Signatures of the 2-day wave and sudden stratospheric warmings in Arctic water vapour observed by ground-based microwave radiometry
The ground-based microwave radiometer MIAWARA-C recorded the upper stratospheric and lower mesospheric water vapour distribution continuously from June 2011 to March 2013 above the Arctic station of Sodankylä, Finland (67.4 N, 26.6 E) without major interruptions and offers water vapour profiles with temporal resolution of 1 h for average conditions. The water vapour time series of MIAWARA-C sho...
متن کاملMeasurements of Precipitable Water Vapor by GPS, Radiosondes, and a Microwave Water Vapor Radiometer
Results from the Westford WAter Vapor Experiment (WWAVE) will be discussed. This experiment was designed to measure the temporal and spatial variability of the total precipitable water vapor (PWV) over an area of roughly 25 km radius around the Haystack Observatory in Westford, MA. The main experiment was conducted from August 15 to August 30, 1995, and a variety of techniques were used to meas...
متن کاملMeasurement of Low Amounts of Precipitable Water Vapor Using Ground-Based Millimeterwave Radiometry
Extremely dry conditions characterized by amounts of precipitable water vapor (PWV) as low as 1–2 mm commonly occur in high-latitude regions during the winter months. While such dry atmospheres carry only a few percent of the latent heat energy compared to tropical atmospheres, the effects of low vapor amounts on the polar radiation budget—both directly through modulation of longwave radiation ...
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 ...
