ATMOWeb: Satellite Observations of Ionosphere and Upper Atmosphere


This interface provides listing and plotting capabilities for the 15-second merged mission data (79 science parameters and 9 orbit parameters) from the AE-E spacecraft. AE-E was first in an elliptical orbit (150 - 4300 km) until mid-77 and than changed to a circular orbit at about 400km. AE-E's orbit inclination was 19.7 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.
