To obtain GDD accumulations for individual stations, visit our Cardinal and Station Scout tools. This tool requires users to submit a location, start and end dates, and a base temperature. Optional inputs include the ability to plot a comparison GDD time series (such as with different start and end dates or a different base temperature) and to plot comparison lines for historic years.
