Join us for this week's Physical Oceanography Seminar, featuring GSO professor Peter Cornillon.
Title: Estimating the Circulation & Climate of the Ocean (ECCO) — The Good, the Bad and...
Abstract:
ECCO was established in 1999 with the goal of combining a general circulation model (GCM) with diverse observations in order to produce a quantitative depiction of the time-evolving global ocean state. The model and its derivatives have been run on the global ocean in a number of configurations — spatial resolutions and temporal ranges. The highest resolution version is referred to as llc-4320 with a spatial resolution of 1/48th of a degree (~2 km at the Equator), 90 levels in the vertical and hourly output. This version of the model has been run for a two year period starting in late 2011. It is forced with observed winds and solar insolation and it has real tides. It is a free-running model; i.e., it does not assimilate oceanographic fields. The group at JPL that undertook the llc-4320 run is now working on a fully coupled (atmosphere-ocean) version. Initial funding for the model was through NOPP and use of the model output was one of the 3 main foci of NASA's 2018 Physical Oceanography call for proposals. The bottom line is that the model is being used extensively in a broad range of ocean studies. In this presentation I address one small element of the model — the location of the Gulf Stream. The question I asked is ‘How well is the model doing in this regard?’ Well, to find out you will have to come to this 30 minute seminar, a brief summary of my first 6 weeks at JPL.
