GPM Satellite Simulated Orbits for LPVEx Ground Validation

This dataset contains simulated satellite orbit data for the GPM Ground Validation LPVEx campaign in Finland, 2010. It models sensor-specific geometry and antenna patterns for instruments like the GMI imager and DPR radar, generating simulated Level 1B/2-like parameters over a Cloud-Resolving Model domain. The data is provided by the GHRC DAAC in NetCDF3 format.

Use Cases

• Validating satellite precipitation retrieval algorithms by comparing simulated brightness temperatures and radar reflectivity with ground observations.
• Studying sensor synergy by analyzing co-located simulated data from the GMI microwave imager and the DPR Ku, Ka_MA, and Ka_HS radar channels.
• Assessing the impact of detailed surface/terrain and atmospheric profiles from a Cloud-Resolving Model on simulated satellite observations.

Strengths

• Simulations account for unique sensor geometry and antenna gain patterns for five distinct instruments (GMI imager, GMI sounder, DPR Ku, DPR Ka_MA, DPR Ka_HS).
• Data is derived from a Cloud-Resolving Model database providing detailed atmospheric, cloud/rain, and surface/terrain profiles.
• Dataset is part of a multi-campaign series including MC3E (2011), C3VP (2007), and TWP-ICE (2006), indicating a consistent methodology.

Limitations

• Key metrics like row count and dataset size are not provided by any source platform.
• There is a conflict in the 'last updated' metadata, with one source stating 2026-03-13 and another 2010-10-21, creating uncertainty about data currency.
