Mark,
According to the "Site Specific Documentation" from the installation in early 1994 they installed a 26' (8 meter) tower. The same tower that was moved to the new location. The 30' on the blue print would represent the cross arm ("S"arm now with IFWS) and sensor.
I suppose the only real way to know is to measure it the next time someone is at the site.
Thanks, Shane

Yes, I believe it does. There are still documents out there that suggest a lower anemometer height but we consider the blue prints a very reliable source to confirm the 30 foot height.

Thank you to ever yone who helped on this request.

Ricky,
Can you answer Mark's question below about the Evansville ASOS?

I work for the Office of Air Quality and we use the meteorological data from several National Weather Serv ice sites throughout Indiana and surrounding states to conduct air dispersion modeling. We are trying to determine the actual anemometer height at the Evansville NWS ASOS station ( KEVV;72;432;EVANSVILLE REGIONAL;IN;United States;4;38

We have conflicting information that says the height is either 26 feet (7.92 meters) or 33 feet (10.0 meters). We know the anemometer height was 33 feet before 2008 but the site has mov ed so we are unsure if the anemometer height at the new site location (which we believe moved around the 2007 or 2008 time frame, based on slightly different latitude and longitude coordinates) lowered to 26 feet or remained at 33 feet. This change would be mean that we would need to re

- process our meteorological data at the lower anemometer height to establish representative wind profiles in order to predict modeled pollutant concentrations from companies in southwest Indiana.
If you could confirm the ane mometer height at the Evansville NWS ASOS station and supply a reliable website or inventory of updated anemometer heights, that would be very helpful.
Thank you for your attention to this issue.
