ATMOWeb: Satellite Observations of 
Ionosphere and Upper Atmosphere


SPDF ATMOSPHERIC EXPLORER-C (AE-C) DATA SCATTER PLOT

This interface provides listing and plotting capabilities for the 15-second merged mission data (79 science parameters and 9 orbit parameters) from the AE-C spacecraft. AE-C was first in an elliptical orbit until mid-75, than changed to a circular orbit at about 300km, and the orbit altitude was changed to about 400 km in mid-77. AE-C's orbit inclination was 68 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.
