rslearn.data_sources.planetary_computer.Sentinel3SlstrLST

Sentinel-3 SLSTR Level-2 Land Surface Temperature (LST) data on Microsoft Planetary Computer. This dataset is provided as netCDF swaths; the data source uses the lst-in asset for measurements and the slstr-geodetic-in asset for geolocation. During ingestion it interpolates the swath onto a regular lat/lon grid using linear weights (this is an approximation; for precise geolocation you may need a custom workflow).
