GPM Ground Validation Disdrometer Data for Light Rainfall

Drop size distribution data was collected by a Joss-Waldvogel disdrometer during the Light Precipitation Validation Experiment (LPVEx) field campaign. The dataset provides high-latitude, light rainfall measurements from around the Gulf of Finland between September 10 and November 9, 2010. It was created by the GPM Ground Validation team and archived by the GHRC DAAC to support the improvement of Global Precipitation Measurement satellite algorithms.

Use Cases

• Validating and improving satellite-based precipitation retrieval algorithms by comparing ground-based drop size distribution measurements.
• Analyzing the microphysical properties of light rainfall events in high-latitude coastal environments.
• Studying temporal variations in precipitation drop size spectra over a two-month autumn period.

Strengths

• Data originates from a focused NASA field campaign (LPVEx) specifically designed for satellite validation.
• Provides continuous time-series measurements over a defined two-month period from September 10 to November 9, 2010.

Limitations

• Specific column names, row counts, and file sizes are not provided by any source.
• Sources conflict on the last update date: one source lists 2026-03-13, while another lists 2010-11-09.
