Avaliação de dados meteorológicos obtidos por duas estações meteorológicas automatizadas.

Abstract

The objective of this study was the evaluation of Davis Instruments and Campbell Scientific automated weather stations, attempting to detect possible differences between both readings and estimatives. The meteorological data studied were the following: air temperature, air humidity, wind speed, and global solar radiation. The Penman-Monteith reference method of evapotranspiration was evaluated daily. The weather stations were set up in an experimental area of the Rural Engineering Department- FACV/UNESP, São Paulo State University of Jaboticabal. The data was collected daily and statistically analyzed by means of linear regression analysis. The results of this study show that air temperature and relative air humidity in both stations were similar. The daily estimatives of the reference method of evapotranspiration of both stations did not present acceptable differences.
