Detecting high-temperature anomalies from Sentinel-2 MSI images

ISPRS Journal of Photogrammetry and Remote Sensing, 2021
Abstract High-temperature anomalies (HTAs) of the earth's surface, such as fires, volcanic activities, and industrial heat sources, have a profound impact on Earth's system. Sentinel-2 Multispectral Instrument (MSI) provides spatially-specific information for precisely measuring the location and extent of HTAs at a fine scale. However, detecting HTAs

Automatic Extraction of Sargassum Features From Sentinel-2 MSI Images

IEEE Transactions on Geoscience and Remote Sensing, 2021
Frequent Sargassum beaching in the Caribbean Sea and other regions has caused severe problems for local environments and economies. Although coarse-resolution satellite instruments can provide large-scale Sargassum distributions, their use is problematic in nearshore waters that are directly relevant to local communities.

Evaluatiing the NDLI's Performance for Identifying Water Surface Using Sentinel-2 MSI Data

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
Land cover and land use (LULC) are the key determinant factors that influence the regional climate. In this study, we present LULC classification for the Taipei City, Taiwan based on Sentinel-2B image acquired in 2018. A recently-proposed Nomalized Difference Laten Heat Index (NDLI) and Nomalized Difference Vegetation Index (NDVI) are ultilized and ...

Intercomparison of Landsat OLI and Sentinel 2 MSI performance

For Landsat 8 and Landsat 9 (L8 and L9), the radiometric stability of the Operational Land Imager (OLI) is monitored using two solar diffusers, three sets of stimulation lamps, and regular lunar collects. Consistent response to the multiple calibrators provides high confidence in the radiometric characterization of the imagers over time and calibration
