Description
Soil and atmospheric data were collected from a Soil Climate Analysis Network station in Little River, Georgia, USA, during the Soil Moisture Experiment 2003 (SMEX03). The dataset covers a two-month period from June 1 to July 31, 2003, and was produced by the National Aeronautics and Space Administration. It includes measurements of soil moisture, soil temperature, precipitation, air temperature, humidity, wind speed, and wind direction.
Use Cases
Validating satellite-based soil moisture retrieval algorithms using ground-truth soil moisture and temperature measurements.
Analyzing the relationship between precipitation events and subsequent changes in soil water content.
Studying diurnal and seasonal variations in near-surface atmospheric conditions (air temperature, humidity, wind) over an agricultural region.
Calibrating or evaluating hydrological and land surface models with a time-series of co-located soil and weather variables.
Strengths
Data originates from a controlled field experiment (SMEX03) designed for soil moisture validation.
Provides co-located, simultaneous measurements of multiple key soil and atmospheric variables.
Covers a continuous two-month observation period (June 1 - July 31, 2003) during a critical growing season.
Limitations
The exact number of data rows, file size, and specific column names are not provided by any source.
