#80,

David, one of my email addresses bassguitarmaestro AT hotmail DOT com. You can send me an email at that address. I don’t use that email address for much as it’s not my primary so I don’t mind giving it out. I’m not available this weekend but next weekend is probably pretty open. Send me an email and let me know.

With respect to local GHG effects:

#78: Sure. I’m not sure how to send you my e-mail address without posting it.

Thanks, I will download it tomorrow and see what I can find.

#74 David,

Let me know if you’re interested in tracking a couple of these down. I’m pretty sure there is a COOP station in Denton somewhere, but I would have to double-check. Gainesville isn’t too far away either, but will have to wait a bit for the floodwaters to recede I’m sure. I thought we got alot of rain the other day but they received well over 12 inches in a very short period of time.

Re: #64

Jonathan, a handheld GPS is not necessary. Instead, download a free GIS software program called Global Mapper. http://www.globalmapper.com

Then, get the official coordinates for the station you would like to survey from the Multi-network Metadata System and plug them into Global Mapper and download the aerial photo from Terraserver. After surveying the site, get the actual Lat/Lon coordinates through Global Mapper. This method is every bit as accurate as a handheld GPS would be.

You could also do this through Google Earth although someone a while back reported that the coordinates were off a bit. I’ve never experienced this problem using Global Mapper.

RE: #75 – There is a treatment plant located on the border of Redwood City and Menlo Park, CA, on one of the major sloughs off of the Bay. They actually burn the methane for cogeneration using turbojet powered generators. You can feel the heat from it at tens of feet away, and the exhausts look just like turboprop exhausts – you can see the mirage effect from all the heat.

As mentioned, sewage plants use air injection (often blowers but sometimes churners) to help the “bugs” metabolize the organics. The nitrogen in this injected air stream exits the top of the system in a warm and humid plume, which also often contains aerosol-like fine droplets which collect on surfaces. Sometimes the plume (and associated odor) rise but at other times it drifts around near ground level (creating the familiar unpleasant odor of sewage treatment plants).

Generally, as the organic load on a sewage plant increases, the air injection increases, which increases the aeration plume, which increases the anthropogenic effect (likely a warming).

So, you have anthropogenic warmth, humidity and fine droplets, as well as large bodies of water and concrete. What a horrible place to use for climatological studies.

Anthony, I think you’re on to something.

#64: I live in the DFW area. I did not see the Denton one in the list, but I know that there’s one in Greenville.
