GLDAS_NOAH10_M_EP: Global Land Surface Variables, Monthly 1.0 Degree Grid from 2000

36 land surface fields are provided from January 2000 to present, generated by NASA's Global Land Data Assimilation System (GLDAS-2.1). The monthly data product is an Early Product with about 1.5 month latency, created by temporally averaging 3-hourly simulations from the Noah Model 3.6. It is forced with a combination of NOAA/GDAS atmospheric analysis, GPCP precipitation, and AGRMET radiation fields.

Use Cases

• Modeling soil moisture and temperature dynamics based on the 36 included land surface fields.
• Analyzing long-term trends in terrestrial water storage based on the continuous record from 2000.
• Assimilating near-real-time land surface states into weather and climate forecasts based on the Early Product's 1.5-month latency.
• Studying the impact of precipitation forcing on hydrological cycles based on the GPCP and GDAS input data mentioned.
• Validating other land surface or climate models against this assimilated product.

Strengths

• Contains 36 distinct land surface fields for analysis.
• Provides a temporally consistent series from January 2000 to the present.
• Archived in NetCDF format, a standard for geoscientific data.

Limitations

• Description metadata is limited; actual data quality and field semantics require manual inspection after download.
• Column-level documentation is absent; field definitions must be inferred from external sources.
• This is an Early Product stream which is later superseded by a main production stream, indicating provisional data.
