On a calm, clear night, the ground cools very efficiently by radiating heat back into the atmosphere. This lowers the ...

My high school had a weather station on the roof so earth-science students could make measurements each morning. We climbed up a ladder in the janitor's closet, went through a hatch and out onto the ...

Find out about humidity and how to measure humidity with help from BBC Weather's Kawser Quamer in this BBC Bitesize Scotland article for First and Second Level CfE.

This resource is suitable for weather topics for primary school learners. Have you ever felt hot and sweaty even when you haven't done any exercise? That might be because of humidity. But what is ...

The relative humidity level will make it look like it is VERY humid outside if you were to use relative humidity as your measurement of moisture.

The dew point is the temperature that we would have to cool the air down to for condensation (or dew) to begin forming.

There are three ways to measure relative humidity. Current automated weather systems measure the reflection of a beam of light on a mirror. The mirror is chilled until atmospheric moisture condenses ...

A new saturation hygrometer capable of measuring relative humidity between 95 and 105% is described. The hygrometer uses a thermally thin mirror on which condensation is controlled by limiting the ...

Relative humidity has been used to describe moisture levels in the atmosphere for so long that it has become the most common (though often misunderstood) moisture measurement. And there is truth to ...

This article from Omega Engineering discusses the challenges involved with relative humidity in the lab. 5 reasons to wirelessly measure relative humidity are discussed.
