“…The knowledge of seasonal and temporal variations allow its use in studies on evapotranspiration, optimization of water demand in irrigation, crop forecasting, agricultural planning, climate change, development of energy technology systems (thermal and photovoltaic), food preservation, buildings and ambiance, among others (Antonanzas-Torres et al, 2013;Dumas 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).…”

“…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).…”

-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.

“…O heliográfico é o instrumento para medir as horas de brilho solar, sendo um instrumento de fácil aquisição e que necessita de pouca manutenção. O conhecimento das horas de brilho solar de uma região é importante para o correto desenvolvimento do turismo, do planejamento urbano, de políticas relacionadas à saúde, além de contribuir para a adaptabilidade de espécies animais e vegetais (MOTA, 1975;VAREJÃO-SILVA, 2006 -SHEHRI, 2014;YAO et al, 2014;DUMAS et al, 2015;NWOKOLO;OGBULEZIE, 2017).

RESUMO: A equação de Angstrom continua sendo a relação mais usada para se estimar a irradiação solar global média diária a partir das horas de brilho solar, em localidades onde a medição não seja contínua ou os equipamentos não estejam disponíveis. O objetivo deste trabalho foi de apresentar a evolução das medidas de irradiação solar e das horas de brilho solar e determinar os coeficientes de Angstrom para estimativa da irradiação solar global na cidade de Maputo. A média da irradiação solar global na cidade de Maputo foi de 17,96 MJ/m² e as horas de brilho solar foram de 7,8 horas. Os coeficientes "a" e "b" do modelo anual para estimativa da irradiação solar global na cidade de Maputo são 0,23 e 0,49 respetivamente.Palavras-chaves: brilho solar, estimativa irradiação solar global, modelo de angstrom. ABSTRACT:The Angstrom equation continues to be the most used relation to estimate the daily average global solar irradiation from sunshine, in places where measurement is not continuous or equipment is not available. The aim of this work was to present the evolution of solar radiation and sunshine measurements and to determine the Angstrom coefficients to estimate global solar irradiation in the city of Maputo. The average of the global solar irradiance in the city of Maputo was 17.96 MJ/m² and sunshine average was 7.8 hours. The coefficients "a" and "b" of the annual model for estimation of global solar irradiation in the city of Maputo were 0.23 and 0.49, respectively.

We utilize the multiple linear regression method to analyse meteorological data for eight cities in Burkina Faso. A correlation between the monthly mean daily global solar radiation on a horizontal surface and five meteorological and geographical parameters, which are the mean daily extraterrestrial solar radiation intensity, the average daily ratio of sunshine duration, the mean daily relative humidity, the mean daily maximum air temperature, and the sine of the solar declination angle, was examined. A second correlation is established for the entire country, using, this time, the monthly mean global solar radiation on a horizontal surface and the following climatic variables: the average daily ratio of sunshine duration, the latitude, and the longitude. The results show that the coefficients of correlation vary between 0.96 and 0.99 depending on the station while the relative errors spread between −3.16% (Pô) and 3.65% (Dédougou). The maximum value of the RMSD which is 312.36 kJ/m2 is obtained at Dori, which receives the strongest radiation. For the entire cities, the values of the MBD are found to be in the acceptable margin.
