Short Summary

This dataset provides processed soil moisture data from the Global Land Data Assimilation System (GLDAS) and monthly climate variables from ERA5-Land, specifically curated for research on ecosystem water use efficiency.

Objective

• To provide a comprehensive dataset of integrated soil moisture profiles and key climate variables for studies on ecosystem water use efficiency.

Study Configuration

• Spatial Scale: Global (inferred from GLDAS and ERA5-Land data sources)
• Temporal Scale: Monthly (for climate variables); specific duration of data not specified.

Methodology and Data

• Models used: Not explicitly stated, but data sources (GLDAS, ERA5-Land) are derived from land surface and atmospheric models.
• Data sources:
  • Soil moisture (SM) data from Global Land Data Assimilation System (GLDAS) in three vertical layers: 0–0.1 m, 0.1–0.4 m, and 0.4–1.0 m. An integrated 1-meter topsoil moisture profile was derived using a thickness-weighted approach.
  • Monthly climate variables from ERA5-Land dataset: 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

• The output of this work is a dataset comprising integrated 1-meter 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

• Provision of a curated dataset combining multi-layer soil moisture and essential climate variables, specifically processed and integrated for applications in ecosystem water use efficiency research.

Funding

• Not specified in the provided text.
