MemberValueDescription
e1976StandardAtmosModel01976 Standard Atmosphere: look-up model based on the satellite's altitude, with a valid range of 86km - 1000 km.
eCira721CIRA 1972: empirical model of atmospheric temperature and densities as recommended by the Committee on Space Research (COSPAR). Lower altitude boundary is 90 km.
eExponentialModel2This enumeration is deprecated. This option is no longer available for IAgVeHPOPForceModelDrag. If used for IAgVeAdvanced, use AgELOPAtmosphericDensityModel instead. Exponential Model: uses equation calculating atmospheric density on basis of a specified altitude, reference density, reference altitude and scale altitude.
eHarrisPriester3Harris-Priester: takes into account a 10.7 cm solar flux level and diurnal bulge. Uses density tables. Valid range of 0-1000 km.
eJacchiaRoberts4Jacchia-Roberts: similar to Jacchia 1971 (below) but uses analytical methods to improve performance. Lower altitude boundary is 90 km.
eJacchia605Jacchia 1960: outdated atmospheric model provided for making comparisons with other software. Lower altitude boundary is 0 km.
eJacchia706Jacchia 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.
eJacchia717Jacchia 1971: similar to Jacchia 1970 (above), with improved treatment of certain solar effects.
eMSIS008NRLMSISE 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.
eMSIS869MSIS 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.
eMSIS9010MSISE 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.
eUnknownDensModel11Unsupported or unknown atmospheric density model.
eUserDefined12This enumeration is deprecated. This option is no longer available for IAgVeHPOPForceModelDrag. User-defined atmospheric density model.
eDTM201213DTM 2012: The Drag Temperature Model (DTM), 2012 version, is a semi-empirical model which computes the temperature, density, and composition of the thermosphere. Developed at CNES. Valid range of 120 - 1500 km.
eDTM202014DTM 2020: The Drag Temperature Model (DTM), 2020 version, is a semi-empirical model which computes the temperature, density, and composition of the thermosphere. Developed at CNES. Valid range of 120 - 1500 km.
