Exoplanet Terra Incognita

, 2018
Exoplanet surface imaging, cartography and the search for exolife are the next frontiers of planetology and astrophysics. Here we present an over-view of ideas and techniques to resolve albedo features on exoplanetary surfaces.

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 ...

Effect of Albedo Footprint Size on Relationships between Measured Albedo and Forest Attributes for Small Forest Plots

Remote Sensing
The albedo of boreal forests depends on the properties of the forest and is a key parameter for understanding the climate impact of forest management practices at high northern latitudes.

Exoplanet albedo spectra and colors as a function of planet phase, separation, and metallicity [PDF]

, 2010
First generation optical coronagraphic telescopes will obtain images of cool gas and ice giant exoplanets around nearby stars. The albedo spectra of exoplanets at planet-star separations larger than about 1 AU are dominated by reflected light to beyond 1

How well do the regional atmospheric and oceanic models describe the Antarctic sea ice albedo? [PDF]

The Cryosphere
We assessed how well regional climate models (HCLIM, MAR, RACMO), ocean models (MetROMS-UHel, NEMO), and ERA5 reanalysis simulate Antarctic sea ice albedo, snow, and ice thickness, using in situ data from field campaigns (ISPOL, Weddell Sea, in December ...

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.

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.

The albedo of snow for partially cloudy skies [PDF]

The input parameters of the model are atmospheric precipitable water, ozone content, turbidity, cloud optical thickness, size and shape of ice crystal of snow and surface pressure.

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.

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.
