Automated Weather Station n n An automatic weather station (AWS) is an automated version of the traditional weather station, either to save human labor or to enable measurements from remote areas. The system may report in near real time or save the data for later recovery. In OK- Mesonet
Precision Forecasting Systems n Input data includes: q q q National Weather Service (NWS) Global Forecast System (GFS) ETA models The NWS MAV and MEX MOS European Forecast Center's ECMWF Climatology and observational data.
Climatological Archives n Small farmers have watched the weather for years n Built a knowledge base of historical climate data
Simulated Production Models n Studying crop response to changes in: q q q n Genotype Cultivar Soil Weather Climatic patterns Management practices Vulnerability of crops to weather events
Temperature n Growing Degree Days (GDD) q q Crop Growth Insects Stress Soil Temperature
