GPM Light Precipitation Validation Experiment Particle Images and Drop Size Data

The Gulf of Finland region is the focus of this dataset containing precipitation particle images and drop size distribution (DSD) data. It was collected by a NASA-designed Precipitation Video Imager during the Light Precipitation Validation Experiment field campaign from September 17, 2010, to May 11, 2011. The dataset supports the improvement of Global Precipitation Measurement satellite algorithms for high-latitude, light rainfall.

Use Cases

• Validating and calibrating satellite-based precipitation retrieval algorithms using ground-measured drop size distribution data.
• Analyzing the microphysical properties of light rainfall through particle images in BMP and JPG formats.
• Studying the statistical distribution of precipitation particles using DSD bin sizes and particle counts per unit time.
• Comparing average, minimum, and logarithmic DSD measurements for high-latitude meteorological conditions.

Strengths

• Provides high-latitude, light rainfall measurements specifically for satellite algorithm improvement.
• Includes both quantitative DSD data in Excel format and visual particle images in BMP and JPG formats.
• Data collection spans a defined period from September 17, 2010, to May 11, 2011.

Limitations

• Exact row count, file size, and complete column names are not provided by any source.
• Sources conflict on the last updated date: one lists 2026-03-13, another lists 2011-05-11.
