Variational Data Assimilation for Determining the Seasonal Net Surface Heat Flux Using a Tropical Pacific Ocean Model
sea surface temperature Tropical Pacific Ocean Model surface heat flux
2008/12/12
The authors present a study for determining the seasonal net surface heat flux over the tropical Pacific Ocean using an adjoint technique. A simple tropical ocean model with thermodynamics is chosen a...

quasigeostrophic North Atlantic Ocean Geosat Data Assimilation
2008/11/11
An attempt is made to determine the three-dimensional ocean circulation from satellite altimeter measurements by assimilating Geosat sea surface height data into an eddy-resolving quasigeostrophic (QG...
An Ensemble Kalman Filter for severe dust storm data assimilation over China
Ensemble Kalman Filter dust storm China
2008/11/10
An Ensemble Kalman Filter (EnKF) data assimilation system was developed for a regional dust transport model. This paper applied the EnKF method to investigate modeling of severe dust storm episodes oc...

Ocean Data Global Upper Ocean
2008/6/30
The authors explore the accuracy of a comprehensive 46-year retrospective analysis of upper-ocean temperature, salinity, and currents. The Simple Ocean Data Assimilation (SODA) analysis is global, spa...
Balanced Ocean-Data Assimilation near the Equator
Balanced Ocean-Data Assimilation Equator
2008/6/16
The question is addressed whether using unbalanced updates in ocean-data assimilation schemes for seasonal forecasting systems can result in a relatively poor simulation of zonal currents. An assimila...
Marine geochemical data assimilation in an efficient Earth System Model of global biogeochemical cycling
Marine geochemical data assimilation Earth System Model global biogeochemical cycling
2010/1/14
We have extended the 3-D ocean based "Grid ENabled Integrated Earth system model" (GENIE-1) to help understand the role of ocean biogeochemistry and marine sediments in the long-term (~100 to 100 000 ...
