Comparison of Turbulence Intensity from CTD-Attached and Free-Fall Microstructure Profilers
(American Meteorological Society, 2017)AbstractTurbulence intensity estimated from fast-response thermistors is compared between conductivity?temperature?depth (CTD)-attached and free-fall microstructure profilers, conducted at the same location within 2 h. The ... -
Monte Carlo Study of UAV-Measurable Albedo over Arctic Sea Ice
(American Meteorological Society, 2017)AbstractIn anticipation that unmanned aerial vehicles (UAVs) will have a useful role in atmospheric energy budget studies over sea ice, a Monte Carlo model is used to investigate three-dimensional radiative transfer over ... -
Do Nonorthogonally and Irregularly Sampled Scalar Velocities Contain Sufficient Information to Reconstruct an Orthogonal Vector Current Field?
(American Meteorological Society, 2018)AbstractThis paper addresses how well a two-dimensional orthogonal vector current field can be reconstructed from a set of nonorthogonally and irregularly sampled scalar velocity data. High-frequency radar (HFR)-derived ... -
Coherent Power Measurements with a Compact Airborne Ka-Band Precipitation Radar
(American Meteorological Society, 2017)AbstractCoherent power is an alternative to the conventional noise-subtracted power technique for measuring weather radar signal power. The inherent noise-canceling feature of coherent power eliminates the need for estimating ... -
On Some Shortcomings of Shannon Entropy as a Measure of Information Content in Indirect Measurements of Continuous Variables
(American Meteorological Society, 2018)AbstractShannon entropy has long been accepted as a primary basis for assessing the information content of sensor channels used for the remote sensing of atmospheric variables. It is not widely appreciated, however, that ... -
Efficient Methods to Account for Cloud-Top Inclination and Cloud Overlap in Synthetic Visible Satellite Images
(American Meteorological Society, 2018)AbstractVisible satellite images contain high-resolution information about clouds that would be well suited for convective-scale data assimilation. This application requires a forward operator to generate synthetic images ... -
Hourly Observed Internal Waves by Geostationary Ocean Color Imagery in the East/Japan Sea
(American Meteorological Society, 2018)AbstractAs internal waves (IWs) are generated via internal tidal energy near the bottom shelf break of the Korea Strait, continuous evolutions of IWs are extremely difficult to observe using satellite observations. However, ... -
A Methodology to Determine Recipe Adjustments for Multispectral Composites Derived from Next-Generation Advanced Satellite Imagers
(American Meteorological Society, 2018)AbstractThe European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) began creating multispectral [i.e., red?green?blue (RGB)] composites in the early 2000s with the advent of the Meteosat-8 ... -
The KLIWAS North Sea Climatology. Part II: Assessment against Global Reanalyses
(American Meteorological Society, 2017)AbstractObservational reference datasets are needed in atmosphere and ocean for quality assessments of climate models and for the evaluation of atmospheric reanalyses. To meet this demand on the regional scale, the Climate ... -
Mitigating VHF Lightning Source Retrieval Errors
(American Meteorological Society, 2018)AbstractThe problem of inferring the location and time of occurrence of a very high frequency (VHF) lightning source emission from Lightning Mapping Array (LMA) network time-of-arrival (TOA) measurements is closely examined ... -
The KLIWAS North Sea Climatology. Part I: Processing of the Atmospheric Data
(American Meteorological Society, 2017)AbstractClimatological reference data serve as validation of regional climate models, as the boundary condition for the model runs, and as input for assimilation systems used by reanalyses. Within the framework of the ... -
Autonomous Sampling of Ocean Submesoscale Fronts with Ocean Gliders and Numerical Model Forecasting
(American Meteorological Society, 2018)ABSTRACTSubmesoscale fronts arising from mesoscale stirring are ubiquitous in the ocean and have a strong impact on upper-ocean dynamics. This work presents a method for optimizing the sampling of ocean fronts with autonomous ... -
Estimation of Rain Rate from Airborne Doppler W-Band Radar in CalWater-2
(American Meteorological Society, 2017)ABSTRACTThe NOAA W-band radar was deployed on a P-3 aircraft during a study of storm fronts off the U.S. West Coast in 2015 in the second CalWater (CalWater-2) field program. This paper presents an analysis of measured ... -
Use of an End-to-End-Simulator to Analyze CYGNSS
(American Meteorological Society, 2017)AbstractTropical convection during the onset of two Madden?Julian oscillation (MJO) events, in October and December of 2011, was simulated using the Weather Research and Forecasting (WRF) Model. Observations from the ... -
