                         over the summer season (October to March in Brazi). This paper 
                         aims at evaluating clear sky conditions over four Brazilian states 
                         (S{\~a}o Paulo, Paran{\'a}, Santa Catarina, and Rio Grande do 
                         Sul) to assess suitable observation conditions for a monthly basis 
                         operational crop monitoring system. Cloudiness was analyzed using 
                         MODIS Cloud Mask product (MOD35), which presents four labels for 
                         cloud cover status: cloudy, uncertainty, probably clear and 
                         confident clear. R software was used to compute average values of 
                         clear sky with a confidence interval of 95% for each month between 
                         July 1st, 2000 and June 30th, 2013. Results showed significant 
                         differences within and between the four tested states. Moreover, 
                         the period from November to March presented 50% less clear sky 
                         areas when compared to April to October.",
