Measurements Of Pollution In The Troposphere (MOPITT)

The MOPITT Mission

MOPITT is an instrument flying on NASA's Earth Observing System Terra spacecraft, measuring tropospheric carbon monoxide (CO) on the global scale. MOPITT measurements enable scientists to analyze the distribution, transport, sources and sinks of CO, a trace gas produced by methane oxidation, fossil fuel consumption and biomass burning. MOPITT has been operational since March 2000.

MOPITT Product Availability

MOPITT Version 6 Level 2 and Level 3 products are now available for the entire MOPITT mission.  Generally, V6 Level 2 and Level 3 products should become available between three weeks and two months after the actual observations; this data latency is the result of the dependency on the MERRA reanalysis. Version 4 and Version 5 Level 2 and Level 3 products are also available.  See Data Products for descriptions of the different products.  User's Guides available on the Publications page should be consulted before attempting to analyze the MOPITT products.
