Navy Fifth Fleet, Bahrain} Part I: Information Content and Retrieval Error Sensitivity To investigate the ability of an operational IR and MW atmospheric sounding system to contribute information to a mesoscale NWP system. within the summertime eastern Pacific (EPAC) environment.
Mesoscale Forecast System. 1DVAR profile temperature and humidity retrievals using both simulated and actual ATOVS observations constrained by the COAMPS™ short-term forecasts and synoptically relevant background errors
Mesoscale Forecast System. 1DVAR profile temperature and humidity retrievals using both simulated and actual ATOVS observations constrained by the COAMPS™ short-term forecasts and synoptically relevant background errors. The time period of interest coincided with the Dynamics and Chemistry of Marine Stratocumulus (DYCOMS) Phase II field study (July 2001).

Variational Retrieval of Eastern Pacific Atmospheric Boundary Layer Parameters Using ATOVS With th. .For this basin geometry the flow is mainly confined to the shelf, although a parameter regime is identified that supports significant flow in the deep basin.Cooper, Grant . IV. A one-dimensional variational (1DVAR) retrieval scheme is used to investigate the ability of the Advanced TIROS Operational Vertical Sounder (ATOVS) to contribute information to a mesoscale NWP system within tbe summertime Eastern Pacific (EPAC) environment.
The COAMPS mesoscale model used i.
The COAMPS mesoscale model used in. the present study is described in Hodur (1997). The model is nonhydrostatic and uses multiple.
Physical retrieval of atmospheric profiles from satellite observations is.
Physical retrieval of atmospheric profiles from satellite observations is sensitive to the uncertainty o.Compared with the regular temperature profile retrievals from the Atmospheric InfraRed Sounder (AIRS), the ensemble retrievals RMSE of temperature profiles selected by the PDF was reduced between 150 and 320 hPa and below 400 hPa, with a maximum improvement of . K at 400 hPa. The bias was also reduced in many layers, with a maximum improvement of . 9 K at 460 hPa. The combined optimal (CombOpt) profile and a mean optimal (MeanOpt) profile of all ensemble physical results were improved below 150 hPa.

The COAMPS inner domain is shown in Fig. 1 labeled with points of interest and geographical locations mentioned in the text. Marine boundary layer clouds at the heart of tropical. 1. Introduction and background internal and external platinum resistance temperature. The vertical grid distribution includes 30 levels with a minimum spacing of 10 m at the surface, 11 levels below . km, and the model top at ~31 km.
In meteorology, the planetary boundary layer (PBL), also known as the atmospheric boundary layer (ABL) or peplosphere, is the lowest part of the atmosphere and its behaviour is directly influenced by its contact with a planetary surface
In meteorology, the planetary boundary layer (PBL), also known as the atmospheric boundary layer (ABL) or peplosphere, is the lowest part of the atmosphere and its behaviour is directly influenced by its contact with a planetary surface. On Earth it usually responds to changes in surface radiative forcing in an hour or less.
Atmospheric boundary layers - nature theory and applications to environmental modelling and security. 2. Some modern features of boundary-layer meteorology - a birthday tribute for Sergej Zilitinkevich. Currently-used ux-prole relationships determining the lower boundary conditions in both mesoscale and larger scale models need to be rened.
