Crop (corn) heat units Crop heat units (CHU) are based on a similar principle to growing degree days. CHUs are calculated on a daily basis, using the maximum and minimum temperatures; however, the equation that is used is quite different. The CHU model uses separate calculations for maximum and minimum temperatures. CHU values are only accumulated during the Growing Season which spans from April 1 through October 31. 2017-05-08 2019-08-02 Agriculture and Agri-Food Canada agri-geomatics-agrog@agr.gc.ca Nature and EnvironmentScience and TechnologyagclimateCHFarmlandsCropsAgricultureTemperaturePrecipitation Data Product Specification (English)PDF http://www.agr.gc.ca/atlas/supportdocument_documentdesupport/aafcAgClimate/en/ISO_19131_AgClimate_-_Data_Product_Specification.pdf Data Product Specification (French)PDF http://www.agr.gc.ca/atlas/supportdocument_documentdesupport/aafcAgClimate/fr/Donnees_agroclimat_-_SPC.pdf Agroclimate Interactive Maps (English)HTML http://www.agr.gc.ca/atlas/agclimate Agroclimate Interactive Maps (French)HTML http://www.agr.gc.ca/atlas/agclimat Crop (corn) heat unitsESRI REST https://www5.agr.gc.ca/atlas/rest/services/app_agclimate_agclimat/agclimate_ch/ImageServer Crop (corn) heat unitsWMS https://www5.agr.gc.ca/atlas/services/app_agclimate_agclimat/agclimate_ch/ImageServer/WMSServer?request=GetCapabilities&service=WMS&layers=0&legend_format=image/png Pre-packaged GeoTIF files (No linguistic component)GeoTIF http://www.agr.gc.ca/atlas/data_donnees/cli/agClimate/tif/ch/ Using AAFC Climate ServicesPDF http://www.agr.gc.ca/atlas/supportdocument_documentdesupport/aafcAgClimate/en/Using_AAFC_Climate_Services.pdf Crop (corn) heat unitsESRI REST https://www5.agr.gc.ca/atlas/rest/services/app_agclimate_agclimat/agclimate_ch/ImageServer Crop (corn) heat unitsWMS https://www5.agr.gc.ca/atlas/services/app_agclimate_agclimat/agclimate_ch/ImageServer/WMSServer?request=GetCapabilities&service=WMS&layers=0&legend_format=image/png

Crop (corn) heat units

Crop heat units (CHU) are based on a similar principle to growing degree days. CHUs are calculated on a daily basis, using the maximum and minimum temperatures; however, the equation that is used is quite different. The CHU model uses separate calculations for maximum and minimum temperatures.

CHU values are only accumulated during the Growing Season which spans from April 1 through October 31.
