RISAn Improved Method to Derive Surface Albedo from Narrowband AVHRR Satellite Data: Narrowband to Broadband Conversion
Publisher: American Meteorological Society
Abstract: A method was investigated to estimate broadband surface shortwave albedo from the narrowband reflectances obtained by the Advanced Very High Resolution Radiometers (AVHRRs) on board the polar orbiting satellites. Field ...
Current Severe Accident Research and Development Topics for Wolsong PHWR Safety in Korea
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In Korea, pressurized heavy water-cooled reactors (PHWR) account for 17% of operating units and have taken an important role in providing national energy supply. The recent biggest issue in domestic PHWR community was the ...
Estimating Watershed Evapotranspiration with PASS. Part I: Inferring Root-Zone Moisture Conditions Using Satellite Data
Publisher: American Meteorological Society
Abstract: A model framework for parameterized subgrid-scale surface fluxes (PASS) has been modified and applied as PASS1 to use satellite data, models, and limited surface observations to infer root-zone available moisture (RAM) ...
Estimating Watershed Evapotranspiration with PASS. Part II: Moisture Budgets during Drydown Periods
Publisher: American Meteorological Society
Abstract: The second part of the parameterization of subgrid-scale surface fluxes model (PASS2) has been developed to estimate long-term evapotranspiration rates over extended areas at a high spatial resolution by using satellite ...
A Method to Determine Nonhydrostatic Effects within Subdomains in a Mesoscale Model
Publisher: American Meteorological Society
Abstract: The exact solution of the nonhydrostatic pressure residual (total pressure perturbation minus hydrostatic pressure perturbation) in Defant's linear model is derived. The quasi-nonhydrostatic residual, introduced by Pielke, ...
Evaluation of Cloud Shading Effects on the Generation and Modification of Mesoscale Circulations
Publisher: American Meteorological Society
Abstract: This study presents scale analysis and numerical model evaluations of the impact of cloud shading on 1) the development of sea breeze and thermally induced upslope flows and 2) the generation of mesoscale circulations ...
Estimating the Long-Term Hydrological Budget over Heterogeneous Surfaces
Publisher: American Meteorological Society
Abstract: Estimates of the hydrological budget in the Walnut River Watershed (WRW; ?5000 km2) of southern Kansas were made with a parameterized subgrid-scale surface (PASS) model for the period 1996?2002. With its subgrid-scale ...
Verification and Validation of SuperMC3.2 Using VENUS-3 Benchmark Experiments
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Methodological processes for nuclear power plant (NPP) pressure vessels' (PV) neutron fluence rate determination take the form of experimental measurement or theoretical calculations. However, the process of experimental ...
Study of Two Phase Natural Circulation Cooling of Core Catcher System Using Scaled Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A twophase natural circulation cooling has been proposed to remove melted core decay heat by external core catcher cooling system during sever accident scenario. In this paper, two types of the core catcher cooling loops, ...
The Doe Water Cycle Pilot Study
Publisher: American Meteorological Society
Abstract: A Department of Energy (DOE) multilaboratory Water Cycle Pilot Study (WCPS) investigated components of the local water budget at the Walnut River watershed in Kansas to study the relative importance of various processes ...
