ACE MERGED PLASMA+MAG DATA

This interface provides access to a field/plasma-merged 4-min ACE data set created at SPDF as part of preparing ACE data for OMNI. Input to the SPDF data set were 4-min MAG magnetic field data (PI: N.F. Ness), 64-s SWEPAM plasma data (P.I. D. McComas), and spacecraft position data, all obtained from the ACE Science Center from which needed documentation may be found. The annual files of this ASCII data set may be accessed at anonymous FTP site.
