Net Solar Heating Resource Maps for US Climates: 2020 and 2000

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).
