Downscaling Maximum Temperatures to Subkilometer Resolutions in the Shenandoah National Park of Virginia, USA
Figure 4
Maps of mean for July 2012 resulting from the different steps in our downscaling method. Panel (a) shows 4 km PRISM output; panel (b) shows PRISM downscaled to 15 m in SNP using the 30-year PRISM lapse rates and without any corrections applied; panel (c) shows PRISM downscaled to 15 m in SNP with our corrections from Table 1 applied to each 15 m grid box; panel (d) shows estimated mean in SNP assuming a temperature increase of 3.3°C (average projected temperature increase from NARCCAP RCMs for SNP) applied to July, 2012 mean . Thin black lines denote elevation contours at 100 m spacing, with contour lines labeled; solid black line indicates the SNP boundary; black triangles mark temperature sensors; and the two ridgetop climate monitoring stations, Big Meadows and Pinnacles, are labeled. Note that the downscaling method is only applied to a 15 m DEM inside the SNP boundary (panels (b)–(d)).
