RISDeep Velocity Profiling with Self-contained ADCPs
Publisher: American Meteorological Society
Abstract: Ocean deep velocity profiles were obtained by lowering a self-contained 153.6-kHz acoustic Doppler current profiler (ADCP) attached to a CTD-rosette sampler. The data were sampled during two Meteor cruises in the western ...
Retrieval of Cloud Microphysical Properties from Thermal Infrared Observations by a Fast Iterative Radiance Fitting Method
Publisher: American Meteorological Society
Abstract: An algorithm is presented for inferring the IR optical depth, effective radius, and liquid water path of clouds from multispectral observations of emitted thermal radiation, which takes advantage of the larger number of ...
Detection of Cloud-Top Height from Backscattered Radiances within the Oxygen A Band. Part 1: Theoretical Study
Publisher: American Meteorological Society
Abstract: A series of radiative transfer calculations were performed to study the possibility of determining cloud-top pressure (height) from backscattered solar radiances within the oxygen A-band absorption. For the development of ...
Remote Sensing of Atmospheric Water Vapor from Backscattered Sunlight in Cloudy Atmospheres
Publisher: American Meteorological Society
Abstract: The ?differential absorption technique? is used to derive columnar water vapor contents above clouds. Radiative transfer simulations were carried out for two different spectral channels, one channel within the ?στ?water ...
A Synoptic Map of Isopycnic Potential Vorticity in the Seasonal Thermocline
Publisher: American Meteorological Society
Abstract: The distribution of isopycnic potential vorticity (IPV) has been mapped in the seasonal thermocline from a single ship using relative velocity measurements plus absolute ship motion, and density profiles from a CTD mounted ...
Thermohaline Finestructure and Its Relation to Frontogenesis Dynamics
Publisher: American Meteorological Society
Abstract: We present and compare results from a two-dimensional numerical frontogenesis model and a field experiment in the eddy field of the North Atlantic Current in order to illustrate and explain the shape and generation mechanisms ...
On the Use of Geophysical Parameters for the Top-of-Atmosphere Shortwave Clear-Sky Radiance-to-Flux Conversion in EarthCARE
Publisher: American Meteorological Society
Abstract: AbstractWe have investigated whether differences across Clouds and the Earth?s Radiant Energy System (CERES) top-of-atmosphere (TOA) clear-sky angular distribution models, estimated separately over regional (1° ? 1° ...
Remote Sensing of Atmospheric Water Vapor Using the Moderate Resolution Imaging Spectroradiometer
Publisher: American Meteorological Society
Abstract: This paper presents first validation results for an algorithm developed for the retrieval of integrated columnar water vapor from measurements of the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on board ...
The CM-SAF and FUB Cloud Detection Schemes for SEVIRI: Validation with Synoptic Data and Initial Comparison with MODIS and CALIPSO
Publisher: American Meteorological Society
Abstract: The Satellite Application Facility on Climate Monitoring (CM-SAF) is aiming to retrieve satellite-derived geophysical parameters suitable for climate monitoring. CM-SAF started routine operations in early 2007 and provides ...
Detection of Cloud-Top Height from Backscattered Radiances within the Oxygen A Band. Part 2: Measurements
Publisher: American Meteorological Society
Abstract: Cloud-top heights were successfully derived from reflected solar radiation measurements within the oxygen A-band absorption. The accuracy of the estimated cloud-top heights was to within 40 meters over stratus clouds when ...
