Abstract: A novel design of a Lyman-alpha hygrometer for surface layer flux measurements is presented using a variable pathlength. The benefit of this device is the capability for in situ calibration during a field experiment with only a short interruption of the measurements of 5 min or less. A description of the device, its operating specificationi, and an example of the calibration process are included. |
