Cross-Country Assessment of H-SAF Snow Products by Sentinel-2 Imagery Validated against In-Situ Observations and Webcam Photography
Gaia Piazzi,Cemal Melih Tanis,Semih Kuter,Burak Simsek,Silvia Puca,Alexander Toniazzo,Matias Takala,Zuhal Akyürek,Simone Gabellani,Ali Nadir Arslan +9 more
TL;DR: In this article, the authors used high-resolution imagery collected by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) to assess moderate-resolution snow products, namely H10-Snow detection (SN-OBS-1) and H12-Effective snow cover (SN OBS-3) supplied by the Satellite Application Facility on Support to Operational Hydrology and Water Management (H-SAF) project.

A lightweight deep learning based cloud detection method for Sentinel-2A imagery fusing multi-scale spectral and spatial features
Jun Li,Zhaocong Wu,Zhongwen Hu,Canliang Jian,Shaojie Luo,Lichao Mou,Xiao Xiang Zhu,Matthieu Molinier +7 more
TL;DR: A lightweight network for cloud detection, fusing multiscale spectral and spatial features (CD-FM3SFs) and tailored for processing all spectral bands in Sentinel-2A images, which outperforms traditional cloud detection methods and state-of-the-art DL-based methods in both accuracy and speed.
Journal ArticleDOI
A Principal Component Based Haze Masking Method for Visible Images
TL;DR: A principal component (PC)-based haze masking (PCHM) method is developed for the masking of haze in visible remote sensing images covering land surfaces at middle latitudes and the quantitative assessments verify the superiority of the proposed method over the haze optimized transformation method for the production of binary haze masks.

A First Assessment of Canopy Cover Loss in Germany's Forests after the 2018-2020 Drought Years
Frank Thonfeld,Ursula Gessner,Stefanie Holzwarth,Jennifer Kriese,Emmanuel Da Ponte,Juliane Huth,Claudia Kuenzer +6 more
TL;DR: In this paper , the authors presented the first assessment of canopy cover loss in Germany for the period of January 2018-April 2021 using dense Sentinel-2 and Landsat-8 time-series data.
Journal ArticleDOI
Integrating age in the detection and mapping of incongruous patches in coffee (Coffea arabica) plantations using multi-temporal Landsat 8 NDVI anomalies
TL;DR: Accuracy assessment indicated that it was possible to separate incongruous and healthy patches using these anomalies and that using NDVI performed better than using LSWI for both global and age-adjusted mean anomalies.

A Landsat surface reflectance dataset for North America, 1990-2000
Jeffrey G. Masek,Eric Vermote,Nazmi Saleous,Robert E. Wolfe,Forrest G. Hall,Karl F. Huemmrich,Feng Gao,J. Kutler,Teng-Kui Lim +8 more
TL;DR: Initial comparisons with ground-based optical thickness measurements and simultaneously acquired MODIS imagery indicate comparable uncertainty in Landsat surface reflectance compared to the standard MODIS reflectance product.

Discriminating clear sky from clouds with MODIS
Steven A. Ackerman,Kathleen I. Strabala,W. Paul Menzel,Richard A. Frey,Christopher C. Moeller,Liam E. Gumley +5 more
TL;DR: The MODIS cloud mask algorithm as discussed by the authors uses several cloud detection tests to indicate a level of confidence that the MEDIS is observing clear skies, which is ancillary input to MEDIS land, ocean, and atmosphere science algorithms to suggest processing options.

Calculation of radiative fluxes from the surface to top of atmosphere based on ISCCP and other global data sets: Refinements of the radiative transfer model and the input data
TL;DR: Zhang et al. as discussed by the authors used a more advanced NASA Goddard Institute for Space Studies (GISS) radiative transfer model and improved ISCCP cloud climatology and ancillary data sets.

Spectral signature of alpine snow cover from the Landsat Thematic Mapper.
Jeff Dozier,Jeff Dozier +1 more
TL;DR: In this article, the spectral signatures of the Landsat TM images of the Sierra Nevada were analyzed to distinguish several classes of snow from other surface covers, and a number of TM images were used for automatic analysis of alpine snow cover.
