A good source might be the datasets put together as part of the VEMAP project, which provide a gridded coverage for the whole US. Since the project began in the mid-1990s, however, I suspect that there may be some changes to the most recent climate models. Mark D. Quoting "Kaduk, Dr J." <[EMA

Microphone Construction?

Dear Ecologgers, I am beginning my master's research and I need to construct a microphone that maximizes the range of frequencies it can record. I will be using my microphone to record vocalizations and other vibrations created by a captive animal that may be using ultrasonic and infras

Dear friends, I am preparing an article about the effects of cattle grazing on the structure of subtropical riparian forests, and I want to depart from the ecological foundations of the issue: what kind of predators are cows and what kind of effects one could expect them to have on fo

At UCLA, I had far too many professors who, although they may have been good scientists, shouldn't have been allowed within 20 feet of a classroom. Some were burned out; others simply didn't care about teaching or didn't know how to do it. I don't know how you can say the professor who was turn

Dear Carl, did you try the IPCC data centre? http://ipcc-ddc.cru.uea.ac.uk/ You should be able to get mean monthly global fields for th 2080's for a couple of models and scenarios. I should like to stress though that these data will NOT be "for the vicinity of Urbana, Illinois" but rather for
