Seasonal Net Shortwave Radiation of Bare Arable Land in Poland and Israel According to Roughness and Atmospheric Irradiance

Tillage of arable fields, using for instance a smoothing harrow, may increase the magnitude albedo such soil surfaces depending on location, sun’s illumination and atmospheric components. As these absorb less shortwave radiation compared to plowed soils, result is an cooling positive effect Earth’s climate. This paper follow-on previous study aimed at quantifying seasonal dynamics net reflected by bare air-dried land areas located in contrasting environments, i.e. Poland Israel. Soil tillage includes plow, disk harrow. Previous work concentrated estimate under clear-sky theoretical scenarios, whereas present deals with realistic atmosphere throughout year 2014. latter characterized observations Spinning Enhanced Visible Infrared Imager (SEVIRI) instrument board Meteosat Second Generation (MSG). The variations selected were assessed combining from Landsat 8 images digital maps use soil, plus model equations that calculate diurnal broadband blue-sky roughness inclusive. daily amount Israel time their spatial coverage largest was found be about 40–50% 10% lower, respectively, cloudy-sky conditions conditions.
