Evaluation of the MOZAIC Capacitive Hygrometer during the airborne field study CIRRUS-III
The MOZAIC Capacitive Hygrometer (MCH) is usually operated aboard passenger aircraft in the framework of MOZAIC (Measurement of Ozone by Airbus In-Service Aircraft) for measuring atmospheric relative humidity (RH). In order to evaluate the performance of the MCH, the instrument was operated aboard a Learjet 35A research aircraft as part of the CIRRUS-III field study together with a closed-cell ...
متن کاملField Evaluation of Polymer Capacitive Humidity Sensors for Bowen Ratio Energy Balance Flux Measurements
The possibility of reliable, reasonably accurate and relatively inexpensive estimates of sensible heat and latent energy fluxes was investigated using a commercial combination thin-film polymer capacitive relative humidity and adjacent temperature sensor instrument. Long-term and unattended water vapour pressure profile difference measurements using low-power combination instruments were compar...
متن کاملCapacitive Humidity Sensor–Design and Its Application in Measurement Science
A hygrometer is an apparatus that measure humidity. Modern electronic devices use temperature of condensation or change in electrical capacitance to measure humidity difference. Humidity sensors are employed to provide an indication of moisture levels in the environment. To measure moisture level, various technologies are used. A capacitive type moisture sensor consisting of nanoporous thin fil...
متن کاملAbsolute and differential measurement of water vapor supersaturation using a commercial thin-film sensor
We describe a technique for measuring the water vapor supersaturation of normal air over a temperature range of 240&T&0 °C. The measurements use an inexpensive commercial hygrometer which is based on a thin-film capacitive sensor. The time required for the sensor to reach equilibrium was found to increase exponentially with decreasing sensor temperature, exceeding 2 min for T5230 °C; however, t...
متن کاملTen Years of Measurements of Tropical Upper-Tropospheric Water Vapor by MOZAIC. Part II: Assessing the ECMWF Humidity Analysis
In a recent publication (Part I), the authors introduced a data source—Measurement of Ozone and Water Vapor by Airbus In-Service Aircraft (MOZAIC)—for monitoring and studying upper-tropospheric water vapor (UTWV) and analyzed 10 yr (1994–2004) of MOZAIC measurements of tropical UTWV in its climatology, variability, transport, and relation to deep convection. In this study (Part II), MOZAIC is u...
