ABSTRACT
This chapter presents the brief explanation of climate model outputs, including regional climate models (RCM) output. Statistical downscaling employs statistical relationships between observed local variables and climate variables, acquisition of appropriate datasets is important. The study of the Intergovermental Panel on Climate Change Fifth Assessment Report through Coupled Model Intercomparison Project, employs a number of global climate models (GCM) and Earth system Models of Intermediate Complexity. The format of downloaded data is mostly "nc". Climate reanalysis numerically describes the past climate by combining models with observations. The analysis estimates atmospheric parameters and surface parameters. Then, GCM outputs are used to predict future conditions of the local variable by replacing the reanalysis data with GCM outputs. While GCMs are widely used in the assessment of climate change impact, their horizontal resolutions are too coarse to assess the climate change impact in a local scale. A number of GCM and RCM outputs are available on websites.
