10m Wind Altitude

<< < (2/2)

TheBushPilot:
IIRC WMO actually changed the height of wind measurement way back when to accommodate for the larger size of modern aircraft.

I know wind at 2 meters is not standard for general application meteorological stations but quite a few of the state and university funded mesonet projects utilize that measurement. I know Kansas and Oklahoma do so for agriculture, and Missouri while 3 meters is closer to 2 than 10. There are also probably some applications of 2 m with the EPA if I had to guess, similar to 9/2m temp delta calculations. While it may not be useful to the average person assuming they are in an obstructed place, we could argue the same for 10 m wind. It's simply a point measurement we can (I guess) interpolate what it may be where we are.

Live, high resolution temp and wind data of the whole lower atmosphere! If only there was an unlimited budget! But I digress....

This reminds me of some pictures of a project (that I cannot remember the name of  ](*,)) I found a long time ago.

Getting PBL data is actually possible with SODAR/LiDAR. I believe the West Texas Mesonet and the NYS Mesonet utilize this technology operationally. Albeit only at select locations as that technology is $$$. I know the NSSL also does this with CLAMPS which is basically a mobile trailer weather station with remote sensing capabilities and with their mobile LiDAR trucks.

Very interesting thoughts nonetheless.

Cheers

It would be interesting to know the results of that study, and see how the wind data at various heights, measured at the same time, varies.

Given that a median-ish height for air-carrier aircraft control surfaces is about 10 meters AGL, that's why it's measured there.

Does make sense. I'm certainly not in favor of doing away with 10m wind measurements. I just wonder if there's some value of adding a 2m wind in addition.

The National Wind Technology Center of NREL has 3 135 meter towers that provide tons of observations from 2, 5, 10, 20, 50 and 80 meters, and they provide one minute resolution data.
