A web based system used to consult meteorological data to support the use of irrigation in Piauí State

Meteorological data consulting systems promote an appropriate use of water resources. The “Programming Hypertext Processor” (PHP) was chosen as a tool to develop an internet based system for dynamic administration of climatic information, such as rain, air temperature, relative humidity of the air, evapotranspiration and others. The main function of this system is the automatic generation of spread sheets using data recovered from database queries. This system boosted the way climatic data are manipulated. It also showed effectiveness when treating climatic variables, reaffirming its applicability to subsidize the use of irrigated cultures in Piaui state.
