MOPITT data and tools available from the Atmospheric Sciences Data Center

The Measurements Of Pollution In The Troposphere (MOPITT) instrument measures carbon monoxide and methane in the troposphere over the entire globe. It was launched onboard the NASA Earth Observing System (EOS) Terra satellite in December 1999. MOPITT data products are archived and distributed by the Atmospheric Sciences Data Center (ASDC) at NASA´s Langley Research Center. Available MOPITT data products include Level 1 radiances and Level 2 derived carbon monoxide total column and mixing ratio profiles at a horizontal resolution of about 22 km at nadir and a vertical resolution of about 4 km. The ASDC also makes available tools that aid in the visualization and analysis of the MOPITT Level 2 data products. The MOPITT L2 Viewer software package plots images from the MOPITT Level 2 data files. Sample read software extracts data from a MOPITT Level 2 HDF-EOS formatted file and outputs the data in ASCII. The software also allows subsetting by latitude and longitude. Detailed information about the MOPITT data products, tools and documentation is available from the ASDC web site.
