Level 2
Version 2.0Now depreciated
Version 2.00 (v2.02.07)Now depreciated
Version v3.00 (v02-04-09) Now depreciated - this release contained one data file per day includes T, O3, HNO3 and Cloud tops data
Version v4.00 (v02-04-19) Now depreciated. This release added three new data products (F11, F12 and aerosol extinction),
and significantly enhances those previously available (T, O3, HNO3, Cloud tops)
Version v5.00 This release includes geopotential height (GPH) as a new product. The latest version (7.1) of IDL may be required in order to read this data.
This is because the L2 processor used to produce this data version uses the latest version of the Toolkit(5.2.16) which uses HDF5 1.8.3.

* Version v6.00 Released end 2010. This includes new level 3 products:
  • daily zonal means of daytime and nighttime NO2
  • daily zonal means of nighttime N2O5
  • daily grids of daytime stratospheric columns of NO2
  • monthly mean cirrus Ice Water Content (a joint HIRDLS/MLS product)
The latest version (7.1) of IDL may be required in order to read this data.

auxiliary_files utcpole.dat.YYYYDDD* ECS internal format for daily values of UT1 - UTC and the x and y components of polar motion.
auxiliary_files leapsec.dat.YYYYDDD* ECS internal format for Toolkit for time difference TAI - UT; From 1961 to 1971, approximate equivalent to TAI-UT
204 is the AURA spacecraft ID
the next 4 digit number is the Level0 APID (application id),
following the 14 As is the time in YYDDDHHMMSS.XXX format
files ending .met contain metadata pertaining to the file of the same name (minus the .met)
