The retreats of the planet’s tropical glaciers are natural indicators variation precipitation, temperature, and other variables. Alto Santa sub-basin sources freshwater storage for consumptive non-consumptive use different sectors. As a result climatic variations, it is essential to analyze dynamics snow cover area (SCA). methodology consisted processing 6578 MODIS Snow Cover MOD10A1 product im...

Abstract In recent decades, glaciers outside Greenland and Antarctica have shown increasingly rapid rates of mass loss retreat the ice front, which is associated with climatic oceanic warming. Due to their maritime location, Icelandic are sensitive short-term climate fluctuations over last decade. this study, historical maps (1941–1949) US Army Map Service (AMS series C762) optical satellite im...

Glaciers are highly sensitive to climate change and undergoing significant changes in mid-latitudes. In this study, we analyzed the spatiotemporal of typical glaciers their responses period 1990–2015 4 different mountainous sub-regions Xinjiang Uygur Autonomous Region Northwest China: Bogda Peak Karlik Mountain Tianshan Mountains; Yinsugaiti Glacier sub-region Karakorum Youyi Altay Mountains. T...

Glacier and snow are sensitive indicators of regional climate variability. In the early 21st century, glaciers in West Kunlun Pamir regions showed stable or even slightly positive mass budgets, this is anomalous a worldwide context glacier recession. We studied evolution cover to understand whether it could explain area. study, we used thresholding NDSI (Normalized Difference Snow Index) retrie...

Mapping invasive vegetation species in arid regions is a critical task for managing water resources and understanding threats to ecosystem services. Traditional remote sensing platforms, such as Landsat MODIS, are ill-suited distinguishing native non-native due their large pixels compared plant sizes. Unmanned aircraft systems, or UAS, offer the potential capture high spatial resolution imagery...

Advanced Microwave Scanning Radiometer 2 (AMSR2) brightness temperature (TB) observations have long been utilized for snow depth (SD) estimation. However, the traditional approaches which are based on ‘point-to-point’ predictions ignore spatial heterogeneity within a AMSR2 pixel and limited by coarse resolution of sensor. To solve these problems, novel deep ‘area-to-point’ SD estimation model, ...

<p>Sandy areas are the main problem in regions of arid and semi-arid climate world that threaten urban life, buildings, agricultural, even human health. Remote sensing is one technologies can be used as an effective tool dynamic features study sandy sand accumulations. In this study, two new indices were developed to separate from non-sandy areas. The first called Normalized Differential ...
