This is a CloudSat-collocated subset of the original product OMNO2, for the purposes of the A-Train mission. The goal of the subset is to select and return OMI data that are within +-100 km across the CloudSat track. I.e. the resultant OMI subset swath is sought to be about 200 km cross-track of CloudSat. This product also contains many ancillary and derived parameters, terrain and geolocation ... information, solar and satellite viewing angles, and quality flags. Even though collocated with CloudSat, this subset can serve many other A-Train applications.
The version 003 product is the second public release. The quality of this v003 product is based on preliminary calibration algorithm and this product is not fully validated yet. Please see the detailed Quality assessment ... document provided by Algorithm Leads. Though overall quality of Column NO2 parameters are satisfactory, users are strongly advised to consult the OMI Quality Assurance Team for most recent information on our ongoing assessment of OMNO2 data quality.
