RISGround-Based Determination of Low Altitude Temperature Profiles by Microwaves
Publisher: American Meteorological Society
Abstract: Vertical temperature profiles of the lower atmosphere are determined from clear air ground-based measurements of microwave thermal emission by oxygen. Angular emission data from two diverse meteorological locations are ...
Statistical Information Content of Radiation Measurements used in Indirect Sensing
Publisher: American Meteorological Society
Abstract: The information content of radiation measurements used in inferring profiles is defined as a reduction in uncertainty in the estimation of a profile after the measurements are introduced. The information is shown to depend ...
Ground-Based Microwave Radiometric Observations of Precipitable Water Vapor: A Comparison with Ground Truth from Two Radiosonde Observing Systems
Publisher: American Meteorological Society
Abstract: Dual-channel microwave radiometric measurements of precipitable water vapor are compared with values determined from two types of radiosondes. The first type is used in conventional soundings taken by the National Weather ...
Assimilation of Precipitable Water Measurements into a Mesoscale Numerical Model
Publisher: American Meteorological Society
Abstract: Significant progress has been made over the past decade in the development of remote-sensing instruments to profile wind and temperature. However, the current technology of profiling water vapor remotely is still far from ...
Statistical Retrieval of Humidity Profiles from Precipitable Water Vapor and Surface Measurements of Humidity and Temperature
Publisher: American Meteorological Society
Abstract: A new method is presented of statistical retrieval of humidity profiles based on measurements of surface temperature ?1, surface dewpoint ?2, and integrated water vapor ?3. In this method the retrieved values of humidity ...
Remote Sensing of Temperature Profiles from a Combination of Observations from the Satellite-Based Microwave Sounding Unit and the Ground-Based Profiler
Publisher: American Meteorological Society
Abstract: Temperature profiles are derived from ground- and satellite-based microwave radiometric observations. Data taken by the NOAA Profiler during December 1981 to December 1982, at Stapleton International Airport, Denver, ...
Quality Control of Ground-Based Radiometric Observations of Integrated Moisture Using Surface Meteorological Observations
Publisher: American Meteorological Society
Abstract: A method of quality control is presented for ground-based, dual-channel microwave measurements of integrated moisture. Such a method is necessary to eliminate spurious data arising from calibration uncertainties, electronic ...
Possible Near-IR Channels for Remote Sensing Precipitable Water Vapor from Geostationary Satellite Platforms
Publisher: American Meteorological Society
Abstract: Remote sensing of tropospheric water vapor profiles from current geostationary weather satellites is made using a few broadband infrared (IR) channels in the 6?13-µm region. Uncertainties greater than 20% exist in derived ...
Winter Icing and Storms Project (WISP)
Publisher: American Meteorological Society
Abstract: Field studies in support of the Winter Icing and Storms Project (WISP) were conducted in the Colorado Front Range area from 1 February to 31 March 1990(WISP90) and from 15 January to 5 April 1991 (WISP91). The main goals ...
Measurement of Low Amounts of Precipitable Water Vapor Using Ground-Based Millimeterwave Radiometry
Publisher: American Meteorological Society
Abstract: 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 ...
