GPM Radiosonde Profiles from Gulf of Finland Campaign

NASA's GPM Ground Validation Upper Air Radiosonde LPVEx V1 dataset contains vertical atmospheric profiles from a 2010 field campaign around the Gulf of Finland. The data, collected in September and October 2010 using Vaisala RS92 radiosondes launched from Kumpula and Vantaa, supports the validation of satellite precipitation algorithms. It provides measurements of temperature, pressure, humidity, and winds for studying light, high-altitude rainfall.

Use Cases

• Validating and improving GPM satellite precipitation retrieval algorithms using in-situ vertical profiles.
• Analyzing vertical structure of temperature, pressure, and humidity during light precipitation events.
• Studying wind patterns and atmospheric conditions in the Gulf of Finland region during autumn.
• Comparing atmospheric soundings from two distinct launch sites (Kumpula and Vantaa).

Strengths

• Data originates from a dedicated NASA GPM mission validation campaign, ensuring a clear scientific purpose.
• Provides vertical profiles of four key atmospheric variables (temperature, pressure, humidity, winds) from a specific instrument (Vaisala RS92).
• Campaign was temporally focused, with data collected over two months (September-October 2010) from two geographic locations.

Limitations

• Exact row count, dataset size, and specific column names are not provided by any source.
• Sources conflict on the 'last updated' date, with one listing 2011 and another listing a future date of 2026.
• The license is ambiguously listed as 'other-license-specified' without further details.
