Short Summary

This dataset provides soil moisture profiles and key monthly climate variables, derived from GLDAS and ERA5-Land, specifically curated for research on ecosystem water use efficiency.

Objective

• To provide a dataset comprising soil moisture and key climate variables for research on ecosystem water use efficiency.

Study Configuration

• Spatial Scale: Not explicitly defined, but data sources (GLDAS, ERA5-Land) are global reanalysis/assimilation systems.
• Temporal Scale: Monthly (specific period not provided in this data description).

Methodology and Data

• Models used: Global Land Data Assimilation System (GLDAS) for soil moisture data generation; ERA5-Land for climate variables.
• Data sources:
  • Soil moisture (SM) from GLDAS in three vertical layers: 0–0.1 m, 0.1–0.4 m, and 0.4–1.0 m. Integrated topsoil moisture across the full 1-meter profile derived using a thickness-weighted approach.
  • Monthly climate variables from ERA5-Land: 2 m air temperature (Ta), solar radiation (Rs), 2 m dewpoint temperature (Te), and wind speed (WS).
  • Vapor pressure deficit (VPD) calculated from 2 m air temperature and 2 m dewpoint temperature data.

Main Results

• Provision of a comprehensive dataset containing soil moisture profiles and monthly climate variables (air temperature, solar radiation, dewpoint temperature, wind speed, and calculated vapor pressure deficit) suitable for ecosystem water use efficiency studies.

Contributions

• Provides a curated dataset of key hydrological and meteorological variables, specifically processed for investigating ecosystem water use efficiency, integrating data from GLDAS and ERA5-Land.

Funding

• Not specified in the provided text.
