MulGETS is a new Matlab-based stochastic weather generator for generating multi-site precipitation and temperature. It is an extension of a single-site weather generator WeaGETS (http://www.mathworks.com/matlabcentral/fileexchange/29136-stochastic-weather-generator-weagets) that makes it possible to drive individual single-site models with temporally independent but spatially correlated random numbers. Similar to an un-modified single-site weather generator, precipitation occurrence is generated using a first-order two-state Markov chain, and temperature is generated using the first-order autoregressive model. However, instead of generating daily precipitation amounts based on a single gamma distribution, MulGETS uses a multi-gamma distribution to address the spatial correlation of precipitation amounts. By modifying its parameters based on climate model outputs, MulGETS can easily be used as a downscaling tool for climate change impact studies.
