Default Comparison between professional and amateur windspeed measurements.


The point I am trying to make is that
if one is to be taken seriously as an amateur meteorologist one should
at least attend to the obvious. The online software updating systems
and inexpensive weather stations have given the amateur a chance to
contribute.(within the limitations of their equipment) That chance
would seem to have been missed in many cases. Rainwater gauges
deliberately fixed under the eaves of one's bungalow and wind
measurement devices a couple of feet from the ground surrounded in
bushes are just a couple of examples which I have read about
online.These obvious flaws were openly admitted to by the website
owner! I am not criticising anybody here but if you choose to publish
your weather data online then do at least make an effort. Or all
amateur observers will always get tarred with the same brush. If you
nearest professional station is saying 24 m/s Westerly you really have
got to be kidding by publishing a 3 m/s Easterly reading online. :-)


Fair enough.

The position of my equipment can be seen at www.easterling.freeserve.co.uk/weather.html
(Any excuse for a plug!)

The anemometer is on a 10m pole (though not being in the middle of a
field may not satisfy Tudor!) The results do compare well with several
other places nearby (Camborne, Culdrose, Penzance Heliport etc.)
During 1992-1999 my rainfall was 99.5% of that recorded by EA at Drift
(2 miles away - same alt.

My pet hate is when people record data & then make some adustment.
Much better to report it as is & point out the limitations.
