Global Plant Temperature and Meteorology Data at 70-Meter Resolution

ECOSTRESS data measures plant temperature from the International Space Station to assess water needs and stress responses. The product provides instantaneous near-surface air temperature and relative humidity estimates downscaled to a 70-meter spatial resolution globally between 52° N and 52° S latitudes. This Level 3 tiled product is generated by NASA's LPCLOUD using linear regression with surface temperature, NDVI, and albedo as predictors.

Use Cases

• Model plant water stress by correlating downscaled near-surface air temperature (Ta) layers with surface temperature (ST) and normalized difference vegetation index (NDVI).
• Assess microclimate humidity for agricultural zones using the relative humidity (RH) layer bias-corrected with GEOS-5 FP data.
• Mask out non-land areas for analysis by applying the provided cloud mask and water mask layers to the core data tiles.
• Analyze spatial patterns of thermal stress by examining the 70-meter resolution Ta data across 109.8 km x 109.8 km MGRS tiles.

Strengths

• 70-meter spatial resolution provides fine-scale environmental detail.
• Global coverage between 52° N and 52° S latitudes.
• Product contains four specific data layers: Ta, RH, cloud mask, and water mask.

Limitations

• Data acquisition experienced multiple gaps and anomalies in 2018-2019 and 2020, affecting temporal continuity.
• Specific technical bands contain fill values for periods after May 15, 2019, due to a modified acquisition approach.
• The exact temporal range and total number of observation tiles are not specified in the provided description.
