RISMultichannel Microwave Radiometric Observations at Saipan during the 1990 Tropical Cyclone Motion Experiment
Publisher: American Meteorological Society
Abstract: To estimate mesoscale variations in integrated water vapor, cloud liquid water, and temperature in a tropical region, multiwavelength microwave radiometric observations were carried out over a seven-week period on the ...
Remote Sensing of Tropospheric Water Vapor and Cloud Liquid Water by Integrated Ground-Based Sensors
Publisher: American Meteorological Society
Abstract: A technique is presented for deriving tropospheric water vapor and cloud liquid water, as well as temperature, from a suite of ground-based sensors. Included in the suite are a dual-channel microwave radiometer, a ceilometer, ...
Interaction Between the Torsional Vibration of a Circular Rod and an Adjacent Viscous Fluid
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the effect of an adjacent viscous fluid on the torsional vibration of a circular rod excited by a transducer at one end. The interaction between the torsional vibration ...
Influence Mechanism of Trimming Impeller Diameter in a Centrifugal Pump by Computational Fluid Dynamics Investigation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Trimming the impeller diameter of a centrifugal pump is the easiest and most economical way to adjust its efficient operating range based on its original performance. Three impellers obtained by trimming the diameter are ...
Servo System Identification Based on Curve Fitting to Phase-Plane Trajectory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many methods have been proposed to identify servo system parameters. However, problems still remain in widely applied offline identification methods, for example, the describing-function-based relay feedback method has the ...
Global Oceanic Precipitation Derived from TOPEX and TMR: Climatology and Variability
Publisher: American Meteorological Society
Abstract: A detailed study on global oceanic precipitation is carried out using the simultaneous TOPEX and TMR (TOPEX Microwave Radiometer) data. It is motivated by the success of a series of feasibility studies based on a few years ...
Assessment of Shortwave Infrared Sea Surface Reflection and Nonlocal Thermodynamic Equilibrium Effects in the Community Radiative Transfer Model Using IASI Data
Publisher: American Meteorological Society
Abstract: he nadir-viewing satellite radiances at shortwave infrared channels from 3.5 to 4.6 ?m are not currently assimilated in operational numerical weather prediction data assimilation systems and are not adequately corrected ...
Planck-Weighted Transmittance and Correction of Solar Reflection for Broadband Infrared Satellite Channels
Publisher: American Meteorological Society
Abstract: he line-by-line radiative transfer model (LBLRTM) is used to derive the channel transmittances. The channel transmittance from a level to the top of the atmosphere can be approximated by three methods: Planck-weighted ...
Effect of Out-of-Band Response in NOAA-16 AVHRR Channel 3b on Top-of-Atmosphere Radiances Calculated with the Community Radiative Transfer Model
Publisher: American Meteorological Society
Abstract: The Community Radiative Transfer Model (CRTM) developed at the Joint Center for Satellite Data Assimilation (JCSDA) is used in conjunction with a daily sea surface temperature (SST) and the National Centers for Environmental ...
Community Radiative Transfer Model for Stratospheric Sounding Unit
Publisher: American Meteorological Society
Abstract: o better use the Stratospheric Sounding Unit (SSU) data for reanalysis and climate studies, issues associated with the fast radiative transfer (RT) model for SSU have recently been revisited and the results have been ...
