Data Assimilation Using Incremental Analysis Updates
Publisher: American Meteorological Society
Abstract: The IAU (incremental analysis updating) process incorporates analysis increments into a model integration in a gradual manner. It does this by using analysis increments as constant forcings in a model's prognostic equations ...
A Multiyear Global Surface Wind Velocity Dataset Using SSM/I Wind Observations
Publisher: American Meteorological Society
Abstract: The Special Sensor Microwave Imagers (SSM/I) aboard three DMSP satellites have provided a large dataset of surface wind speeds over the global oceans from July 1987 to the present. These data are characterized by high ...
A Two-Dimensional Variational Analysis Method for NSCAT Ambiguity Removal: Methodology, Sensitivity, and Tuning
Publisher: American Meteorological Society
Abstract: In this study, a two-dimensional variational analysis method (2DVAR) is applied to select a wind solution from NASA Scatterometer (NSCAT) ambiguous winds. A 2DVAR method determines a ?best? gridded surface wind analysis ...
The Effects of Marine Winds from Scatterometer Data on Weather Analysis and Forecasting
Publisher: American Meteorological Society
Abstract: Satellite scatterometer observations of the ocean surface wind speed and direction improve the depiction of storms at sea. Over the ocean, scatterometer surface winds are deduced from multiple measurements of reflected ...
