Laser Hygrometer (Port City Instruments)

Partner: Stockholm University

The laser hygrometer provides accurate measurements of water vapor concentrations in the sampled air using the absorption of water vapor at specific wavelengths. Having accurate information about the humidity and water vapor in the conditions that we find particles in is important to understand processes affecting them and how they affect clouds, as well as judging the conditions inside of our instruments where we take our measurements.
