One thing about the Cotton Region Shelter design is that it’s made of wood. Even though it is painted white, it still has a lot of thermal mass on the outside and it tends to unevenly heat the interior, especially on very hot and still days. I built a solar powered fan aspirator to hopefully even out the temperature spikes seen on the daily graphs during the hottest part of the day. Here is how I constructed it. Continue reading
After a recent rain event, I noticed that The Davis tipping bucket rain gauge was not reading correctly. For comparison purposes I have it mounted side by side with a standard 4″ manual gauge of known accuracy. The 4″ gauge registered 1.12″ of precipitation while the Davis gauge registered .88″ of rain.

This type of rain gauge is fairly accurate for most rainfall events. They do have a few flaws that can lead to errors in reporting. For this reason, I also use a manual 4″ rain gauge for backup. Here is a description of my setup and design for my station. Continue reading
