Hi, <br><br>
A possible source is

<br><br>
It looks like private and public weather station located around the world
and some has wind data.<br><br>

I was ventilating the idea of non for profit local data centres,
collecting an providing data for facility management but also for
planning building integrated solar and wind harvesting.<br>
Having all those web-enabled devices this should not be very costly.<br>
<br>
Any progress anyhwere that this idea will materialise? While public
administrations sleeping, finally the google boys may take over and we
will risk a 100% dependency on them. I just learned that even sketchup is
now part of building modeling.<br>

<br><br>
Hello,<br><br>
<br><br>
Unfortunately, historical wind speeds on TMY files that come from NOAA
data are from peak 5 minute gusts, which can have little correlation to
average hourly wind speeds. At some stations integrating sensors have
been added, but it will take time to push these data through the average
year data base.<br><br>
<br><br>
In addition, previous work in England using ultrasonic sensors has shown
that NOAA data also suffers from severe drop out at speeds less than 5 to
10 MPH, which means that most sites show "0" wind speed,
whereas there is actually some wind, but not enough to move the cups on
the anemometer. This can be a problem for simulation of natural
ventilation.<br><br>
<br><br>
ASHRAE's TC 4.2 continues to discussed these and other issues, which can
be viewed on ASHRAE web page in their meeting minutes.<br><br>

Dear Leen<br><br>
Most weather data quotes the reference wind speed which is that at 10m
above the ground as measured at certain weather stations. Adjustment
factors are then made for levels of surface roughness, I.e. urban, rural
environments. I think the TMY follows the same convention.<br><br>

Hi,<br><br>
can anyone tell me what wind speed is exactly meant in the TMY. Is it
the<br>
free, undisturbed wind speed, the wind speed above the roof, the wind
speed<br>
at 10 metres above the ground ....<br><br>
Thanks,<br><br>
Leen<br><br>
