RISRetrieval of Atmospheric Temperature Profiles from AMSU-A Measurement Using a Neural Network Approach
Publisher: American Meteorological Society
Abstract: Backpropagation neural networks are applied to retrieve atmospheric temperature profiles and tropopause variables from the NOAA-15 Advanced Microwave Sounding Unit-A (AMSU-A) measurement based on two different data sources. ...
Reactivity Accident in a High Temperature Gas-Cooled Reactor Due to Inadvertent Withdrawal of Control Rod
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Reactivity accident due to inadvertent withdrawal of the control rod is one kind of the design basis accident for high temperature gas-cooled reactors, which should be analyzed carefully in ...
Surface Forcing of the Infrared Cooling Profile over the Tibetan Plateau. Part I: Influence of Relative Longwave Radiative Heating at High Altitude
Publisher: American Meteorological Society
Abstract: The role of the Tibetan Plateau on the behavior of the surface longwave radiation budget is examined, and the behavior of the vertical profile of longwave cooling over the plateau, including its diurnal variation, is ...
Surface Forcing of the Infrared Cooling Profile over the Tibetan Plateau. Part II: Cooling-Rate Variation over Large-Scale Plateau Domain during Summer Monsoon Transition
Publisher: American Meteorological Society
Abstract: During the summer east Asian monsoon transition period in 1979, a meteorological field experiment entitled the Qinghai-Xizang Plateau Meteorological Experiment (QXPMEX-79) was conducted over the entire Tibetan Plateau. ...
An Adaptive Response Surface Method Using Bayesian Metric and Model Bias Correction Function
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Bayesian metric was used to select the best available response surface in the literature. One of the major drawbacks of this method is the lack of a rigorous method to quantify data uncertainty, which is required as ...
Scene Radiance–Dependent Intersatellite Biases of HIRS Longwave Channels
Publisher: American Meteorological Society
Abstract: Measurements from the simultaneous nadir overpass (SNO) observations of the High Resolution Infrared Radiation Sounder (HIRS) are examined. The SNOs are the measurements taken at the orbital intersections of each pair of ...
Sound Radiation From Point Acoustic Sources With Shield of Large Prolate Spheroidal Baffles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sound radiation from stationary and rotating point acoustic sources with shield of rigid prolate spheroidal baffles is explored in the prolate spheroidal coordinate system. The formulae of far-field sound pressure and ...
