Abstract. Surface downward shortwave radiation (DSR) and photosynthetically active (PAR) play critical roles in the Earth's surface processes. As main inputs of various ecological, hydrological, carbon, solar photovoltaic models, increasing requirements for high-spatiotemporal-resolution DSR PAR estimation with high accuracy have been observed recent years. However, few existing products satisf...

This article focuses on the short-term prediction algorithm for ice condensation highway pavement. Solar radiation, ground long wave and atmospheric inverse radiation are main factors affecting road surface temperature changes. According to principle of heat transfer, there is a balance relationship among these three factors. Therefore, based between radiations physical formula, this designs ic...

Upscaling instantaneous evapotranspiration retrieved at any specific time-of-day (ETi) to daily evapotranspiration (ETd) is a key challenge in mapping regional ET using polar orbiting sensors. Various studies have unanimously cited the shortwave incoming radiation (RS) to be the most robust reference variable explaining the ratio between ETd and ETi . This study aims to contribute in ETi upscal...

Most of the current coupled general circulation models show a strong warm bias in the eastern Tropical Atlantic. In this paper, various sensitivity experiments with the Kiel Climate Model (KCM) are described. A largely reduced warm bias and an improved seasonal cycle in the eastern Tropical Atlantic are simulated in one particular version of KCM. By comparing the stable and well-tested standard...

W eather and climate on Earth are determined by the amount and distribution of incoming radiation from the sun. For an equilibrium climate, OLR1 necessarily balances the incoming ASR, although there is a great deal of fascinating atmosphere, ocean, and land phenomena that couple the two. Incoming radiant energy may be scattered and reflected by clouds and aerosols or absorbed in the atmosphere....

During El Niño years, fires in tropical forests and peatlands in equatorial Asia create large regional smoke clouds. We characterized the sensitivity of these clouds to regional drought, and we investigated their effects on climate by using an atmospheric general circulation model. Satellite observations during 2000–2006 indicated that El Niño-induced regional drought led to increases in fire e...

The effects of air temperature, relative and specific humidity, wind speed, solar shortwave radiation, thermal longwave radiation, and rain on the performance of participants in the annual Stockholm Marathon from 1980 to 2008 were analysed statistically. The objective was to validate and extend previous studies by including data on finishing times of slower male and female runners and on the pe...

Abstract. Shortwave radiation penetrating beneath an ice-sheet surface can cause internal melting and the formation of a near-surface porous layer known as weathering crust, dynamic hydrological system that provides home to impurities microbial life. We develop mathematical model, incorporating thermodynamics population dynamics, for evolution such layers. The model accounts conservation mass e...
