From the start, the measurement of daily maximum and minimum air temperature within one hour of local solar noon has been a key GLOBE protocol. The low cost approach was to use a U-tube thermometer housed in a wooden instrument shelter facing away from the equator. The U-shaped tube contained mercury with pins on either side of the mercury. As the air temperature warmed the pin on one side would move while the other pin stayed in place; when the air cooled, the pin on the other side would be pushed up. The pins were held in place by magnetized strips behind the thermometer tube so that ...
