JWL This data set contains 96s and 384s resolution magnetic field and plasma ion data from the THEMIS-B ESA and FGM instruments during the near moon (ARTEMIS) phase of the spacecraft life (>~September 1, 2010). The data are at each resolution for several mutually exclusive, contiguous hours during most days. The field-plasma-merged data set was created at GSFC/Space Physics Data Facility (SPDF) as part of the LunaSOX effort, from CDAWeb data sets THB_L2_ESA (good quality, high angular resolution mode only) and THB_L2_FGM. Geocentric spacecraft and moon orbit data from SSCWeb were used to add geocentric and selenocentric spacecraft position data to the merged data set records.
