Improved red-edge chlorophyll-a detection for Sentinel 2

open access: yesEcological Indicators, 2021
Chlorophyll-a (chl-a) concentration is an indicator of algal biomass. The Sentinel 2 platform offers greatly improved spatial resolution over other satellite platforms designed for water based chl-a retrievals and includes a “red-edge” band at 704 nm not

A Method for Landsat and Sentinel 2 (HLS) BRDF Normalization [PDF]

open access: yesRemote Sensing, 2019
The Harmonized Landsat/Sentinel-2 (HLS) project aims to generate a seamless surface reflectance product by combining observations from USGS/NASA Landsat-8 and ESA Sentinel-2 remote sensing satellites. These satellites’ sampling characteristics provide nearly constant observation geometry and low illumination variation through the scene.
