These stations included the 93 stations (red points) used for the whole study period and were used to examine the spatial variation of trend magnitudes in temperature and temperature extremes during the period of 1961–2010 in the Great Basin.
jgrd50360-sup-0003-Figure_S3.tifTIFF image686KComparisons of seasonal average daily anomalies of four climate indices derived from 93 COOP stations (y-axis) with those derived from 127 COOP stations (x-axis) for the period of 1961–2010. The statistics suggest that no significant biases exist between these two compared datasets for each of the four climate indices.

The plotted anomaly in a given year was relative to the 30-years’ (1961–1990) seasonal mean. Winter—December, January, and February; spring—March, April, and May; summer—June, July, and August; autumn—September, October, and November.
