Coastal Aerosol Profiling with a Camera Lidar and Nephelometer
(American Meteorological Society, 2010)A bistatic lidar configuration of a wide-angle camera (100°) and vertically pointed laser (532 nm) was used to profile aerosols at a coastal site. Aerosol profiles were measured on two evenings from the surface through the ... -
Wavelet Analysis of Atmospheric Turbulence over a Coral Reef Flat
(American Meteorological Society, 2011)he world?s tropical coral reefs are at risk of severe bleaching episodes and species decline in response to global climate variability. The ecological and economic value of reef ecosystems is enormous, yet very little is ... -
Assessment of a New Anemometry System for the Met Office’s Moored Buoy Network
(American Meteorological Society, 2010)Since the late 1980s the Met Office has operated a network of Marine Automatic Weather Stations (MAWS) around the United Kingdom. The network includes a number of instrumented moored buoys, which are mainly in exposed ... -
A Study of a Retrieval Method for Temperature and Humidity Profiles from Microwave Radiometer Observations Based on Principal Component Analysis and Stepwise Regression
(American Meteorological Society, 2010)This paper discusses the application of principal component analysis and stepwise regression in the retrieval of vertical profiles of temperature and humidity based on the measurements of a 35-channel microwave radiometer. ... -
Optimal Determination of Parameters for Gamma-Type Drop Size Distributions Based on Moments
(American Meteorological Society, 2011)easured raindrop size distributions are often approximated by analytical functions. The parameters determining such functions are usually derived from measured data. This procedure can suffer from various uncertainties. ... -
An Undular Bore and Gravity Waves Illustrated by Dramatic Time-Lapse Photography
(American Meteorological Society, 2010)On 6 May 2007, an intense atmospheric undular bore moved over eastern Iowa. A ?Webcam? in Tama, Iowa, captured dramatic images of the effects of the bore and associated gravity waves on cloud features, because its viewing ... -
Polarimetric Phased-Array Radar for Weather Measurement: A Planar or Cylindrical Configuration?
(American Meteorological Society, 2010)This paper suggests a cylindrical configuration for agile beam polarimetric phased-array radar (PPAR) for weather surveillance. The most often used array configuration for PAR is a planar array antenna. The planar ... -
Observational Studies of Atmospheric Aerosols over Bozeman, Montana, Using a Two-Color Lidar, a Water Vapor DIAL, a Solar Radiometer, and a Ground-Based Nephelometer over a 24-h Period
(American Meteorological Society, 2010)Coordinated observational data of atmospheric aerosols were collected over a 24-h period between 2300 mountain daylight time (MDT) on 27 August 2009 and 2300 MDT on 28 August 2009 at Bozeman, Montana (45.66°N, 111.04°W, ... -
Quality Control and Calibration of the Dual-Polarization Radar at Kwajalein, RMI
(American Meteorological Society, 2010)The dual-polarization weather radar on the Kwajalein Atoll in the Republic of the Marshall Islands (KPOL) is one of the only full-time (24/7) operational S-band dual-polarimetric (DP) radars in the tropics. Through the use ... -
An Observationally Generated A Priori Database for Microwave Rainfall Retrievals
(American Meteorological Society, 2010)The combination of active and passive microwave sensors on board the Tropical Rainfall Measuring Mission (TRMM) satellite have been used to construct observationally constrained databases of precipitation profiles for use ... -
Generation of an Eddy Dissipation Rate Map at the Hong Kong International Airport Based on Doppler Lidar Data
(American Meteorological Society, 2010)Turbulent airflow mostly occurs at Hong Kong International Airport (HKIA) when winds blow off the hills on the Lantau Island (with peaks rising to almost 1000 m to the south of the airport) from the east to the southwest. ... -
