I look forward to more from NODC and from yourself once KNMI is updated.Dominicnoreply@blogger.comtag:blogger.com,1999:blog-2220966763638300672.post-5591448628275920652010-10-05T06:33:50.071-04:002010-10-05T06:33:50.071-04:00Watching that blink comparison, the Oct 4 graph lo...Watching that blink comparison, the Oct 4 graph looks like they smoothed the data. A lot of the jagged variation has been rounded off.Anonymousnoreply@blogger.com
