<h3>R-Factor Raster</h3>

<p>The rainfall-runoff erosivity factor (R-factor) quantifies the effects of raindrop impacts and reflects the amount and rate of runoff associated with the rain. R-factor raster data for the coterminous United States and six of the main Hawaiian Islands are available from the NOAA Office for Coastal Management. For areas not covered by these data, a method to calculate R-factor is described in chapter 2 of the USDA Handbook Number 703 (Wischmeier and Smith, 1978)<a href="https://www.ars.usda.gov/ARSUserFiles/64080530/RUSLE/AH_703.pdf">PDF, 21.4 MB</a>.</p>
