Abstract (English): Knowledge of the periods when the meteorological conditions are favorable for agricultural spraying is important in agricultural planning, particularly in fleet dimensioning. This study aimed to determine, on a temporal scale, favorable weather conditions for agricultural spraying in Rio Grande do Sul State, Brazil. In addition, the times and months of the year that have the most and least suitable conditions for agricultural spraying were investigated, as well as the meteorological conditions that are frequently limiting and their relationships with the geographic coordinates and altitude of the location. Hourly data from automatic weather stations in 12 locations were collected, totaling 56,500 days and 1,356,009 hourly observations. Wind speeds greater than 3 km h-1 and less than 10 km h-1, air temperatures up to 30 °C, and relative air humidity above 55% were considered favorable. The data were released after descriptive analysis considering the registered frequency and mean. Altitude showed a moderate negative correlation with wind speed favorability. Air temperature was the meteorological element with the greatest favorability for agricultural spraying in the Rio Grande do Sul State, whereas wind speed was the most limiting meteorological element. There were no differences in favorability between the months of the year. The most favorable times were from 6:00 p.m. to 11:00 a.m. and the most unfavorable from 12:00 p.m. to 5:00 p.m. Considering the condition in which air temperature, wind speed, and relative air humidity were adequate for agricultural spraying simultaneously in the Rio Grande do Sul State, 43.2% of the periods were favorable.

Abstract (Portuguese): O conhecimento dos momentos em que as condições meteorológicas são favoráveis à pulverização agrícola é importante no planejamento agrícola, principalmente para o dimensionamento da frota. Este estudo teve como objetivo determinar, em escala temporal, as condições climáticas favoráveis à pulverização agrícola no Estado do Rio Grande do Sul, assim como as épocas e meses do ano com melhores e piores condições, o elemento meteorológico mais limitante e suas relações com as coordenadas geográficas e a altitude do local. Foram utilizados dados horários de estações meteorológicas automáticas de 12 locais, perfazendo um total de 56.500 dias e 1.356.009 observações horárias. Foram considerados favoráveis os valores de velocidade do vento acima de 3 km h-1 e abaixo de 10 km h-1, temperatura do ar = 30 °C e umidade relativa do ar maior que 55%. Os dados foram expostos após à análise descritiva considerando a frequência e a média registrada. A altitude apresentou correlação negativa moderada com a velocidade do vento. A temperatura do ar é o elemento meteorológico com maior favorabilidade para pulverizações agrícolas no Rio Grande do Sul. A velocidade do vento é o elemento meteorológico mais limitante. Não houve diferença de favorabilidade entre os meses do ano. Os horários mais favoráveis ocorreram das 18:00 às 11:00 h e os mais desfavoráveis das 12:00 às 17:00 h. Considerando a condição em que a temperatura do ar, velocidade do vento e umidade relativa do ar foram simultaneamente adequadas para a pulverização agrícola no Rio Grande do Sul, 43,2% dos momentos foram favoráveis.
