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.

本数据集“siteSR：AquaMatch 美国及领地1983-2024年遥感可见水质门户（Water Quality Portal）与国家水信息系统（National Water Information System）站点的陆地卫星（Landsat）Collection 2地表反射率（surface reflectance）和地表温度（surface temperature）数据集”，是AquaSat（Ross等，2019）更新版本AquaSat v2的组成部分。AquaSat v2的总体目标是凸显构成卫星与原位测量（in situ measurements）匹配样本的AquaSat流程各环节。本次数据发布聚焦于来自水质门户、国家水信息系统的遥感可见站点（n = 395,307）的Landsat Collection 2地表反射率与地表温度记录，以及水质门户中地表水的AquaMatch协调叶绿素a（chlorophyll a）、赛氏盘透明度（Secchi disc depth）、溶解有机碳（dissolved organic carbon）和总悬浮固体（total suspended solids）数据产品。Landsat数据通过Python编程语言（Python programming language）调用谷歌地球引擎（Google Earth Engine，Gorelick，2017）获取，并在R编程语言（R programming language）中过滤以满足最低质量阈值要求。该数据产品的补充文档可访问：https://aquasat.github.io/AquaMatch_lakeSR/。
