Weather model data matched to ozone-instrument tracks (OMI)

GEOS-5 FP-IT 3D Time-Averaged Single-Level Diagnostics Geo-Colocated to OMI/Aura UV2 1-Orbit L2 Swath 13x24km V4 (OMUFPSLV) at GES DISC
atmosphere NASA GES_DISC Level 2 active
In plain English

What it measures. Selected weather-model values, such as surface pressure, surface temperature, tropopause and boundary-layer heights, and winds, matched up to the exact spots the OMI ozone instrument observed.

How it's made. Taken from the GEOS-5 weather assimilation model and re-mapped in space and time to line up with each OMI ultraviolet swath on the Aura satellite.

How & where you'd use it. Built to make the OMI team's processing easier and to support research that uses OMI products; it's a convenience and support dataset rather than a direct observation.

Official description

The GEOS-5 FP-IT 3D Time-Averaged Single-Level Diagnostics Geo-Colocated to OMI/Aura UV2 1-Orbit L2 Swath 13x24km (OMUFPSLV) provides selected parameters from GEOS-5 Forward Processing for Instrument Teams (FP-IT) assimilated product produced by the Global Modeling and Assimilation Office (GMAO) co-located in space and time with the OMI UV-2 swath. The fields in this product include boundary layer top pressure, tropopause pressure, surface pressure, surface skin temperature, and vertical wind profiles at 10m. The OMI team also provides a corresponding product for the OMI VIS swath, OMVFPSLV. The product has been generated for convenient use by the OMI/Aura team in their L2 algorithms, and for research where those L2 products are used. The original GEOS-5 FP-IT data are reported on a 0.625 deg longitude by 0.5 deg latitude grid, whereas the OMI UV-2 spatial resolution is 13km x 24km at nadir. The OMUFPSLV files are in netCDF4 format which is compatible with most netCDF and HDF5 readers and tools. Each file is approximately 45mb in size. The lead for this product is Zachary Fasnacht of SSAI. Joanna Joiner is the responsible NASA official.
