Data Portal

Go here to find access to processed and validated (Level 1) cdf files and some ascii data files for IMPACT magnetometer and SEP data. Information is also provided on some TPLOT IDL routines that can be used to plot these data. Use the link to the magnetometer data to access an ascii Level 2 key parameter data set merged with PLASTIC plasma ion moments and Level 3 STEREO IMPACT event lists.

In-situ Event Lists

Go here to find STEREO event lists for ICMEs (Interplanetary Coronal Mass Ejections), SIRs (Solar wind stream interaction structures), SEP (Solar Energetic Particle) events and Interplanetary Shocks.
