DE 2 2s Retarding Potential Analyzer (RPA) Ion Plasma Parameters

This data set contains the following plasma parameters at 16ms resolution from the DE 2 Retarding Potential Analyzer: ion drift velocity, ion temperature, densities of all ions and of O+, H+, He+, molecular, and high mass ions. Data are available in ASCII from nssdcftp and in CDF format from CDAWeb (as well as CDAWeb plots and lists). The data span the 18-month DE 2 lifetime, except for a gap from 1981/317 to 1982/041.
