General Information

1895-2011 trends in temperature anomaly (F/decade) and precipitation anomaly (inches/decade) based on a new gridded version of COOP data from the National Climatic Data Center, the CDDv2 data set (R. Vose, personal communication, July 27, 2012) for the Southwest U.S., for each season as well as the year as a whole. Only values statistically significant at the 95% confidence level are displayed. Statistical significance of trends was assessed using Kendalls tau coefficient. The test using tau is a non-parametric hypothesis test.
