Scatter plots of county-level total biomass of four national products and CMS_RF against estimates from FIA_Jenkins. a NBCD_NCE at 30 m spatial resolution, b Blackard at 250 m spatial resolution, c Wilson at 250 m spatial resolution, d Saatchi at 250 m spatial resolution, and e CMS_RF at 30 m spatial resolution. The x axis represents the biomass totals from FIA_Jenkins, and the y axis represents corresponding national products in each plot. Red dashed line is the fitted regression line, and gray solid line is the 1:1 line. FIA_Jenkins represents biomass estimates using Jenkins allometrics and gap-filled for non-forest biomass.
