Hi,
Do the "lat" and "lon" variables represent a grid? If so, then you need to define X and Y axes which correspond to the lon/lat data. This FAQ, http://ferret.pmel.noaa.gov/
Ferret/faq/reading-ascii-data- , though it discusses reading ASCII data, shows an example of defining axes using what is in lists of lat/lon values. Once you have defined the X-Y grid, then you'd use RESHAPE to put your data onto that grid. Pay attention to whether your data lists longitude varying fastest.representing-a-grid If the "lat" and "lon" variables represent scattered data, then you would define use one of the SCAT2GRID functions. To see a list of the options, type
yes? show function scat2grid*xy

Dear Ferret Users,
I am using ferret v 6.95 on Linux OS
I have a netcdf file with three different variables as "v1". "lat", "lon" on J-axisHow to regrid "v1" on i-axis & j-axis using "lat" and "lon". Data looks like below:

yes? use data.ncyes? sh dcurrently SET data sets:1> ./data.nc (default)name title I J K L M Nv1 var ... 1:1869 ... ... ... ...lat latitude ... 1:1869 ... ... ... ...lon longitude ... 1:1869 ... ... ... ...
Thanks,
