RISHindcasting the January 2009 Arctic Sudden Stratospheric Warming with Unified Parameterization of Orographic Drag in NOGAPS. Part II: Short-Range Data-Assimilated Forecast and the Impacts of Calibrated Radiance Bias Correction
Publisher: American Meteorological Society
Abstract: his study is Part II of the effort to improve the forecasting of sudden stratospheric warming (SSW) events by using a version of the Navy Operational Global Atmospheric Prediction System (NOGAPS) that covers the full ...
Accounting for Correlated Observation Error in a Dual-Formulation 4D Variational Data Assimilation System
Publisher: American Meteorological Society
Abstract: ppropriate specification of the error statistics for both observational data and short-term forecasts is necessary to produce an optimal analysis. Observation error stems from instrument error, forward model error, and ...

A Quality Control Procedure Based on Bending Angle Measurement Uncertainty for Radio Occultation Data Assimilation in the Tropical Lower Troposphere
Publisher: American Meteorological Society
Abstract: AbstractThe fluctuation of radio occultation (RO) signals in the presence of refractivity irregularities in the moist lower troposphere results in uncertainties of retrieved bending angle and refractivity profiles. In this ...

High-Altitude (0–100 km) Global Atmospheric Reanalysis System: Description and Application to the 2014 Austral Winter of the Deep Propagating Gravity Wave Experiment (DEEPWAVE)
Publisher: American Meteorological Society
Abstract: AbstractA data assimilation system (DAS) is described for global atmospheric reanalysis from 0- to 100-km altitude. We apply it to the 2014 austral winter of the Deep Propagating Gravity Wave Experiment (DEEPWAVE), an ...
