Application of Sentinel 3 OLCI for chl-a retrieval over small inland water targets: Successes and challenges
TL;DR: In this article, four full atmospheric correction methods are assessed over four inland water reservoirs in South Africa, along with a suite of red/NIR based semi-analytic and band difference models for chl-a estimation which were applied to both full and partial atmospherically corrected data.
