Comparison of Cloud Cover from All-Sky Imager and Meteorological Observer
(American Meteorological Society, 2012)aked-eye observation of cloud cover has widely resisted automation. Replacement of human observation by instruments is an inexorable trend for the development of ground-based macroscopic cloud observation. In this paper, ... -
A Comparison of Methods for Estimating Reynolds Stress from ADCP Measurements in Wavy Environments
(American Meteorological Society, 2011)urbulent Reynolds stresses are now routinely estimated from acoustic Doppler current profiler (ADCP) measurements in estuaries and tidal channels using the variance method, yet biases due to surface gravity waves limit its ... -
Mapping Bragg Scatter with a Polarimetric WSR-88D
(American Meteorological Society, 2011)sing a polarimetric Weather Surveillance Radar-1988 Doppler (WSR-88D) radar to distinguish Bragg scatterers from insects and birds in an optically clear atmosphere has the potential to provide information on convective ... -
Improved Liquid Water Equivalent Nowcasting Using the Weather Support to Deicing Decision Making System
(American Meteorological Society, 2011)hort-term automated forecasts (nowcasts) of liquid water equivalent (LWE) values can be used to assist aviation deicing decision-making activities. Such decisions can mitigate hazards that cause losses of life and property ... -
Atmospheric Temperature and Absolute Humidity Profiles over the Beaufort Sea and Amundsen Gulf from a Microwave Radiometer
(American Meteorological Society, 2012)Radiometrics MP-3000A microwave radiometric profiler (MWRP) provided high temporal resolution atmospheric profiles for temperature and absolute humidity up to 10 km, while 113 radiosondes were launched (and 68 were used ... -
An Extended Kalman Filter Framework for Polarimetric X-Band Weather Radar Data Processing
(American Meteorological Society, 2012)he different quantities measured by dual-polarization radar systems are closely linked to each other. An extended Kalman filter framework is proposed in order to make use of constraints on individual radar observables that ... -
A Quality-Control and Bias-Correction Method Developed for Irregularly Spaced Time Series of Observational Pressure Data
(American Meteorological Society, 2011)his paper presents a method to detect and correct occurring biases in observational mean sea level pressure (MSLP) data, which was developed within the Mesoscale Alpine Climate Dataset [MESOCLIM; i.e., 3-hourly MSLP, ... -
Using MetOp-A AVHRR Clear-Sky Measurements to Cloud-Clear MetOp-A IASI Column Radiances
(American Meteorological Society, 2011)igh spatial resolution measurements from the Advanced Very High Resolution Radiometer (AVHRR) on the Meteorological Operation (MetOp)-A satellite that are collocated to the footprints from the Infrared Atmospheric Sounding ... -
Development and Application of a Compact, Tunable, Solid-State Airborne Ozone Lidar System for Boundary Layer Profiling
(American Meteorological Society, 2011)he National Oceanic and Atmospheric Administration/Earth System Research Laboratory/Chemical Sciences Division (NOAA/ESRL/CSD) has developed a versatile, airborne lidar system for measuring ozone and aerosols in the boundary ... -
Comparison between the TOPAZ Airborne Ozone Lidar and In Situ Measurements during TexAQS 2006
(American Meteorological Society, 2011)he NOAA airborne ozone lidar system [Tunable Optical Profiler for Aerosol and Ozone (TOPAZ)] is compared with the fast-response chemiluminescence sensor flown aboard the NOAA WP-3D during the 2006 Texas Air Quality Study ... -
Trial of a Slant Visual Range Measuring Device
(American Meteorological Society, 1993)Each year fog at airports renders some landing operations either difficult or impossible. In such instances, visibility is the most important information for the pilot of a landing aircraft. Visibility may be constant, ... -
Airborne Measurement of Liquid and Total Water Content
(American Meteorological Society, 2011)wo identical liquid water content (LWC) King probes?one total water content/liquid water content (TWC/LWC) Nevzorov probe and two constant-temperature T probes that are different in size to distinguish particles of different ... -
Adaptive Range Oversampling to Achieve Faster Scanning on the National Weather Radar Testbed Phased-Array Radar
(American Meteorological Society, 2011)his paper describes a real-time implementation of adaptive range oversampling processing on the National Weather Radar Testbed phased-array radar. It is demonstrated that, compared to conventional matched-filter processing, ... -
Nocturnal Aerosol Optical Depth Measurements with a Small-Aperture Automated Photometer Using the Moon as a Light Source
(American Meteorological Society, 2011)method is described that enables the use of lunar irradiance to obtain nighttime aerosol optical depth (AOD) measurements using a small-aperture photometer. In this approach, the U.S. Geological Survey lunar calibration ... -
Concept Tests for a New Wire Flying Vehicle Designed to Achieve High Horizontal Resolution Profiling in Deep Water
(American Meteorological Society, 2011)fficiently profiling the water column to achieve both high vertical and horizontal resolution from a moving vessel in deep water is difficult. Current solutions, such as CTD tow-yos, moving vessel profilers, and undulating ... -
Intercomparison of Four Commercial Analyzers for Water Vapor Isotope Measurement
