This device can detect water vapor, sea spray, pollen, smoke from forest fires, and volcanic ash in the atmosphere as well as monitor industrial pollution. More, it can make your favorite young scientist feel personally connected to the earth as a living interconnected system.
A week after a raging dust storm scours the Sahara, your young scientist may be able to detect the debris floating high up over your house. When a volcano goes off anywhere in the world, s/he will be able to observe it in the air above!
