UPDATE: I'm making materials for all of my lectures available on my website (melstrong.org) either for people who are bored and stuck at home due to the virus, or for teachers looking of online content. For this lecture, I have some practical problems regarding mixing ratio and dew point with the answer keys.

First lesson on humidity. Covers mixing ratio and dew point, plus a bit of atmospheric composition. The next lecture after this is on relative humidity.

This was originally part of the Blue Planet Lecture Series at the University of New Mexico. If you are interested in weather, this lecture is now part of my playlist /"short course on weather/", where there are 15 other videos similar to this one.

Please take the opportunity to connect and share this video with your friends and family if you find it useful.
