Resumo: | This work studies the month average of daily global solar radiation, daily relative global solar radiation, daily sunshine duration and daily relative sunshine duration, for the conditions in Goiânia county and surrounding counties, Goiás — Brazil (latitude: 16°41'S, longitude: 49°17’W GRW, and altitude: 680.00m). It's observed that: a) global solar radiation is maximum in October and minimum in July; b) relative global solar radiation is maximum in August and minimum in November; c) sunshine duration is maximum in June and minimum in November; d) relative sunshine duration is maximum in June and minimum in November. Correlation between the month average of daily relative global solar radiation and of daily sunshine duration allowed to conclude the linear equation: Kg = Ka (0.49 n/N), where the letters mean: Kg = daily global radiation (ly/day); Ka = daily solar radiation on the top of atmosphere (ly/day); n = daily duration of sunshine (hr/day); N = daily maximum duration of sunshine (hr/day). The methodology adopted was the one proposed by PRESCOTT (1940) and PENMAM (1948), as cited by BLACK et alii (1954), in order to estimate parameters ";a"; and “b”, in the equation Kg/Ka = a + b (n/N), which correlates the sunshine ratio (n/N) to the relative solar, radiation (Kg/Ka) by linear regression analysis. The equation found showed a correlation coefficient which was equal to 0.95 with significance at 0.1% probability level. |

CONTRIBUTION TO THE STUDY OF GLOBAL RADIATION AND INSOLATION IN THE MATO GROSSO DE GOIÁS MICROREGIONCONTRIBUIÇÃO AO ESTUDO DA RADIAÇÃO GLOBAL E DA INSOLAÇÃO NA MICRO-REGIÃO DO MATO GROSSO DE GOIÁS This work studies the month average of daily global solar radiation, daily relative global solar radiation, daily sunshine duration and daily relative sunshine duration, for the conditions in Goiânia county and surrounding counties, Goiás — Brazil (latitude: 16°41'S, longitude: 49°17’W GRW, and altitude: 680.00m). It's observed that: a) global solar radiation is maximum in October and minimum in July; b) relative global solar radiation is maximum in August and minimum in November; c) sunshine duration is maximum in June and minimum in November; d) relative sunshine duration is maximum in June and minimum in November. Correlation between the month average of daily relative global solar radiation and of daily sunshine duration allowed to conclude the linear equation: Kg = Ka (0.49 n/N), where the letters mean: Kg = daily global radiation (ly/day); Ka = daily solar radiation on the top of atmosphere (ly/day); n = daily duration of sunshine (hr/day); N = daily maximum duration of sunshine (hr/day).

The equation found showed a correlation coefficient which was equal to 0.95 with significance at 0.1% probability level. O presente trabalho analisa as médias mensais de radiação solar global diária, radiação solar global relativa diária, insolação diária do Mato Grosso de Goiás. Os dados utilizados foram obtidos na Estação Evaporimétrica de lª classe, Modelo DNAEE — CPRM, localizada na Escola de Agronomia — UFG, latitude: 16°41'S, longitude 49°17'W GRW, altitude 680,00m e na Estação do Centro Nacional de Pesquisa de Arroz e Feijão - EMBRAPA, Goiânia — GO. A correlação entre as médias mensais da radiação solar global relativa diária e da insolação relativa diária permitiu concluir que a equação linear para a região do Mato Grosso de Goiás é o seguinte: Kg = Ka (0,27 + 0,49 n/N), onde, Kg = radiação solar global diária (ly/dia), Ka = radiação solar global diária, no topo da atmosfera (ly/dia), n = insolação diária, N = insolação máxima diária (h/dia). A metodologia adotada foi a proposta por PRESCOTT(1940) e PANMAN (1948), citada por BLACK et al (1954) para estimativa dos parâmetros a e b. A equação linear determinada mostrou um coeficiente de correlação igual a 0,95, e significância de 0,l% de probabilidade, sendo sua utilização recomendada para estimativas de valores médios de radiação solar recebida na superfície da terra, em período de cinco ou mais dias.Escola de Agronomia - Universidade Federal de Goiás2007-11-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/2423Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 12, n. 1, Jan./Dec. 1982; 55-75Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 12, n. 1, jan./dez. 1982; 55-75Pesquisa Agropecuária Tropical; v. 12, n. 1, jan./dez. 1982; 55-751983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/2423/2387Lobato, Olivar José da Silva M.Lobato, Engler José VidigalGonçalves, Vicente Antônioinfo:eu-repo/semantics/openAccess2020-02-26T23:51:32Zoai:ojs.revistas.ufg.br:article/2423Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:08.801766Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
