Page Summary
-
The ECOSTRESS Tiled Ancillary NDVI and Albedo (ECO_L2T_STARS) V002 dataset provides NDVI and albedo data at a 70m spatial resolution from 2018-07-09 to 2025-10-09 with a daily cadence.
-
This dataset is created by fusing VIIRS and HLS data using the STARS algorithm and is useful for understanding plant water needs and stress.
-
The dataset includes bands for NDVI and albedo, along with their uncertainty, and is freely accessible from the LP DAAC NASA.
-
The data is available through Google Earth Engine for scientific analysis and visualization.

Description
The ECOSTRESS Tiled Ancillary NDVI and Albedo (ECO_L2T_STARS) V002 dataset provides Normalized Difference Vegetation Index (NDVI) and albedo data at a 70m spatial resolution. This ancillary product, essential for understanding plant water needs and stress, is created through a data fusion process that combines Visible Infrared Imaging Radiometer Suite (VIIRS) and Harmonized Landsat Sentinel (HLS) data. The fusion is performed using the STARS algorithm, a Bayesian timeseries methodology, to align the data with daytime ECOSTRESS overpasses. This product is only generated for corresponding ECOSTRESS Land Surface Temperature and Emissivity tiles.
