Description
NASA's GPM Ground Validation UNCA Upper Air Radiosonde IPHEx dataset contains vertical atmospheric profiles measured during the 2014 Integrated Precipitation and Hydrology Experiment. Data was collected from April 29 to June 12, 2014, in North Carolina to study warm-season orographic precipitation. Measurements include pressure, geometric height, temperature, relative humidity, dew point, wind direction, and wind speed at various tropospheric levels.
Use Cases
Validating satellite precipitation estimates from the GPM mission using in-situ atmospheric column measurements.
Analyzing relationships between vertical wind, temperature, humidity profiles and surface precipitation in complex terrain.
Studying the structure of warm-season atmospheric conditions over mountainous regions like the Southern Appalachians.
Calibrating or improving numerical weather prediction models with high-resolution upper-air observational data.
Strengths
Data provides a focused, 45-day time series during a key field campaign (IPHEx) for studying a specific meteorological phenomenon.
Includes seven core atmospheric variables (pressure, height, temperature, humidity, dew point, wind direction, speed) for a complete vertical profile.
Supported by NASA's Global Precipitation Measurement (GPM) mission, indicating use for high-profile satellite validation.
Limitations
Exact row count and total dataset size are not specified across any source.
