Data Products
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 5 (V5) Level 2 and Level 3 products for CO vertical profiles and total column are available for the entire MOPITT mission (March, 2000 - present). Three Level 2 retrieval variants are offered for V5: A thermal infrared-only (TIR-only) product, similar to the V4 product; a new near infrared-only (NIR-only) product; and a new joint or multispectral TIR/NIR product. At this time, the V5 TIR-only product is considered 'provisionally validated' whereas the NIR-only and joint TIR/NIR products are considered 'beta'-grade products.
- Version 4 (V4) products for CO vertical profiles and total column will continue to be processed operationally at least through the end of 2011. The V4 product is considered 'validated.' Level 1 radiances (daily), Level 2 CO (daily) and Level 3 CO (daily and monthly) products are available for March, 2000 to the present.
- Version 3 (V3) products for CO vertical profiles and total column are archived for March, 2000 through July, 2009. V3 processing ceased on July 31, 2009.
- Version 2 (V2) products were produced only immediately after launch and are no longer available.
