How to force the model after QuickScat?

#1 Unread post by LiuZHQ »

Dear All,
I'm doing some direct simulations of the circulations in western north Pacific Ocean using ROMS. After QuickSCAT retired, I can not find a very good wind speed/stress data to force my domain except some meteorologic model results, and some of my meteorology colleagues suggested the remote sensed ASCAT wind, however, I checked the data quality of this data, and there is some un-expected dis-continuity as I marked in the attached figure, and this kind of dis-continuity will excite disturbulence and contaminate my model results.

What I want to know is, what kind of wind data you're using after QuickSCAT?

All suggestions will be highly appreciated.

Hi,

You can try CCMP:
http://podaac.jpl.nasa.gov/DATA_CATALOG/ccmpinfo.html

Its not widely used as of yet. Not sure about quality, but its a blend of several satellite products and ECMWF forecasts.
My comparisons to buoy are very favorable though.
Note this is an analysis product. Also the time coverage is limited 90's something to 2009.

Sorry to revive an old thread, but it seems relevant. I want a reasonably high resolution (0.5 deg) surface stress dataset with global or Pacific Ocean coverage continuing to the present, more or less. (Aren't we all?)

CCMP, as suggested by saulo above, does seem to be a good product, but currently is available only to the end of 2011. (In the recent past, each year's data has been uploaded to the site in August of the following year, but it's November 2013 and 2012 has yet to appear.)

In March 2013 I downloaded several years of [url http://www.usgodae.org/pub/outgoing/fnm ... ls/nogaps/]NOGAPS[/url], but within a week of that they seem to have stopped extending the dataset.

NCAP Reanalysis is at very coarse resolution but the newer [url http://cfs.ncep.noaa.gov/]Climate Forecast System[/url] should be better.

What about ERA-Interim? The last time I looked at ECMWF surface stress data it showed a very marked temporal cycle, with the magnitudes increasing (I think) during each forecast period and then being reset at each analysis. Sorry I can't remember the details: it was a while ago.
