Quickly changing weather conditions and increased variations in weather conditions both within a growing season and from one year to the next make having quick and easy access to the most recent weather data and tools that can assist in applying these weather data to on-farm decisions more important. Cornell’s Climate Smart Farming Program (CSF) Decision Tools (climatesmartfarming.org/) were developed through a partnership between the CSF program and the Northeast Regional Climate Center (NRCC). The NRCC archives and supplies daily temperature observations from the National Weather Service (NWS) and daily precipitation from NWS radar data. These data are interpolated to a 4-km-by-4-km grid allowing farmers in the region to access accurate information for their farm even without a weather station on their site.
