“…Air temperature, sunshine fraction, and precipitation are the meteorological parameters with greater abundance and spatial distribution in databases; therefore, they are the most commonly adopted in the simplified models used to estimate global radiation for different climatic regions and/or temporal scales (Besharat et al, 2013;Bojanowski et al, 2013;Veeraboina & Guduri, 2014;Yacef et al, 2014;Dumas et al, 2015). However, the accuracy of these models may vary when applied in different locations, requiring local/regional calibrations of the parameterized coefficients (Teke et al, 2015;Huber et al, 2016).…”

“…In this context, the high cost of measuring solar irradiation with a pyranometer and the scarcity of long, reliable datasets for specific locations has encouraged the use of simplified estimators, including models based on air temperature, air humidity, precipitation, sky cover (clouds), sunshine fraction, linear regression, geostationary satellite data, stochastic models, artificial neural networks, among others (Gueymard & Myers, 2009;Antonanzas-Torres et al, 2013;Bojanowski et al, 2013;Veeraboina & Guduri, 2014;Yacef et al, 2014;Dumas et al, 2015;Teke et al, 2015).…”

-The objective of this work was to estimate the global radiation by simplified models for the state of Mato Grosso, Brazil. The parameterized coefficients of 15 simplified models were regionally calibrated to estimate the daily global radiation, based only on air temperature, using data from 28 automatic weather stations (AWS) of the network of the Brazilian Meteorology Institute, distributed throughout the different biomes of the state of Mato Grosso. The simplified models are mostly derived from the Hargreaves and Bristow & Campbell methods, with different parameterized coefficients to be calibrated. The coefficient of determination (R 2 ), the mean bias error (MBE), the root mean square error (RMSE), and Willmott's d index were used to evaluate statistical performance. For the recommendation of models per station and/or biome, the models were rated numerically Index terms: air temperature, Amazon, Cerrado, parameterized coefficients, solar radiation.

Os coeficientes parametrizados de 15 modelos simplificados foram regionalmente calibrados para estimativa da radiação global diária, com base apenas na temperatura do ar, a partir de dados de 28 estações meteorológicas automáticas (EMAs) da rede do Instituto Nacional de Meteorologia, distribuídas nos diferentes biomas do Estado de Mato Grosso. Os modelos simplificados avaliados foram derivados principalmente dos métodos de Hargreaves e Bristow & Campbell, com diferentes coeficientes parametrizados a serem calibrados.

“…Horizontally placed collectors of LF observes higher cosine losses causing higher optical losses. Cosine losses typically occurs if the surface is not normal to the sun, thus reduce the solar irradiance to the surface [36,39]. Figure 7 shows that during early morning and late afternoon optical efficiency is reduced due to the shading of a LF adjacent collector array.…”

Abstract:Solar Tower thermal (ST), Parabolic Trough thermal (PT), Linear Fresnel thermal (LF) and Solar PV are discussed in the context of suitability for hybridization with biomass in Europe.Technical, economical and climate data have been compared to identify the key drivers of technology selection in setting up large scale solar-biomass hybrid power plants. The sole solar-biomass hybrid power plant is currently in operation in Spain uses PT technology due to its performance characteristics, comparatively easy installation process compared to ST and relatively higher heat and optical gain than LF. The climate condition in the EU shows that the region within average yearly direct normal irradiance (DNI) 1400 -1800 kWh/m 2 can be useful for CSP hybridization as the distribution periods of high intensity of DNI of solar energy justify integrating biomass. Of the three concentrated solar power (CSP) technologies, ST provides the best overall efficiency for combined heat and power (CHP) generation.

“…La radiación solar, precipitación y temperatura fueron identificados por Nemani et al (2003) como los factores climáticos potencialmente limitantes del crecimiento vegetal, siendo su influencia de mayor o menor grado dependiendo de la región de cultivo (Figura 1) (Bojanowski et al, 2013). Por ello la producción agrícola puede llegar a verse fuertemente afectada por el clima, así como por cambios en la concentración de gases de efecto invernadero.…”

“…Fue por esto que, sin recurrir a la validación cruzada y haciendo uso del conjunto de valores predichos y observados, se decidió utilizar como segundo indicador el propuesto por Li et al (2011), utilizado además en otras investigaciones (Bojanowski et al 2013;Bellocchi et al 2010). Este indicador es el valor relativo del RMSE (RRMSE, de las siglas en inglés Relative Root-Mean-Squared-Error), el cual elimina el efecto de las unidades de medida y por tanto no es sensible a los cambios en la unidad de medida o escala.…”
