Woodward Academy's weather data is collected by a Davis Vantage Pro instrument package mounted on the roof of the Carlos Science Center at Woodward Academy in College Park, Georgia. The wind instruments are located about 6 feet (2 meters) above the peak of the roof, a bit more than 50 feet (15 meters) above the ground. Due to local obstructions, wind speeds are slightly less than measured at KATL (Harstsfield-Jackson International Airport) a few miles to the south. The temperature and humidity probes are in a solar radiation shield (not fan aspirated), just off the north side of the building, usually in shade, about 35 feet (11 meters) above the ground. Temperatures are very similar to those at KATL, with highs almost identical and lows averaging about half a degree warmer than KATL's. Data are uploaded every 30 minutes.

The forecasts are produced by WXSIM, a program written by Tom Ehrensperger, who has been teaching physics, astronomy, and meteorology at Woodward for over 20 years. WXSIM is running in automated mode on a computer in the Science Center. The forecasts are intended to be specific for KATL, but also incorporate recent data from Woodward's instruments and should closely match conditions at the school. Forecasts are based on data from about 5 AM, 7 AM, 1 PM, 4 PM, 7 PM, and 10 PM and are uploaded about 27 minutes after these hours.
