April 1, 2020- Landsat 8 Provisional Aquatic Reflectance Science Product Now Available

The USGS has released an on-demand Landsat 8 Provisional Aquatic Reflectance Science Product that will be useful in monitoring water quality, mapping chlorophyll concentrations, and measuring the inherent optical properties of water.

The Aquatic Reflectance product measures the spectral distribution of visible solar-reflected radiation upwelling from the upper water column and is derived from Landsat Collection 1 Level-1 reflective bands. The product’s 30 meter spatial resolution  provides the aquatic remote sensing community the capability to map optically active components across inland and near-shore water bodies.

The provisional Aquatic Reflectance science product is currently available for Landsat 8 Operational Land Imager (OLI) acquistions only (2013-present) through the USGS EROS Center Science Processing Architecture (ESPA) on-demand interface.

For more information please visit the Landsat Provisional Aquatic Reflectance web page.

This provisional Aquatic Reflectance product belongs to a suite of USGS research-quality, applications-ready, Landsat-derived science products aimed at reducing the burden of data processing for the user community.
