Image Title:
Observed decadal mean annual precipitation change
Image Description:
Observed decadal mean annual precipitation change (deviations from the 1901-1960 average, %) for the Midwest U.S. (black line). 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). Gray lines indicate the 20th and 21st century simulations from 15 CMIP3 models, for the high (A2) emissions scenario. Observed precipitation variations are within the model simulations.
Attributes (variables name, description and units):
