                         complete survey rockets or launcher vehicles launching mission, 
                         several operations are accomplished, in whose execution the risks 
                         of atmospheric discharges occurrence should be reduced to the 
                         minimum possible. An electric field and lightning detection 
                         monitoring system was installed in the Launching Center of 
                         Alc{\^a}ntara (CLA), at Maranh{\~a}o, allowing the electrical 
                         activity accompaniment of atmospherical origin. The data analysis 
                         obtained from the system allowed defining criteria related in the 
                         CLA electrical activity of atmospherical origin and, more 
                         specifically, at the launch pad, to support accomplishment 
                         decisions, or not, the operations involved in a launching mission 
                         as, for example, during the vehicle assembly phase, launching 
                         simulation and in the launching itself. Besides the data generated 
                         by the atmospherical electrical activity monitoring system 
                         installed at CLA, it was used, also, the existent Alc{\^a}ntara 
                         area climatological data available in the Aeronautic and Space 
                         Institute (IAE) on its Atmospheric Sciences Division (ACA) at the 
                         Aerospace Technical Center (CTA). This climatological data were 
                         collected by the land meteorological station at the CLA, located 
                         in the latitude 02° 22'S, longitude 44° 23'W, constituted by a 11 
                         (eleven) years (1993 - 2003) temporal series and by the S{\~a}o 
                         Lu{\'{\i}}sīs airport meteorological station, constituted by a
