Stability in time and consistency between atmospheric corrections: Assessing the reliability of Sentinel-2 products for biodiversity monitoring in tropical forests [PDF]

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2022
Earth observation satellite imagery is increasingly accessible, and has become a key component for vegetation mapping and monitoring. Sentinel-2 satellites acquire optical images with five days’ revisit frequency, which is an important feature to ...

Sentinel-2 Global Surface Reflectance Level-2a Product Generated with Sen2Cor [PDF]

open access: yesIGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
Sen2Cor is a Level-2A processor designed to correct Sentinel-2 Level-1C products from the effects of the atmosphere in order to deliver a Level-2A surface reflectance product. ESA has been using Sen2Cor for systematic Level-2A processing of Sentinel-2 acquisitions over Europe since June 2017. It has since then been successfully integrated into Sentinel-

Evaluation of Sentinel-2A Surface Reflectance Derived Using Sen2Cor in North America

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2018
Surface reflectance can be derived from satellite measurements for the top of atmosphere and provides an important dataset for monitoring land change reliably. In this study, the Sentinel-2A surface reflectance was generated using the Sentinel-2 atmospheric correction (Sen2Cor) processor.

A Preliminary Analysis towards Detecting Floating Marine Macro Plastics Using an Index Developed for Sentinel 2 ACOLITE and Sen2Cor Images

open access: yesJouranal of Geomatics Surveying, 2022
The improper management of plastic waste has become a silent killer in the marine ecosystem. The scientific evidence of plastic accumulated in marine biota and entering the food web have urged quick actions against the plastic pollution. The plastic detection algorithms developed using satellite images can proclaim emission, transportation, weathering ...

Comparison of Cloud Cover Detection Algorithms on Sentinel–2 Images of the Amazon Tropical Forest

open access: yesRemote Sensing, 2020
Tropical forests regulate the global water and carbon cycles and also host most of the world’s biodiversity. Despite their importance, they are hard to survey due to their location, extent, and particularly, their cloud coverage.

High-resolution urban air quality monitoring using sentinel satellite images and low-cost ground-based sensor networks [PDF]

open access: yesE3S Web of Conferences, 2020
Satellite remote sensing aerosol monitoring products are readily available but limited to regional and global scales due to low spatial resolutions making them unsuitable for city-level monitoring. Freely available satellite images such as Sentinel -2 at

Closed-Form Method for Atmospheric Correction (CMAC) of Smallsat Data Using Scene Statistics

open access: yesApplied Sciences, 2023
High-cadence Earth observation smallsat images offer potential for near real-time global reconnaissance of all sunlit cloud-free locations. However, these data must be corrected to remove light-transmission effects from variable atmospheric aerosol that ...
