Data product available: Ozone Mapping and Profiler Suite Limb Profiler

The Suomi NPP OMPS LP Science Team is pleased to announce the release of Version 2 (V2) ozone and aerosol profile data products from the Ozone Mapping and Profiler Suite (OMPS) Limb Profiler (LP) instrument on the Suomi National Polar-orbiting Partnership (NPP) satellite. These products consist of daily files containing individual ozone profiles (0-60 km altitude range) and aerosol extinction coefficient profiles (0-40 km altitude range). OMPS LP measurements began in January 2012, and continue to the present (August 2014). Level 1 gridded radiance (L1G) orbital data sets are also available. All data files and supporting documents are available at the NASA OzoneAQ web:

These documents provide an initial evaluation of the V2 product data quality. More detailed information will be provided on the website as they become available. Preliminary results indicate that below 25 km, LP profile ozone data quality is comparable to MLS and SAGE, and significantly better than nadir profiling instruments such as SBUV, OMI, GOME and AIRS. However, above 25 km there are some known data quality issues in the V2 product that are discussed in the Data Release Notes document. The LP aerosol extinction coefficient data quality compares well with concurrent data sets from CALIPSO, GOMOS, and OSIRIS.
