                         stations networks, the data collected by remote sensors carried by 
                         orbital satellites is an alternative which should be taken into 
                         account, considering that the surface temperature is one of the 
                         most important data provided by them, due to its large utility in 
                         agricultural monitoring. This article compares the use of images 
                         from the satellite AVHRR/NOAA, in order to obtain the surface 
                         temperature, with the temperatures obtained by weather stations. 
                         The satellite images were processed, and by using four different 
                         equations it was obtained the surface temperature for each pixel. 
                         Based on the coordinates of each surface weather station in 
                         Paran{\'a}, it was possible to make a correspondence for each 
                         pixel. With data from the satellite and the surface weather 
                         stations, it was made several graphs in order to compare the 
                         linear correlation between these values. This procedure was made 
                         for three dates related to the occurance of frost: September 1, 
                         2002; July 11, 2003; September 3, 2003. All the correlations 
                         presented high values, indicating that the temperature obtained 
                         through the satellite is not significatively different from the 
                         data obtained by the weather stations. The turf temperature 
                         presented a larger correlation, as expected, considering that this 
                         is measured on the surface, while the minimum temperature of the 
                         air is measured 1.5 m above the surface.",
