Data File Naming
----------------
Data files in this bundle are named according to the following convention:
mvn_lpw_❮level❯_❮desc❯_❮yyyy❯❮mm❯❮dd❯_v❮xx❯_r❮yy❯.cdf
where:
❮level❯ = MAVEN processing level of the data
❮desc❯ = A descriptor used to identify the data file type
❮yyyy❯ = 4-digit year of data coverage date
❮mm❯ = 2-digit month of year of data coverage date
❮dd❯ = 2-digit day of month of data coverage date
❮xx❯ = 2-digit software version
❮yy❯ = 2-digit data file version under the specified software version

This archive was produced for the Planetary Data System (PDS) at the Planetary
Plasma Interactions (PPI) node at the University of California, Los Angeles
(UCLA). The data files were generated by Dr. Laila Andersson at the Laboratory
for Atmospheric and Space Physics (LASP) in Boulder, Colorado. The data were
delivered to the PPI node via the MAVEN Science Data Center (SDC) also located
at the LASP in Boulder, Colorado. The PDS metadata were generated at the PPI
node.
