What is it? Temperature of the outside air.
Why is it important? Helps us understand the context of our other observations.
What does it mean? Tracking it throughout the year alongside the water temperature can be a fun way to compare other observations with seasonal changes.
Water Rangers Protocol: Make sure the thermometer is out of direct sunlight for at least 5 minutes. Do not hang the thermometer around your neck while measuring because your body temperature will affect the reading.
Pro Tip: Hang from tree! That way it’s out of direct sunlight and away from your hot body.
