1981-2010 Climate Normals for Asheville, Charlotte, and Greenville-Spartanburg
NOAA's National Climatic Data Center (NCDC) released the 1981-2010 Normals on July 1, 2011. Climate Normals are the latest three-decade averages of climatological variables, including temperature and precipitation. This new product replaces the 1971-2000 Normals product. Unlike the 1971-2000 Normals, daily data were used extensively in the computation of daily temperature and precipitation normals, providing greater precision of intra-seasonal features. In previous installments, daily precipitation normals were computed as a spline fit through the monthly values. The drop-down menus below link to a set of graphs that compare the new 1981-2010 Normals to the previous 1971-2000 Normals for Asheville, Charlotte, and Greenville-Spartanburg. The following link will provide more information on the 1981-2010 Normals: http://www.ncdc.noaa.gov/oa/climate/normals/usnormals.html.
The new normals are available through our Climate Data Web page.
