Improved Moments Estimation for VHF Active Phased Array Radar Using Fuzzy Logic Method
(American Meteorological Society, 2015)arious nonatmospheric signals contaminate radar wind profiler data, introducing bias into the moments and wind velocity estimation. This study applies a fuzzy logic?based method to Doppler velocity spectra to identify and ... -
Large-Eddy Simulation and Single-Column Modeling of Thermally Stratified Wind Turbine Arrays for Fully Developed, Stationary Atmospheric Conditions
(American Meteorological Society, 2015)ffects of atmospheric thermal stratification on the asymptotic behavior of very large wind farms are studied using large-eddy simulations (LES) and a single-column model for vertical distributions of horizontally averaged ... -
Continuous Daily Observation of the Marine Atmospheric Boundary Layer over the Kuroshio by a Helicopter Shuttle Service
(American Meteorological Society, 2014)his paper describes a new initiative in which in situ observations of the marine atmospheric boundary layer (MABL) are made by a helicopter shuttle connecting six islands south of Tokyo. This observation method aims to ... -
Description and Analysis of the Ocean Component of NOAA’s Operational Hurricane Weather Research and Forecasting Model (HWRF)
(American Meteorological Society, 2014)he Princeton Ocean Model for Tropical Cyclones (POM-TC), a version of the three-dimensional primitive equation numerical ocean model known as the Princeton Ocean Model, was the ocean component of NOAA?s operational Hurricane ... -
Intercomparison of Attenuation Correction Methods for the GPM Dual-Frequency Precipitation Radar

A 35-GHz Polarimetric Doppler Radar for Long-Term Observations of Cloud Parameters—Description of System and Data Processing
(American Meteorological Society, 2015)35-GHz radar has been operating at the Meteorological Observatory Lindenberg (Germany) since 2004, measuring cloud parameters continuously. The radar is equipped with a powerful magnetron transmitter and a high-gain antenna ... -
Nearshore Side-Scan Sonar Studies
(American Meteorological Society, 1993)Side-scan sonars operating at 80?250 kHz have been deployed to produce narrow beams directed parallel and normal to shore on a gently sloping beach. These provide measurements of processes (such as wave propagation) seaward ... -
Estimation of Winds from GPS Radio Occultations
(American Meteorological Society, 2014)PS radio occultations (RO) offer the possibility to map winds in the upper troposphere and lower stratosphere (UTLS) region because geopotential height is the independent coordinate of retrieval. Most other sounders do not ... -
Impact of Different Satellite Wind Lidar Telescope Configurations on NCEP GFS Forecast Skill in Observing System Simulation Experiments
(American Meteorological Society, 2014)he Global Wind Observing Sounder (GWOS) concept, which has been developed as a hypothetical space-based hybrid wind lidar system by NASA in response to the 2007 National Research Council (NRC) decadal survey, is expected ... -
Empirical Removal of Artifacts from the ISCCP and PATMOS-x Satellite Cloud Records
(American Meteorological Society, 2015)he International Satellite Cloud Climatology Project (ISCCP) dataset and the Pathfinder Atmospheres?Extended (PATMOS-x) dataset are two commonly used multidecadal satellite cloud records. Because they are constructed from ... -
Wind Measurements from Arc Scans with Doppler Wind Lidar
(American Meteorological Society, 2015)efining optimal scanning geometries for scanning lidars for wind energy applications remains an active field of research. This paper evaluates uncertainties associated with arc scan geometries and presents recommendations ... -
Removing Solar Radiative Effect from the VIIRS M12 Band at 3.7 μm for Daytime Sea Surface Temperature Retrievals
