These products include the following parameters: 1) Floating potential between spacecraft probe and ambient plasma ( including photoelectrons) (u0) 2) Potential between spacecraft and second product (u1) 3) Spacecraft potential (Vsc) 4) Electron density, total (ne) 5) Electron density population 1 (ne1) 6) Electron density population 2 (ne2) 7) Electron temperature mean (Te) 8) Electron temperature population 1 (Te1) 9) Electron temperature population 2 (Te2) 10) Density proxy based on spacecraft potential (nsc) (LID = urn:nasa:pds:maven.lpw.derived:data.lp.nt) * document - documents related to the MAVEN LPW derived data bundle (LID = urn:nasa:pds:maven.lpw.derived:document) Data File Naming ---------------- Data files in this bundle are named according to the following convention: mvn_lpw___
_v_r.cdf where: = MAVEN processing level of the data = A descriptor used to identify the data file type = 4-digit year of data coverage date = 2-digit month of year of data coverage date
= 2-digit day of month of data coverage date = 2-digit software version = 2-digit data file version under the specified software version Key Documents ============= Andersson, L., MAVEN LPW PDS Archive SIS - A document describing the format and content of the Langmuir Probe and Waves Instrument (LPW) Planetary Data System (PDS) data archive. It includes descriptions of the data products and associated metadata, and the archive format, content, and generation pipeline. This document is located in the document collection of the MAVEN LPW bundle. (LID = urn:nasa:pds:maven.lpw:document:sis). Contacts ======== 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.
