Level 2 THEMIS CDF files contain THEMIS calibrated data quantities in physical units. These data can be used by scientists directly; the instrumental details have been accounted for in the calibration process. Level 2 data files are stored in the permanent archive at UCB and are distributed to mirror sites and the SPDF. Level 2 data files are created daily using Level 1 data and calibration data and are updated and reprocessed when necessary. For example, updates in calibration data for a given instrument/time period will result in new Level 2 data files for that instrument and time period. Currently (as of June 2008), there are Level 2 files for ESA, SST, FBK, MOM, FIT (onboard), GMAG and FGM data. By December 2008, daily processing of EFI, FFT (onboard), STATE, and SCM Level 2 data files will commence. By the end of the mission there will be an L2 ASK cdf as well.
