These files contain U.S. national map packages (ESRI ArcMap 10.5) for 2000 and 2020, including: Heating season length and intensity (monthly heating degree-days evaluated from a base temperature of 18.3 ºC); Residential heating energy needs (monthly kWh per household); Solar heating resources on 10m2 surfaces of optimal tilt (monthly Wh); Optimal south-facing tilt values for solar heat collection (angular degrees above horizontal); Net solar heating resources on 10m2 optimally-tilted collector surfaces (NSHR10) (monthly MWh per household and sums over 10km x 10km sectors); Proportions of the NSHR10 provided by diffuse radiation (monthly percentage by location); Collector areas needed to intercept solar radiation equal to household heating needs (monthly m2); Median absolute deviations in the NSHR10 obtained with twelve consecutive years of solar radiation data (annual MWh and percentage). Please see associated publication (Rempel et al. 2020) for source data and methodological details.
