RISSome Characteristics of Time Interpolation Errors for Fluid Flows
Publisher: American Meteorological Society
Abstract: The size of errors due to linear time interpolation varies parabolically with a maximum at the center of the interpolation interval in most of the cases examined here. These cases include simple situations that are analyzed ...
An Introduction to the Near–Real–Time QuikSCAT Data
Publisher: American Meteorological Society
Abstract: The NASA Quick Scatterometer (QuikSCAT) satellite carries the SeaWinds instrument, the first satellite-borne scanning radar scatterometer. QuikSCAT, which was launched on 19 June 1999, is designed to provide accurate ocean ...
SeaWinds Validation: Effect of Rain as Observed by East Coast Radars
Publisher: American Meteorological Society
Abstract: To examine the accuracy of the SeaWinds scatterometer wind data and rain flags, and how this accuracy depends on ground-based radar-estimated rain rate, SeaWinds data, WSI NEXRAD precipitation rates, and selected Eta ...
Impact of NSCAT Winds on Tropical Cyclones in the ECMWF 4DVAR Assimilation System
Publisher: American Meteorological Society
Abstract: The impact of NASA Scatterometer (NSCAT) data on tropical cyclone forecasting on the European Centre for Medium-Range Weather Forecasts four-dimensional variational (4DVAR) data assimilation system is examined. Parallel ...
Improving Short-Term Numerical Weather Prediction in the California Coastal Zone by Dynamic Initialization of the Marine Boundary Layer
Publisher: American Meteorological Society
Abstract: Few data are available over the world?s oceans to characterize the initial atmospheric state in numerical models. Objective analysis in these regions is largely based on forecast fields obtained from a global model and ...
Impact of CYGNSS-Derived Winds on Tropical Cyclone Forecasts in a Global and Regional Model
Publisher: American Meteorological Society
Development and Application of a Visible–Infrared Rain Flag for Scatterometer Data
Publisher: American Meteorological Society
Abstract: The authors report on characteristics of a rain flag derived from collocation of visible and infrared image data with rain rates over the North Atlantic Ocean obtained from microwave imagery (SSM/I) during a 3-week period ...
A Severe Weather Quick Observing System Simulation Experiment (QuickOSSE) of Global Navigation Satellite System (GNSS) Radio Occultation (RO) Superconstellations
Publisher: American Meteorological Society
Abstract: lobal Navigation Satellite System (GNSS) radio occultations (RO) over the last 10 years have proved to be a valuable and essentially unbiased data source for operational global numerical weather prediction. However, the ...
Assimilation of Tropical Cyclone Observations: Improving the Assimilation of TCVitals, Scatterometer Winds, and Dropwindsonde Observations
Publisher: American Meteorological Society
Abstract: he standard statistical model of data assimilation assumes that the background and observation errors are normally distributed, and the first- and second-order statistical moments of the two distributions are known or can ...
Error Estimates for Ocean Surface Winds: Applying Desroziers Diagnostics to the Cross-Calibrated, Multiplatform Analysis of Wind Speed
Publisher: American Meteorological Society
Abstract: he Desroziers diagnostics (DD) are applied to the cross-calibrated, multiplatform (CCMP) ocean surface wind datasets to estimate wind speed errors of the ECMWF background, the microwave satellite observations, and the ...
