ATMOWeb: Satellite Observations of Ionosphere and Upper Atmosphere


SPDF ATMOSPHERE EXPLORER-D (AE-D) DATA

This interface provides listing and plotting capabilities for the 15-second merged mission data (63 science parameters and 9 orbit parameters) from the AE-D spacecraft. AE-D was in an elliptical orbit (150 - 3800 km) and had an orbit inclination of 90 degrees.

Note: Because of duty cycle limitations there are many data gaps (even several days). The daily ASCII files at our spdf site provide an indication of which days are available.
