Global-RSWQmonitor

Global water quality mapping and monitoring

Mission

Monitoring inland and coastal water quality at large spatial scales and near-real-time frequency

Global-RSWQmonitor is an interactive Google Earth Engine application for global water quality mapping and monitoring using Landsat-8/9 and Sentinel-2 observations. The platform integrates ACOLITE-based atmospheric correction and retrieves chlorophyll-a, turbidity, total suspended solids, colored dissolved organic matter, and Secchi disk depth using empirical models calibrated with the global GLORIA in-situ database.
