[wxqc] Correct anemometer height

[spamfree]

For a home station, it probably doesn't matter much. A 10' difference in placement accounts for about a 0.011 in hg difference in pressure. However, you can easily adjust for this in your station calibration. The automated airport weather stations (ASOS) record a sensor pressure (the actual reading of the sensor) and a station pressure (the sensor pressure adjusted for the difference in elevation between the sensor location and the official station location such as the runway). This adjustment calculation takes into account temperature as well as elevation, but this is overkill for a home station, as a difference of 30 feet or less is very close to a constant value. My sensor for example, is in the second story of my home, above the official location of my station. But this difference is pretty much irrelevant since it is taken care of in the calibration of the barometer.

Can someone tell me what the proper height of the anemometer should be.  Currently mine is at the top of a 4"x4" wooded post about six feet off the ground.  I would like to increase that height to get more "official" readings.
