponentialModel | 2 | Exponential Model: uses equation calculating atmospheric density on basis of a specified altitude, reference density, reference altitude and scale altitude. |
| eHarrisPriester | 3 | Harris-Priester: takes into account a 10.7 cm solar flux level and diurnal bulge. Uses density tables. Valid range of 0-1000 km. |
| eJacchiaRoberts | 4 | Jacchia-Roberts: similar to Jacchia 1971 (below) but uses analytical methods to improve performance. |
| eJacchia60 | 5 | Jacchia 1960: outdated atmospheric model provided for making comparisons with other software. |
| eJacchia70 | 6 | Jacchia 1970: computes atmospheric density based on the composition of the atmosphere, which depends on altitude as well as seasonal variation. Valid range is 100-2500 km. |
| eJacchia71 | 7 | Jacchia 1971: similar to Jacchia 1970 (above), with improved treatment of certain solar effects. |
| eMSIS00 | 8 | NRLMSISE 2000: finds the total density by accounting for the contribution of N, N2, O, O2, He, Ar and H. Includes anomalous oxygen. 2000 version, valid range of 0-1000 km. |
| eMSIS86 | 9 | MSIS 1986: finds the total density by accounting for the contribution of N2, O, O2, He, Ar and H. 1986 version, valid range of 90-1000 km. |
| eMSIS90 | 10 | MSISE 1990: finds the total density by accounting for the contribution of N2, O, O2, He, Ar and H. 1990 version, valid range of 0-1000 km. |
| eUnknownDensModel | 11 | Unknown atmospheric density model. |
| eUserDefined | 12 | User-defined atmospheric density model. |
