Resumo: The purpose of this work was to compare three methods for simulating data of photosynthetically active radiation and air temperature, using daily parameters of 17 stations of São Paulo State, Brazil. The simulation of those elements was carried out for de 1st and the 16th day of each month, through three cases: nonsymmetric triangular distribution; normal distribution truncated at 1.96 standard deviation; and bivaried normal distribution. The simulated data were evaluated through the tests of homogeneity of variance F and Bartlett, t test, agreement index of Willmott, angular coefficient of the straight line, the index of performance of Camargo and tack the normal distribution (uni-varied). The simulation using the bi-varied normal distribution is most appropriate for representing the climate variables.

A simulação foi realizada para o primeiro e o 16o dia de cada mês, conforme: a distribuição normal truncada a mais ou menos 1,96 de desvio-padrão; distribuição triangular assimétrica; e distribuição normal bivariada. As estimativas com os dados simulados foram comparadas com os respectivos parâmetros (obtidos com os dados observados), pelos testes de homogeneidade de variância F e Bartlett, teste t de comparação de médias, coeficiente de correlação de Pearson, índice de concordância de Willmott, índice de desempenho de Camargo, coeficiente angular e o teste de normalidade dos dados. A simulação pela distribuição normal bivariada é a mais adequada para representar as variáveis climáticas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMartin, Thomas NewtonStorck, LindolfoNeto, Durval Dourado2007-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7687Pesquisa Agropecuaria Brasileira; v.42, n.9, set. 2007; 1211-1219Pesquisa Agropecuária Brasileira; v.42, n.9, set. 2007; 1211-12191678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7687/4606info:eu-repo/semantics/openAccess2010-09-29T12:13:20Zoai:ojs.seer.sct.embrapa.br:article/7687Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-09-29T12:13:20Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
