WebThe primary comparison will be between (i) the (Sun et al. 2007), whereas statistical downscaling methods GCM and RCM simulations of precipitation interpo- have also claimed success, such as hidden Markov lated linearly to the station locations and (ii) MOS models (HMMs) that generate stochastic daily sequences corrections of station values ... WebDownscaling The goal of downscaling is to create locally accurate climate information from global-scale data by placing it in the context of observed local climatological conditions. This improves the spatial and temporal resolution of the data, making it more useful for local and regional analyses. Downscaling results. WebApr 22, 2013 · Statistical downscaling of precipitation is required as part of many climate change studies. Statistical downscaling based on regression models requires one to sample from the conditional distribution to preserve the variance of observed precipitation. In this paper, we present a new technique for downscaling precipitation. ... simply peel refill bottle
