Improving Chlorophyll-A Estimation From Sentinel-2 (MSI) in the Barents Sea Using Machine Learning [PDF]
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 This article addresses methodologies for remote sensing of ocean Chlorophyll-a (Chl-a), with emphasis on the Barents Sea. We aim at improving the monitoring capacity by integrating in situ Chl-a observations and optical remote sensing to locally train machine learning (ML) models.

Use of Sentinel-2 MSI data to monitor crop irrigation in Mediterranean areas
International Journal of Applied Earth Observation and Geoinformation, 2020 The availability of accurate information on the water consumed for crop irrigation is of vital importance to support compatible and sustainable environmental policies in arid and semi-arid regions. This has promoted several studies about the use of remote sensing data to monitor irrigated croplands, which are mostly based on statistical classification ...

Mapping Mining Areas in the Brazilian Amazon Using MSI/Sentinel-2 Imagery (2017) [PDF]
Remote Sensing, 2018 Although mining plays an important role for the economy of the Amazon, little is known about its attributes such as area, type, scale, and current status as well as socio/environmental impacts. Therefore, we first propose a low time-consuming and high detection accuracy method for mapping the current mining areas within 13 regions of the Brazilian ...
