MOPITT retrievals of carbon monoxide vertical profiles and total column are available for the period starting March 3, 2000 and continuing to the present. There is no operational MOPITT product for methane, due to a variety of problems with the methane-channel radiances. Some of these issues are documented in the 2005 paper "Effects of a spectral surface reflectance on measurements of backscattered solar radiation: Application to the MOPITT methane retrieval" by Pfister et al. (see MOPITT publications ).

Available Products

  • Version 4 (V4) products for CO vertical profiles and total column are currently being processed operationally and will be archived as they are completed. Level 1 radiances (daily), Level 2 CO (daily) and Level 3 CO (daily and monthly) products are available for March, 2000 to the present (except for the period from May 7, 2001 to August 24, 2001, due to an instrument malfunction).
  • Version 3 (V3) products for CO vertical profiles and total column are currently being processed operationally and will be archived as they are completed. V3 processing will cease on July 31, 2009. Users of the V3 product should begin using the V4 product as soon as possible.  Level 1 radiances (daily), Level 2 CO (daily) and Level 3 CO (daily and monthly) products are available for March, 2000 to the present (except for the period from May 7, 2001 to August 24, 2001, due to an instrument malfunction).
  • Version 2 (V2) products were produced only immediately after launch and are no longer available.
