File Naming Convention

There are currently two FPI L2 files per species, mode, and observatory: moments and distributions. The L2 file naming convention is <obs>_fpi_<mode>_l2_<tag>_<YYYYMMDDHHMMSS>_v<x.y.z>.cdf, where:

• <obs> is one of: mms1, mms2, mms3, mms4
• <mode> is one of: brst, fast, slow
• <tag> is one of: des-dist, des-moms, dis-dist, dis-moms
• <YYYYMMDDhhmmss> is the date time tag of the first record in the file
• <x.y.z> is the version of the FPI ground system software used to generate the file

Variable Naming Convention

Moments and distribution variables utilize the convention of <obs>_<species>_<varname>_<mode>, where:

• <obs> is one of: mms1, mms2, mms3, mms4
• <species> is one of: des, dis
• <varname> is the variable name in the tables below
• <mode> is one of: brst, fast, slow
