Performance of GLASS and MODIS Satellite Albedo Products in Diagnosing Albedo Variations during Different Time Scales and Special Weather Conditions in the Tibetan Plateau

Remote Sensing, 2020
Surface albedo is a crucial parameter in accurately and quantitatively estimating energy and water budget on the Tibetan Plateau (TP) and is also one of the largest radiative uncertainties in land surface modelling attempts.

Linking glacier annual mass balance and glacier albedo retrieved from MODIS data [PDF]

The Cryosphere, 2012
Albedo is one of the variables controlling the mass balance of temperate glaciers. Multispectral imagers, such as MODerate Imaging Spectroradiometer (MODIS) on board the TERRA and AQUA satellites, provide a means to monitor glacier surface albedo.

Urban Heat Island in the Eastern Mediterranean and Middle East: Multi‐City Approach in Regional Climate Modelling

International Journal of Climatology, EarlyView.
This study presents that the WRF model, coupled with bulk urban parameterization, effectively captures the summer urban heat island (UHI) patterns across the Eastern Mediterranean and Middle East, showing stronger night‐time surface UHIs (5°C–6°C) and daytime surface cool islands (up to 12.5°C).

Upcycling orange by‐product: phenolic bioaccessibility and technological features of jelly candies enriched with hydroalcoholic and enzymatic extracts

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Phenolic extracts are recognized for their health‐promoting properties, although some physicochemical characteristics limit their food applications. The present study aimed to valorize orange juice by‐products through enzymatic and hydroalcoholic extraction to obtain flavonoid ingredients and to evaluate their application in pectin ...

Land Surface Albedo Estimation from Chinese HJ Satellite Data Based on the Direct Estimation Approach

Remote Sensing, 2015
Monitoring surface albedo at medium-to-fine resolution (<100 m) has become increasingly important for medium-to-fine scale applications and coarse-resolution data evaluation.

Evaporation du sol nu en zone semi-aride et en conditions hivernales. Relations avec l'albédo et la température de la surface du sol [PDF]

, 1979
L'évaporation d'un sol nu dans le Sud Tunisien au mois de novembre, est mesurée après une pluie, ainsi que son albédo, sa température de surface et celle d'une parcelle maintenue humide par irrigation.

Forbs in Viking lands: the effect of disturbing dominant graminoids on recruitment in tundra grasslands

Oikos, EarlyView.
Grasslands, by definition, are dominated by graminoids. Nevertheless, forbs also make up a substantial part of vascular plant diversity in grasslands and are important resources of mammalian herbivores. However, forb recruitment is constrained by successful dominant graminoids, limiting access to safe sites for germination.

Die Arktis bei 2,7 Grad globaler Erwärmung: Schwindende Landschaften

Physik in unserer Zeit, EarlyView.
Eine dicke Eisschicht auf dem Ozean, hunderte Meter tief gefrorener Boden und ein über 3 000 m hoher Eisschild – diese einzigartige Landschaft wird es vermutlich so in Zukunft nicht mehr geben. Eine globale Erwärmung von 2,7 °C, auf die wir aktuell zusteuern, würde die Arktis bis zur Unkenntlichkeit verändern.

Subsurface Investigations of Cryo‐Hydrogeological Features in a High Arctic Catchment Under Transition

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT In this study, the internal structure and seasonal variations of cryo‐hydrogeological features were investigated in the Fuglebekken catchment, located near the Polish Polar Station Hornsund in Svalbard. Over a few years, rising air temperatures and intensified water circulation have significantly altered the distribution, extent, and state of ...
