“…Solar radiation plays an important role in the distribution, composition, and productivity of ecosystems through photosynthetic activity (Satterlund and Means, 1978;Gates, 1980) and contributes to several parameters of the water balance (including air and soil heating, evapotranspiration, wind, snow and ice melt.) (Lebourgeois and Piedallu, 2005;Pierce et al, 2005). Many authors have sought to link solar radiation and the distribution or the productivity of plant species or communities (Franklin, 1998;Tappeiner et al, 1998;Zimmermann and Kienast, 1999;Meentemeyer et al, 2001;Dirnbock et al, 2003).…”

“…Measuring long-term solar radiation directly on plots is unrealistic over large areas, due to the number of plots necessary to establish relevant distribution models (Coudun and Gegout, 2006a). Few ground meteorological stations record these data, which are among the climatological values least frequently measured (Pierce et al, 2005;Yang et al, 2006).…”

ABSTRACT:The aim of this paper is to explore possibilities of application of digital elevation model for mapping vegetation tiers (altitudinal vegetation zones). Linear models were used to investigate the relationship between vegetation tiers and variables derived from a digital elevation model -elevation and potential global radiation. The model was based on a sample of 138 plots located from the 2 nd to the 5 th vegetation tier. Potential global radiation was computed in r.sun module in geographic information system GRASS. The final model explained 84% of data variability and employed variables were found to be sufficient for modelling vegetation tiers in the study area. Applied methodology could be used to increase the accuracy and efficiency of mapping vegetation tiers, especially in areas where such task is considered difficult (e.g. agricultural landscape).

“…Both DNI and DIF are rarely included in predictions made with numerical weather prediction (NWP) models. However, they are necessary in multiple applications such as those requiring a precise representation of surface solar radiation or solar energy applications (Geiger, 1965;Hay, 1993;Whiteman, 2000;Gu et al, 2002;Oliphant et al, 2003;Pierce et al, 2005;Stoffel et al, 2010;Kleissl, 2013).…”

Abstract. Broadband short-wave (SW) surface direct and diffuse irradiances are not typically within the set of output variables produced by numerical weather prediction (NWP) models. However, they are frequently requested for solar energy applications. In order to compute them, a detailed representation of the aerosol optical properties is important. Nonetheless, NWP models typically oversimplify aerosol representation or even neglect their effect. In this work, a flexible method to account for the SW aerosol optical properties in the computation of broadband SW surface direct and diffuse irradiances is presented. It only requires aerosol optical depth at 0.55 µm and knowledge of the type of predominant aerosol. Other parameters needed to consider spectral aerosol extinction, namely, Angström exponent, aerosol single-scattering albedo and aerosol asymmetry factor, are parameterized. The parameterization has been tested using the Rapid Radiative Transfer Model for climate and weather models (RRTMG) SW scheme of the Weather Research and Forecasting (WRF) NWP model for data over the continental US. In principle, it can be adapted to any other SW radiative transfer band model. It has been verified against a control experiment and using data from five radiometric stations in the contiguous US. The control experiment consisted of a clear-sky evaluation of the RRTMG solar radiation estimates obtained in WRF when RRTMG is driven with ground-observed aerosol optical properties. Overall, the verification has shown satisfactory results for both broadband SW surface direct and diffuse irradiances. The parameterization has proven effective in significantly reducing the prediction error and constraining the seasonal bias in clearsky conditions to within the typical observational error expected in well maintained radiometers.
