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

GEOS-5 FP-IT model parameters, including boundary layer top pressure and vertical wind profiles, are co-located in space and time with the OMI/Aura satellite's UV-2 swath. Each data file is approximately 45mb in size and is provided in netCDF4 format for compatibility. The product was generated for the OMI/Aura team's L2 algorithms and related research, with Zachary Fasnacht of SSAI as the lead.

Use Cases

• Validate satellite-derived atmospheric pressure measurements based on co-located GEOS-5 model surface and tropopause pressure fields.
• Analyze vertical wind profiles at 10m for boundary layer studies based on the model diagnostics provided.
• Correlate satellite-observed UV data with modeled surface skin temperature for climate research.
• Study spatial consistency between a 0.625°x0.5° model grid and 13kmx24km satellite swath data.

Strengths

• Data is spatially and temporally co-located between the GEOS-5 model and the OMI/Aura satellite swath, facilitating direct comparison.
• Files are in netCDF4 format, which is compatible with most netCDF and HDF5 readers and tools.
• The product is generated by NASA's Global Modeling and Assimilation Office (GMAO), an authoritative source for atmospheric modeling.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
