Abstract

A new fast-response humidity sensor has been designed, manufactured and evaluated. The new sensor is based on the NSTAP, which is a miniature hot-wire used to measure small scale velocity fluctuations. It is manufactured in-house using semiconductor manufacturing techniques, with resulting high flexibility in the process for optimization to different measurement conditions. It is shown that the sensor has high sensitivity to humidity, yet low sensitivity to velocity. In combination with conventional hot-wires these new sensors will allow for detailed investigation of the scaling of the latent heat flux in the atmospheric boundary layer.
