Re: how to obtain geostrophic velocity

Hi
xuhuacheng,

I can see that you are using data producted by Collecte
Localisation Satellites
(.\hh_msla_oer_merged_h_15655.nc).

First, you are using Ferret for the analyse and visualisation of your
data. 
Ferret is an OPeNDAP client, so you can use the AVISO OPeNDAP server to
access the data of Jason, T/P, Envisat, GFO etc... remotly
(http://opendap.aviso.oceanobs.com).

Another way to access these data is the AVISO Live Access Server
(http://las.aviso.oceanobs.com).
This software use Ferret as back-end application. You can use it to plot
rapidly the data, and use the different functionnality of the
LAS.

For the scientific question, aviso@cls.fr is the good adress, and this
mail is in copy.

If you have ohter question, do not hesitate.

Best regards, Tony Jolibois

Hi ferreters!
   I would like to use T/P altimeter data to obtain geostrophic velocity.The following are the introduction of the data and the formula to be used.
 
yes? show data

           How can I use the data to obtain the geostrophic velocity.Any information will  be highly appreciated.
