Measuring centimeter-scale and smaller surface changes by satellite-based systems on the periglacial terrains and permafrost zones of the northern hemisphere is an ongoing challenge. We are investigating this challenge by using data from the NASA Ice, Cloud, and land Elevation Satellite Geoscience Laser Altimeter System (ICESat GLAS) and the JAXA Advanced Land Observing Satellite Phased Array t...

Reference evapotranspiration (ET0) is a crucial parameter for hydrological modeling, land-atmospheric interaction investigations and agricultural irrigation management. This study investigated changes in ET0 and attributed those changes to climate variations in a coastal area (Zhejiang province) of China by a numerical experiment method. The results indicated that annual ET0 increased significa...

In the past, current-distance spectroscopy has been widely applied to determine variations of the work function at surfaces. While for homogeneous sample areas this technique is commonly accepted to yield at least qualitative results, its applicability to atomic-scale variations has not been proven neither right nor wrong. Here we benchmark measurements of the current-distance decay constant ag...

We consider the numerical approximation of the shallow–water equations with non–flat topography. We introduce a new topography discretization that makes all schemes to be well–balanced and robust. At the discrepancy with the well–known hydrostatic reconstruction, the proposed numerical procedure does not involve any cut–off. Moreover, the obtained scheme is able to deal with dry areas. Several ...

A key factor in the implementation of productive and sustainable cultivation procedures is the frequent and area-wide monitoring of cropland and grassland. In particular, attention is focused on assessing the actual status, identifying basic trends and mitigating major threats with respect to land-use intensity and its changes in agricultural and semi-natural areas. Here, multi-seasonal analyse...

Volume 1, The Earth system: physical and chemical dimensions of global environmental change, pp 557–579 Ocean circulation is one of the major elements of climate, moving heat, freshwater, nutrients and dissolved gases. Ocean circulation at the largest spatial scales and long time scales contains many elements that are in common in the different oceans. Understanding the processes that drive the...

Introduction: Lobate debris aprons (LDA) (Fig. 1) surround steep escarpments such as the walls of isolated plateaus and massifs in the northern and southern mid-latitudes (~30 to 50) on Mars and are Middle to Late Amazonian in age [1]. Much evidence supports the formation of these features by flow of ice and debris in a manner similar to glacial systems on Earth [1-9]. Additional evidence has...

Abstract Dust storms may remarkably degrade the imaging quality of Martian orbiters and delay progress mapping global topography geomorphology. To address this issue, paper presents an approach that reuses image dehazing knowledge obtained on Earth to resolve dust-removal problem Mars. In approach, we collect remote-sensing images captured by Tianwen-1 manually select hundreds clean dusty image...
