Climate data from approximately 99 climate stations, 61 snow monitoring stations, and 36 Remote Automated Weather Stations (RAWS) within and near the three units of the Central Alaska Network, (Wrangell-St. Elias National Park and Preserve, Denali National Park and Preserve, and Yukon-Charley Rivers National Preserve), have been documented, tabulated, summarized, and analyzed to provide a record of past climate changes and fluctuations over the period of record (beginning in 1899), to provide baseline normals and averages to help assess future climate variations, and to gain some insight into the possible causes of the climate variations.
