View Full Version : High resolution wind

27th September 2005, 11:00 AM
Hi friends,
I am using a coastal ocean model, for which I need very high resolution forecast wind, preferably of ~10 km resolution. The domain is Indian coast. Does anyone know some agency which provides such high resolution wind data(u and v components) forecast free of cost or on payment?

I don't understand of winds, but I found this article
http://cimss.ssec.wisc.edu/itwg/itsc/itsc13/proceedings/session1/1_9_singh.pdf (http://cimss.ssec.wisc.edu/itwg/itsc/itsc13/proceedings/session1/1_9_singh.pdf)
referring to AMSU observations over Indian regions and wind data of the resolution you are looking for...
maybe they are provided by the India Meteorological Department (see the author)
or from a military based governamental department.
However, maybe you're looking for something more specific...good luck!

QuickSCAT scatterometer winds provides sattelite observed wind stress
and speed on 0.25x0.25 degree resolution (only from 1999 onwards)
Still this is only 25 km resoltion. I am not aware of any 10 km
resolution data sets. I hope, more information may be feeding
on this query.

TRMM/TMI satellite provide wind stress from 1997 onward (i am not quite
sure about the period), it is also 0.25x0.25 degree resolution.

for these data sets, please refere our Database forum (http://www.oceanographers.net/forums/forumdisplay.php?f=7).

If you are looking for any satellite derived wind vector product, I would rather suggest for QuikSCAT which measures wind vector with 0.25 x 0.25 earth grid that is apparently better than the other contemporary satellites. The dataset is available since July-99 to till date. Inorder to download the data, have a thorough look on the Remote Sensing Systems (RSS) website and/or in JPL physical oceanography DAAC (PODAAC) site. The data is being widely used as an input for ocean state forecasting. The data is available in public domain with a time lag of only few hours. If you need any program to read the data format or else you want any software to analyze and display the data, please feel free to contact.

With best regards

Dear friends,
Thank you for your response. But still I didn't get what I needed.The suggestions were to get from quikscat, but that is observational data. What I need is forecast data of nearly 10 km resolution.I want to forcast ocean waves for say, 2 days.For this I will need wind FORECAST for 2 days, not the past data.That is why quikscat data is of no use in my case.The requirement can be met only by some atmospheric model output. I found that NCEP has such a model-eta 10, which can give 10 km resolution wind forecast data.But they are not predicting wind for Indian coast.
Any further suggestion will be highly appreciated.
Thanks and regards,

Your purpose is well taken.

There is a 10 Km Global AGCM desingned in Earth Simulator. But
I am not sure whether they provide forecast outputs. The primary results
appeared recently,

Ohfuchi et al, (2004), 10-km Mesh Meso-scale Resolving simulation of the
Global atmosphere on the Earth Simulator- Preliminary outcomes of
AFES (AGCM for the Earth Simulator)., Jounral of the Earth Simulator,
Vol.1, 8-34. ( you can find the paper from the following link.)

If you communicate with them and enquire whether they provide
any forecaste data, that may help you.

Between, Did you contact NCMRWF/MM5 (Delhi)?
Do they have high-resolution forecast? They provide data
for public (free or paid)?
Also, CMMACS, have any regional model forecaste?
Please keep a search on that way.

I hope, more suggestions may be adding by our members who are familiar
with regional forecaste outputs.

Also, if you succeed to obtain the dataset from anywhere,
please feed back to this forum. That may worth a reference in future.

I wrote to NOAA and they have a model, eta 10 which can be used to forecast 10 km wind.But they have not sent me the code yet.They are not giving forecast in Indian ocean region.So we have to run the model here and get the forecast if needed.
I wrote to the author of the paper referred to by vinu, but didn't get a reply yet.
NCMRWF is not giving such a high resolution forecast.
If I get something in this regard, I will post it in this forum for sure.
