Re: [ferret_users] to produce surface contour from vertical section data sets?

[vijith v <vijithvnair@xxxxxxxxx>]

hi,
there is a maximum of 9 stations in a section. the stations doesn't have uniform depths. wot i did while computing dyn_ht was to remove those stations whose depth was less than 1000. the data is like this:
  name      title                             I         J         K               L
 TEM      Temperature              1:8       ...       1:1001    ...
 SAL      Salinity                       1:8       ...       1:1001    ...
 SIGH     Sigma-theta                1:8       ...       1:1001    ...
 LAT      Latitude                       1:8       ...         ...            ...
 LON      Longitude                   1:8       ...         ...            ...
thank you

Hi Vijith,

                 Handling  station/cruise data may not be straight forward always. Depending

on the situation, you can have quite different types of solution.  Will you please provide the

following details for a better solution?

1. Howmany stations (maximum) along a section
2. Does the data for a l lthe stations correspond to a sime time period?
        (so that ther eis only one time vaue)
3. Does the staions have acommon depth grid?

If we can get the data in proper shape first, we can either use the single argument
contour command or the 3-argument curvilinear version.

Let us see how we can solve it......

> hi,
> i am new to ferret. i have 8 different  vertical section data  files -  section_a.nc,  section_b.nc  etc. variable names tem, sal, density, lat,long are identical in all files. each section is oriented east west and are distributed from south to north. i calculated the dynamic height using ferret now i want to make a surface contour of dynamic height, since the data files are different  for different sections , i am unable to make any move forward using ferret. so i had to  use GMT after listing the variables.is there any way out in ferret..
