ECOSTRESS L2 Land Surface Temperature and Emissivity

ECOSTRESS L2 Land Surface Temperature and Emissivity is an open NASA EOSDIS Level 2 product distributed through Earthdata for ECOSTRESS swath observations from the International Space Station orbit ^[1]. It provides land surface temperature and emissivity outputs at 70 m ground sampling distance from five thermal infrared bands spanning 8000 to 12500 nm, delivered as HDF5 files ^[1].

For buyers evaluating thermal workflows, the product is useful for urban land-surface temperature mapping, evapotranspiration and plant-water-stress analysis, and thermal anomaly screening ^[1]. Its 70 m pixels are suitable for district or block-scale analysis, but they can mix roofs, roads, vegetation, and facades in building-level work ^[1]. Coverage is limited by the ISS orbit to roughly 52 degrees north through 52 degrees south, and ECOSTRESS acquisition history includes gaps and a reduced-band operating period that should be checked against project dates ^[1].
