Reprocessing Timeline
In October 2022, ECOSTRESS released Collection 2, which includes an updated radiometric vicarious calibration, improved geolocation flagging, improved cloud mask, and improvements and additions to evapotranspiration (ET) models. The team has also made available the inputs that were used in the ET models, for full transparency. These include normalized difference vegetation index (NDVI), and albedo derived from a data fusion between VIIRS and harmonized Landsat-Sentinel (HLS), as well as reanalysis data resampled to ECOSTRESS spatial resolution.
Radiance, geolocation, land surface temperature & emissivity, and cloud products (level 1 and 2 products) have been available in Collection 2 since October 05, 2022. Higher level products (level 3 and 4) have been available in Collection 2 since January 18, 2024. The team continues to produce Collection 1 for Level 1 and 2 data products so that users can evaluate a consistent time series. Collection 1 will be discontinued as soon as Collection 2 reprocessing is complete (for level 1 and 2). Collection 1 ended for level 3 and 4 products on December 31, 2022, due to the changing MODIS orbit and changes in Landsat data accessibility. The Collection 1 data availability dates and Collection 2 reprocessing dates are listed in the table below:
