GPM Satellite Simulated Orbits for TWP-ICE Ground Validation

2006 data from the Tropical Warm Pool-International Cloud Experiment (TWP-ICE) in Australia provides simulated satellite orbits for ground validation. The dataset models sensor-specific observations from GMI and DPR instruments using high-resolution Cloud-Resolving Model profiles for atmospheric conditions, clouds, and precipitation. It is produced by the Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) for NASA's Global Precipitation Measurement mission.

Use Cases

• Validating GPM satellite precipitation retrieval algorithms against high-resolution model data.
• Studying the sensitivity of microwave brightness temperature to cloud and rain profiles from CRM outputs.
• Analyzing simulated orbital geometry and sensor-specific fields of view for the GMI imager, sounder, and DPR frequencies.
• Comparing simulated Level 1B/Level 2-like parameters across different ground validation campaigns (e.g., TWP-ICE, MC3E, LPVEX).

Strengths

• Simulations incorporate detailed sensor geometry and antenna gain patterns for five distinct GPM instruments.
• Based on high-resolution Cloud-Resolving Model data providing detailed atmospheric, cloud, rain, and surface profiles.
• Dataset is part of a multi-campaign series, allowing for cross-experiment analysis of satellite simulations.

Limitations

• Specific row counts, file sizes, and a complete column list are not provided by any source.
• Sources conflict on the last updated date, listing both 2006-02-06 and 2026-03-13.
• License is ambiguously listed as 'other-license-specified' or 'None' across different entries.
