Hi all

This isn't a dig at anybody (at all) but I noticed the storm
presently buffeting Denmark produced some amazing results in published
measured windspeed.

These images were lifted from the Danish national weather service
website: DMI: Dansk Meteorological Institute.

The first image shows professional measurements while the second shows
amateur measurements.

Could it really be said that most of the amateur figures have any
scientific value whatsoever?

Or even any real value to the amateur weather watchers themselves?

It is certainly an area where the Danish amateur meteorologist could
and should seriously improve their performance.

Any constructive thoughts?

If you stick an anemometer on top of a 10m pole, it doesn't become
more accurate because the results are read by a professional.

It's really a matter of ignoring results from seriously non standard
equipment, and those where highly questionable adjustments have been
applied.

(Quality control on 'professional' sites is often far from perfect!)
