GLDAS_CLSM10_M_EP: Monthly Land Surface Model Data at 1.0 Degree Resolution

NASA's GLDAS-2.1 Catchment Land Surface Model provides 34 land surface fields from January 2000 to the present. The monthly 1.0 x 1.0 degree product is an Early Product stream generated by temporally averaging 3-hourly simulations, with a latency of about 1.5 months. This dataset is produced by the National Aeronautics and Space Administration and supersedes the previous GLDAS-1 products.

Use Cases

• Modeling global soil moisture and temperature dynamics based on the 34 land surface fields.
• Analyzing long-term trends in terrestrial water storage and snow cover from January 2000 onward.
• Assimilating land surface states into weather and climate forecast models based on the Catchment-F2.5 model outputs.
• Studying the impact of precipitation and radiation forcing on land surface processes.

Strengths

• Provides 34 distinct land surface fields, offering a multi-variable view of land states.
• Covers a continuous temporal series from January 2000 to the present.
• Data is produced by NASA using the Catchment-F2.5 Land Surface Model within the Land Information System (LIS) Version 7.
• Archived in NetCDF format, a standard for scientific geospatial data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• As an Early Product, it uses forcing data without the final GPCP precipitation fields, which are added later in the main production stream.
