OMUFPSLV: GEOS-5 Atmospheric Diagnostics Co-Located with OMI/Aura Satellite Swaths

GEOS-5 FP-IT 3D Time-Averaged Single-Level Diagnostics Geo-Colocated to OMI/Aura UV2 1-Orbit L2 Swath 13x24km V4 (OMUFPSLV) provides selected atmospheric parameters from the GEOS-5 Forward Processing for Instrument Teams assimilated product, spatially and temporally matched to the Ozone Monitoring Instrument (OMI) UV-2 swath. The product includes fields such as boundary layer top pressure, tropopause pressure, surface pressure, surface skin temperature, and vertical wind profiles at 10m. Each file is approximately 45mb in netCDF4 format, generated for use by the OMI/Aura team and for research involving their Level 2 products.

Use Cases

• Validate OMI Level 2 atmospheric composition products based on co-located GEOS-5 model diagnostics.
• Analyze vertical wind profiles at 10m for boundary layer and tropospheric studies.
• Study surface skin temperature and pressure relationships using model data aligned with satellite observations.
• Investigate tropopause pressure dynamics in regions covered by the OMI UV-2 swath.

Strengths

• Data is co-located in space and time with the OMI UV-2 swath, facilitating direct comparison.
• Files are in netCDF4 format, which is compatible with most netCDF and HDF5 readers and tools.
• Each data file is approximately 45mb in size, indicating a manageable download and storage footprint.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale statistical analysis.
