ECOSTRESS: Global Downscaled Air Temperature and Humidity at 70 m Resolution

The ECOSTRESS Tiled Downscaled Meteorology Instantaneous L3 Global 70 m V002 data product provides instantaneous near-surface air temperature and relative humidity estimates. It is produced by NASA using linear regression with ECOSTRESS surface temperature, NDVI, and albedo data, downscaled to a 70-meter spatial resolution and tiled globally between 52° N and 52° S latitudes. The product contains four layers including Ta, RH, cloud mask, and water mask.

Use Cases

• Modeling plant water stress based on near-surface air temperature and humidity estimates.
• Analyzing microclimate variations using the 70-meter spatial resolution meteorological data.
• Masking cloud and water-covered areas for land surface analysis using the provided cloud and water mask layers.
• Calibrating or validating regional climate models with downscaled, satellite-derived temperature and humidity data.

Strengths

• Provides data at a 70-meter spatial resolution, which is a high level of detail for meteorological variables.
• Contains four distinct data layers: air temperature, relative humidity, cloud mask, and water mask.
• Data is collected globally between 52° N and 52° S latitudes, offering broad geographic coverage.
• The product is provided in Cloud Optimized GeoTIFF (COG) format, which is optimized for cloud-based access.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes known data acquisition gaps due to instrument anomalies, which may affect temporal continuity.
• Row count is unknown, which may limit suitability assessment.
