GPM LPVEx Mast Meteorological Data from Helsinki

Meteorological measurements from the SMEAR III Kumpula Mast in Helsinki, Finland, collected during the GPM Light Precipitation Validation Experiment (LPVEx). The dataset includes temperature, radiation, and wind data from September 17 to October 21, 2010, supporting satellite algorithm validation for high-latitude light rainfall. It is managed by the GHRC DAAC under NASA's Global Precipitation Measurement mission.

Use Cases

• Validating and improving GPM satellite precipitation retrieval algorithms using ground-based temperature and wind measurements.
• Studying ecosystem-atmosphere interactions in a boreal coastal zone using radiation and temperature data.
• Analyzing surface meteorological conditions during light precipitation events for climate model evaluation.
• Investigating photosynthetically active radiation (PAR) dynamics in relation to atmospheric conditions.

Strengths

• Data originates from the established Station for Measuring Ecosystem-Atmosphere Relations III (SMEAR III) mast, a dedicated research facility.
• Provides a focused 35-day time series (Sept 17 - Oct 21, 2010) for a specific field campaign targeting light precipitation.
• Includes multiple measurement types: temperature, radiation (longwave, net, shortwave, PAR), and surface winds.

Limitations

• Exact row count, file size, and complete column list are not provided by any source.
• Sources conflict on the last updated date: one states 2026-03-13, another states 2010-10 21.
• Data is limited to a single autumn season and one geographic location (Helsinki, Finland).
