Wyoming King Air Cloud Microphysics Data for Satellite Validation

NASA's GPM Ground Validation Wyoming King Air Cloud Microphysics LPVEx dataset contains airborne measurements from the Light Precipitation Evaluation Experiment. Data were collected over the Gulf of Finland from September 11 to October 20, 2010, to validate satellite precipitation algorithms. The University of Wyoming King Air aircraft carried instruments including a Cloud Microphysics probe and the Wyoming Cloud Radar.

Use Cases

• Validating satellite-based precipitation retrieval algorithms using in-situ measurements of liquid water content and droplet concentration.
• Studying cloud microphysical processes leading to light rainfall formation in high-latitude marine environments.
• Analyzing relationships between atmospheric state variables like static pressure, dew point, and relative humidity with cloud properties.
• Calibrating or assessing airborne radar data from the Wyoming Cloud Radar with coincident microphysical observations.
• Investigating aircraft attitude and speed parameters in relation to scientific sampling during field campaigns.

Strengths

• Data includes specific, calibrated scientific parameters like static pressure, dew point temperature, and droplet concentration.
• Covers a focused 40-day campaign (September 11 - October 20, 2010) for a dedicated scientific objective.
• Collected by a recognized research institution (University of Wyoming) using specialized aircraft instrumentation.
• Dataset is available on multiple authoritative platforms (Data.gov and NASA Earthdata), indicating curation and importance.

Limitations

• Exact row count, file size, and complete column list are not provided by any source.
• Sources conflict on the 'last updated' metadata, with dates ranging from 2010 to 2026.
• License is ambiguously listed as 'other-license-specified' on Data.gov but is 'None' on NASA Earthdata.
