To get a sense of how much these sources agree with each other, you can view a comparison of Des Moines and the stations that contribute to our estimates of its temperature history and climate. KDSM, 56% 5 mi, 85 ft KIKV, 40% 7 mi, 39 ft KPRO, 4% 33 mi, 141 ft © OpenStreetMap contributors Perry Municipal Airport (KPRO, 3.7%, 33 mi, northwest, 141 ft elevation change).Ankeny Regional Airport (KIKV, 40%, 7 mi, north, 39 ft elevation change).Des Moines International Airport (KDSM, 56%, 5 mi, southwest, 85 ft elevation change).The stations contributing to this reconstruction are: The estimated value at Des Moines is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Des Moines and a given station. There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Des Moines.įor each station, the records are corrected for the elevation difference between that station and Des Moines according to the International Standard Atmosphere, and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. This report illustrates the typical weather in Des Moines, based on a statistical analysis of historical hourly weather reports and model reconstructions from Januto December 31, 2016.
