MACAv2-METDATA: University of Idaho, Multivariate Adaptive Constructed Analogs Applied to Global Climate Models (IDAHO_EPSCOR/MACAv2_METDATA)
Version 2
The MACAv2-METDATA dataset is a collection of 20 global
climate models covering the coterminous USA. The Multivariate Adaptive
Constructed Analogs (MACA) method is a statistical downscaling
method which utilizes a training dataset (i.e. a meteorological
observation dataset) to remove historical biases and match spatial
patterns in climate model output.
The MACA method was used to downscale the model output from 20
global climate models (GCMs) of the Coupled Model Inter-Comparison
Project 5 (CMIP5) for the historical GCM forcings (1950-2005) and
the future Representative Concentration Pathways (RCPs) RCP 4.5
and RCP 8.5 scenarios (2006-2100) from the native resolution of
the GCMS to 4km.
