Most problems with these types of temperature measurements come from poor placement in the environment they are measuring giving incorrect and often unrecognized errors.
Air circulation and radiation are the most frequent source of these errors. So white is the color of choice whether it's painted or preferably the color of the material. Small white plastic plates with spacers between them can create a nice finned radiation shield, plastic flower pots work well also. ************************************************** Peter Kirchner, Graduate Research Scientist Sierra Nevada Research Institute University of California, Merced -----Original Message----- From: Ecological Society of America: grants, jobs, news [mailto:[EMAIL PROTECTED] On Behalf Of Steve Hanser Sent: Wednesday, August 20, 2008 9:47 AM To: [email protected] Subject: [ECOLOG-L] inexpensive iButton radiation shield I am looking for an inexpensive method for constructing radiation shielding for iButton thermochrons. I am using iButtons to take winter temperatures in snowy conditions and I need protection from both direct and indirect solar radiation. I would appreciate any ideas. Thanks.
