Optical depth
Measurement Categories: Aerosols, Cloud Properties
Description: A measure of how much light airborne particles, whether aerosols, cloud droplets, or ice particles, prevent from passing through a column of atmosphere. This type includes gaseous absorption and scattering, and is the most general case. See _aerosol op
