Trend Removal:
ReferenceA weighted running mean is applied using low-pass filter weights from the IPCC-AR4. (The 30 weights can be found within the functions.ncl file under the remove_trend function.) These weights are roughly equivalent to a 30-yr low pass smoother. After the weighted running average is applied, the weighted array is subtracted from the raw array to effectively remove the long-term trend.

ModelThe ensemble mean global mean tas array is regressed upon the variable relavent for that particular metric, and then the regression map is scaled by the value of the ensemble mean global mean tas value at each timestep.This new array is then used to compute the metric.
