IPHEx Campaign Rainfall Rates from Satellite Fusion Algorithm

SCaMPR algorithm rainfall rate data combines GOES infrared and microwave estimates from SSM/I and AMSU sensors for calibration. The dataset covers the 49-day IPHEx field campaign from April 30 to June 17, 2015, designed to study warm-season precipitation in complex terrain. It is produced by the GPM Ground Validation team and distributed by the GHRC DAAC.

Use Cases

• Validating satellite-based precipitation products against ground observations.
• Analyzing the spatial and temporal patterns of warm-season rainfall in mountainous regions.
• Studying the relationship between infrared cloud-top data and surface rainfall rates.
• Calibrating and improving multivariate precipitation retrieval algorithms.

Strengths

• Data is derived from a fusion of GOES IR and microwave (SSM/I, AMSU) satellite sensors, providing a multi-sensor estimate.
• Specifically calibrated for a 49-day intensive field campaign (IPHEx) focused on complex terrain.
• Available in netCDF-4, a standard format for geospatial and time-series scientific data.

Limitations

• Exact row count, file size, and specific column names are not provided by any source.
• Sources conflict on the last updated date, listing both 2014-06-16 and 2026-03 -13.
• Spatial coverage (geography) is not explicitly defined in the provided descriptions.
