@IanWatkins various air quality instrumentation would be amazing! Did you consider dangling the sensors a metre or two below the Quadcopter? It might make the measurements easier + less noisy.
It's a bit different, but imagine being able to fly backwards and forwards over some polluter (a volcano, power station or factory?) and build up a volumetric map of the pollution levels.
