Assessment of Quality and Reliability of Measurements with XBT Sippican T5 and T5/20
(American Meteorological Society, 2018)AbstractThe T5 expendable bathythermographs reach the greatest depth within the current XBT family. Since the early 1970s, in several areas they have been providing a significant part of available temperature profiles below ... -
A Quantitative Method to Evaluate Tropical Cyclone Tracks in Climate Models
(American Meteorological Society, 2018)AbstractThe ability to simulate tropical cyclones (TCs) realistically is an important factor in the performance evaluation of climate models. In previous studies, indirect evaluation methods have been proposed that are ... -
Investigation of Sand Ripple Dynamics with Combined Particle Image and Tracking Velocimetry
(American Meteorological Society, 2018)AbstractAccurately assessing the response of sediments to oscillatory flows requires high-resolution fluid velocity and sediment transport measurements at the fluid?sediment interface. Fluid and sediment grain velocities ... -
Retrieving Global Wilson Currents from Electrified Clouds Using Satellite Passive Microwave Observations
(American Meteorological Society, 2018)AbstractHigh-altitude atmospheric electricity measurements have been used to calculate the conduction (Wilson) currents that are supplied to the global electric circuit (GEC) by individual electrified clouds. Quantifying ... -
Polarimetric Radar Signatures of a Rare Tornado Event over South Korea
(American Meteorological Society, 2018)AbstractThe Korea Institute of Civil Engineering and Building Technology (KICT) made one of the first radar observations of a rare tornadic storm that occurred on 10 June 2014 in the Seoul metropolitan region, South Korea, ... -
An Updated Estimate of Salinity for the Atlantic Ocean Sector Using Temperature–Salinity Relationships
(American Meteorological Society, 2018)AbstractSimultaneous temperature and salinity profile measurements are of extreme importance for research; operational oceanography; research and applications that compute content and transport of mass, heat, and freshwater ... -
The Optical Autocovariance Wind Lidar. Part II: Green OAWL (GrOAWL) Airborne Performance and Validation
(American Meteorological Society, 2018)AbstractA two-look airborne Doppler wind lidar operating at the 532-nm laser wavelength, the Green Optical Autocovariance Wind Lidar (GrOAWL), was built and flown aboard the NASA WB-57 research aircraft. Flight campaign ... -
A Generalized Navigation Correction Method for Airborne Doppler Radar Data
(American Meteorological Society, 2018)AbstractUncertainties in aircraft inertial navigation system and radar-pointing angles can have a large impact on the accuracy of airborne dual-Doppler analyses. The Testud et al. (THL) method has been routinely applied ... -
The Impact of Sensor Response and Airspeed on the Representation of the Convective Boundary Layer and Airmass Boundaries by Small Unmanned Aircraft Systems
