Global Climate Models and Climate Data: a User Guide for Economists

چکیده
This paper provides an introduction to climate data sets, climate models, and the output they provide. We identify five major issues related to the use of gridded historical weather products and climate model output: Spatially specific prediction error due to the coarse resolution of climate model output; spatially varying correlations between different weather indicators; differences in cross sectional versus time series variation, strong spatial correlation in weather variables; and finally the endogeneity of weather coverage. We discuss the conceptual issues arising from these five issues for economic impact studies of climate change.

متن کاملPrediction of Climate Change in Western of Iran using Downscaling of HadCM3 Model under Different Scenarios
Abstract Considering that water resources are at risk from climate change, the study of temperature and precipitation changes in the coming years can lead to droughts such as droughts, sudden floods, high evaporation and environmental degradation. To this end, global climate models (GCMs) are designed to assess climate change. The outputs of these models have low spatial accuracy. In order ...

Two major issues through studies on hydrological impact assessment of climate change are the sufficiency of historical data and selection of the best rainfall-runoff model. Climate models, with the ability to simulate climatic variables, are considered as references for future projections. Therefore, the rainfall-runoff model must be able to simulate streamflow using only these variables. Curre...
