Hi Janine,

By McIDAS-formatted I assume you mean imagery in AREA format, or imagery 
that you can access through a McIDAS ADDE server.  In either case, McIDAS
can be used to do the conversion.

The procedure is:

- create an ADDE dataset in AREA format of the original GOES-11 images
  you want to convert

- create an output ADDE dataset in netCDF format

- use IMGCOPY to copy data from the input to the output datasets.  The
  format conversion is implicit

Here is a snippit from the online HELP for the DSSERVE command (DSSERVE
creates ADDE dataset definitions) on conversion to netCDF:

************************  netCDF Dataset Remarks  ************************
  ...

   You can create netCDF image files from other TYPE=IMAGE datasets. To
   do so, make a netCDF image dataset with a DSSERVE command similar to:
   DSSERVE ADD NETCDF/GOES NCDF 1 9999 TYPE=IMAGE "netCDF GOES image files
   Then specify NETCDF/GOES as the destination dataset with a positive
   position number in an IMGCOPY, IMGFILT, IMGOPER or IMGREMAP command.
   The output file name consists of the descriptor name and position
   number followed by ".nc". For example, the command
   IMGCOPY GOESEAST/VIS NETCDF/GOES.300 SIZE=ALL creates an output file
   named GOES0300.nc that's mapped to position 300 of dataset NETCDF/GOES.

If you have McIDAS available to use, then creating the input and output
datasets will take on the order of a minute.  You can then do as many
conversions as you need.

So, first question is if you have access to McIDAS?

> Thanks in advance,

No worries.


Cheers,

Tom
