Okay, you are going to need a thermometer and a sling psychrometer. Any discussion of the air temperature should include the relative humidity. Measurements describes the tools used to determine accurate temperatures and other weather data.
1. Here are the Air Temperature and the Relative Humidity eTraining module slides. Instead, you may want to read this Discussion on Humidity.
2. You’ll need instructions to Calibrate and Take Air Temeperatures. Yes, GLOBE is very specific.
3. Air Temperature Protocols and Relative Humidity Protocols both have field guides, activities, and specific protocols, such as Surface Temperature Protocol.
4. Here is Flinn’s Sling Psychrometer Worksheet. Here is the GLOBE protocol and abbreviated protocol.
5. Here, here, and here are plans to build a sling psychrometer. Here are instructions to make a bottle thermometer. I like to let kids build their own models and then compare theirs to thermometers and sling psychrometers we bought.
