SMEX02 Flux Tower Radiometric and Atmospheric Data for Walnut Creek

2002 data from the Soil Moisture Experiment 2002 (SMEX02) collected at 12 flux towers in Walnut Creek, Iowa. The dataset includes air temperature, vapor pressure, wind speed, and brightness temperatures. It is provided by the NSIDCV0 organization.

Use Cases

• Validating satellite-derived soil moisture products using ground-based brightness temperature measurements.
• Analyzing relationships between atmospheric conditions (air temperature, vapor pressure, wind speed) and surface energy exchange.
• Studying spatial and temporal variability of surface temperature during an agricultural field experiment.
• Calibrating or testing microwave emission models with in-situ radiometric data.

Strengths

• Data is sourced from 12 instrumented flux towers, providing multiple spatial observation points.
• Covers key variables for surface energy balance studies: air temperature, vapor pressure, wind speed, and brightness temperatures.

Limitations

• Conflicting last updated dates exist between sources: one states 2003-07-12, another states 2026-03-12.
• Specific column names, row counts, and file sizes are not provided by any source.
