ATMOWeb: Satellite Observations of Ionosphere and Upper Atmosphere


DYNAMICS EXPLORER 2 (DE-2) DATA

This page lets user list and plot 16-second ionospheric/thermospheric data obtained by NASA's DE-2 spacecraft between August 06, 1981 and February 15, 1983. (spacecraft operations ceased on February 19). The DE-2 orbit was high-inclination and elliptical (300-1000 km).

The user can download daily files in ASCII format from SPDF's anonymnous ftp site spdf.gsfc.nasa.gov in directory spacecraft_data/de/de2/combined_plasma_neutrals_ua/de2_ua/.

Time span of the data set: 1981-08-06 - 1983-02-15
