The mandate area of the International Center for Agricultural Research in the Dry Areas (ICARDA) extends from northwest Africa to central Asia, includes 26 countries, and is home to more than 755 million people. The growing regions of those countries are marked by climate diversity, but very little climate information is available to ICARDA plant breeders. To meet that need a newly developed Windows-based PC application provides agricultural scientists with high resolution climate information. The database from which the application derives climate information required the generation of weather generator parameters from the station data of ~ 650 meteorological stations. From those parameters the software calculates climate statistics at user-selected latitude-longitude coordinates, calculated over arbitrarily defined periods within summer or winter growing seasons. The statistics reported include crop evapotranspiration estimates derived from the FAO-56 single crop coefficient algorithm, probabilities of exceedance of both cumulative rainfall and growing degree days, the probability that minimum and maximum daily temperatures will exceed user-defined temperature thresholds, and the probability of heat stress, cold stress and dry periods of varying duration.
