In the WRF guide, it states "dfi_cutoff_seconds = 3600 (should not be longer than the filter window)"
In the TDFI, WRF integrates backward from 0 to -2T, and then integrates forward from -T to T. Then what is the filter window, T or 2T?
In the Peckham et. al. (2016) paper, they set T=20min, and the cutoff frequency to be 1h. Do these numbers make sense given "should not be longer than the filter window"?
