Tim,
Using Weighted, Barnes, & Cressman analysis methods produces major errors in the following "wind" fields.
1. wind speed (barbs) kts
2. wind speed (vectors)
3. streamlines
And somewhat relatedly, neither the smoothing pass(SMTP) algorithm nor the smoothing coefficient(SMTC) appears to work with the above analysis routines, however, the Haltiner smoother(SMTH) does. And yes, I tried setting them using the script file rather than the menu.
hth,
Bob the Buggy
