RISPower and Propulsion at NASA Glenn Research Center: Historic Perspective of Major Accomplishments
Publisher: American Society of Civil Engineers
Abstract: Propulsion and power have long been core competencies of the National Aeronautics and Space Administration (NASA) Glenn Research Center (GRC). At the dawn of the space era, the center brought key propulsion and power ...
Laboratory Investigation of Ammonium and Nitrate Removal in Vertical-Flow Regimes in Planted and Unplanted Wetland Columns
Publisher: American Society of Civil Engineers
Abstract: Vertical-flow constructed wetlands were investigated for ammonium and nitrate removal from synthetic wastewater in bench-scale wetland columns. Total ammonia and nitrate were measured as wastewater and fed through planted ...
An Examination of Precipitation in Observations and Model Forecasts during NAME with Emphasis on the Diurnal Cycle
Publisher: American Meteorological Society
Abstract: Summertime rainfall over the United States and Mexico is examined and is compared with forecasts from operational numerical prediction models. In particular, the distribution of rainfall amounts is examined and the diurnal ...
New NGM-Based MOS Guidance for Maximum/Minimum Temperature, Probability of Precipitation, Cloud Amount, and Surface Wind
Publisher: American Meteorological Society
Abstract: In this paper, we describe the development and use of new nested grid model (NGM)-based model output statistics (MOS) guidance that has been available since 26 July 1989 for 204 stations in the contiguous United States. ...
Evaluating the Impact of RAFS Changes on the NGM-Based MOS Guidance
Publisher: American Meteorological Society
Abstract: In the spring of 1990, the National Meteorological Center (NMC) tested several modifications to the Regional Analysis and Forecast System (RAFS). In order to compare the proposed version of the RAFS to the current operational ...
