SiteSR: AquaMatch Landsat Collection 2 surface reflectance and surface temperature datasets for remote-sensing visible Water Quality Portal and National Water Information System sites in the United States and Territories, 1983-2024

This dataset, “siteSR: AquaMatch Landsat Collection 2 surface reflectance and surface
temperature datasets for remote-sensing visible Water Quality Portal and National Water
Information System sites in the United States and territories, 1983-2024”, is a component of
an update to AquaSat (Ross et al., 2019): AquaSat version 2 (“v2”). The overarching purpose
of AquaSat v2 is to emphasize the individual parts of the AquaSat pipeline that make up the
matchups between satellite and in situ measurements. This data release focuses on the
Landsat Collection 2 Surface Reflectance and Surface Tempearture record for remote-sensing
visible sites (n = 395,307) from the Water Quality Portal, National Water Information
System, AquaMatch harmonized chlorophyll a (Brousil, et al. 2024), Secchi disc depth (De La
Torre, et al. 2025), dissolved organic carbon (Brousil, et al. 2025), and total suspended
solids (Brousil, et al. 2025) data products in surface water from the Water Quality Portal.
Landsat data were acquired using Google Earth Engine (Gorelick, 2017) in Python programming
language and filtered to meet minimum quality thresholds in R programming language.
