Atmospheric Water Vapor Measurements: Comparison of Microwave Radiometry and Lidar
The NASAJGSFC Crustal Dynamics Project microwave water vapor radiometer 003) is evaluated in terms of measurements of the integrated precipitable water vapor content of a particular column of the troposphere. The measurements were taken during the Atmospheric Moisture Intercomparison Study (ATMIS) held at Wallops Island, Virginia, during April 1989. Various water vapor sensing instruments were ...
متن کاملDiurnal variations in middle atmospheric water vapor by ground-based microwave radiometry
General comment: • Review of Scheiben et al., Diurnal variations in middle atmospheric water vapor by ground-based microwave radiometry This paper shows comparisons between observed diurnal variations of water vapor, and variations seen in WACCM. The paper is generally well written, and the WACCM analysis is good. I do have some major concerns with the presentation of the comparisons, and, part...
متن کاملThe accuracy of water vapor and cloud liquid determination by dual-frequency ground-based microwave radiometry
A dual frequency ground-based radiometer operating in the 1 to 1.4 cm wavelength range can provide continuous measurements of integrated water vapor and cloud liquid water. Using climatological data, the accuracy of the vapor and liquid determinations is estimated as a function of cloud amount. Limiting factors in the water determination are uncertainties in water vapor absorption coefficients ...
متن کاملResults of Year-Round Remotely Sensed Integrated Water Vapor by Ground-Based Microwave Radiometry
Based on two years of measurements with a time resolution of 1 min, some climatological findings on precipitable water vapor (PWV) and cloud liquid water (CLW) in central Europe are given. A weak diurnal cycle is apparent. The mean overall diurnal variation was about 0.15 cm in summer and 0.05 cm in winter, equivalent to 8% and 5%, respectively. The PWV increase starts in summer at about 0800 l...
