Description
Global data between 52° N and 52° S latitudes provides land surface temperature and emissivity derived from five thermal infrared bands. The dataset is tiled into 109.8 km squares with a 70-meter spatial resolution, processed using a physics-based Temperature and Emissivity Separation algorithm. It contains seven layers including LST, LST error, wideband emissivity, quality flags, height, and cloud and water masks.
Use Cases
Monitoring plant water stress and irrigation needs based on land surface temperature measurements.
Validating and improving land surface models using atmospherically corrected temperature and emissivity values.
Analyzing urban heat island effects using high-resolution (70m) thermal data over cities.
Assessing wildfire risk and post-fire recovery through surface temperature anomalies.
Studying diurnal temperature cycles and energy balance using instantaneous observations from the ISS.
Strengths
Provides high-resolution (70m) thermal infrared data, which is relatively fine for satellite-based land surface temperature.
Data is atmospherically corrected and processed using a physics-based Temperature and Emissivity Separation algorithm.
Distributed in Cloud Optimized GeoTIFF (COG) format, facilitating cloud-based analysis.
Cross-platform presence on NASA Earthdata indicates established importance and accessibility.
Limitations
Metadata completeness is low; specific column names, row counts, file size, and license information are not provided in the input.
Instrument experienced data acquisition gaps due to anomalies with its primary and secondary mass storage units in 2018 and 2019.
Spatial coverage is limited to latitudes between 52° N and 52° S, excluding polar regions.
