The Jacchia Reference Atmospheres were published as reports in 1970, 1971, and 1977. These publications include explanatory text, formulas, and tables. The density, temperature, and composition are listed in the altitude range 90 km to 2500 km. Variations with season, latitude, and local time are considered. Auxiliary tables are provided to evaluate geomagnetic, semi-annual, and seasonal-latitudinal effects. Jacchia's models are based mostly on satellite drag data. Assuming diffusive equilibrium, the atmospheric profiles are defined by the exospheric temperature. He contributed the thermospheric part (110 km to 200 km) to the CIRA-72 model. Jacchia (1964) was the first to point out the coupling between solar wind and atmosphere.
