EVALUATION OF CLIMATE SCENARIOS PROJECTIONS AND ASSOCIATED ERRORS IN A REGION IN ILLINOIS (USA) ACCORDING TO CMIP5 MODELS
Observed data from different parts of the world shows that many natural systems are being affected by regional climate changes. Some models has been used as a tool to help studies to evaluate the impacts of climate changes in different sectors.However, this models has some errors due to the parametr...
