Abstract

Here we present the database of water surface reflectance from 1985 to 2023 for global coastal river and estuaries. This database contains the Landsat Collection 2 Surface reflectance of TM, ETM+, OLI and OLI-2. To build the database, we used the estuary shapefile from Alder (2003) and river reach shapefile from the Surface Water and Ocean Topography (SWOT) Mission River Database (Altenau et al., 2021) within 250 km of the coastline. In total, we have pointed grid (234,868 points) within 1080 estuary boundary, and 113,080 coastal river reaches. Then we used the water masking algorithm, described in Prum et al. (2024) and Gardner et al. (2021) to pull the median surface reflectance of Landsat Collection 2 data. The harmonization of TM, ETM+, OLI and OLI-2 model is provided based on method from Prum et al. (under review) for harmonization coefficient model.

This dataset is currently under embargo and will available for public assess after peer review process of Prum et al. (under review) completed.
