RISThe Ensemble Tangent Linear Model Applied to Nonorographic Gravity Wave Drag
Publisher: American Meteorological Society
Measurements of the Marine Boundary Layer from an Airship
Publisher: American Meteorological Society
Abstract: In 1992 and 1993, the authors made measurements of the marine boundary layer off the coast of Oregon from an airship. In 1992, these measurements consisted of coherent microwave backscatter measurements at Ku band taken ...
Mixing and Chemical Ozone Loss during and after the Antarctic Polar Vortex Major Warming in September 2002
Publisher: American Meteorological Society
Abstract: The 3D version of the Chemical Lagrangian Model of the Stratosphere (CLAMS) is used to study the transport of CH4 and O3 in the Antarctic stratosphere between 1 September and 30 November 2002, that is, over the time period ...

First Application of the Local Ensemble Tangent Linear Model (LETLM) to a Realistic Model of the Global Atmosphere
Publisher: American Meteorological Society
Abstract: AbstractThe local ensemble tangent linear model (LETLM) provides an alternative method for creating the tangent linear model (TLM) and adjoint of a nonlinear model that promises to be easier to maintain and more computationally ...

Hybrid 4DVAR with a Local Ensemble Tangent Linear Model: Application to the Shallow-Water Model
Publisher: American Meteorological Society
Abstract: n ensemble-based tangent linear model (TLM) is described and tested in data assimilation experiments using a global shallow-water model (SWM). A hybrid variational data assimilation system was developed with a 4D variational ...
Evaluation of SSMIS Upper Atmosphere Sounding Channels for High-Altitude Data Assimilation
Publisher: American Meteorological Society
Abstract: pper atmosphere sounding (UAS) channels of the Special Sensor Microwave Imager/Sounder (SSMIS) were assimilated using a high-altitude version of the Navy Global Environmental Model (NAVGEM) in order to investigate their ...
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 ...
