GLDAS CLM10SUBP_3H: Global Land Surface Parameters at 1.0 Degree, 3-Hourly

January 1979 to present land surface parameters simulated from the Common Land Model (CLM) V2.0 within the Global Land Data Assimilation System (GLDAS). The data are provided at a 1.0-degree spatial resolution with a 3-hourly temporal resolution, forced by atmospheric analysis and observation-based radiation fields. This dataset is produced and hosted by the National Aeronautics and Space Administration (NASA).

Use Cases

• Modeling land surface energy and water balance based on simulated parameters like soil moisture and temperature.
• Analyzing long-term trends in hydrological variables such as precipitation and snow cover.
• Validating other climate or weather models using the assimilated, observation-forced simulation outputs.
• Studying diurnal cycles of surface thermal properties based on the 3-hourly temporal resolution.

Strengths

• Provides continuous data from January 1979 to the present, offering over 40 years of historical simulation.
• Simulation is forced by a combination of NOAA/GDAS analysis and observation-based radiation fields, suggesting assimilation of real-world data.
• Offers high temporal granularity with 3-hourly data, which can capture diurnal cycles.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic or temporal bias inherent to the forcing models and input data sources.
