Comparing model results from daily or monthly-average NSCAT winds

The model was spun up with 5 years of FSU climatological winds, then forced with ECMWF daily winds for Jan-Oct 1996. NSCAT winds were imposed from 1 Nov 1996 through 26 Jun 1997. Monthly-mean winds are a 31-day running mean over the daily NSCAT winds. At the beginning and end of the NSCAT period, the running mean was linearly tapered to the actual first and last values.

An interesting sidelight is that the high-pass filtered winds have very long zonal scales (fig2, difference field).
