Hi,
I am using the package ncdf to create netCDF files and I want to mimic the the header of an exiting netCDF file created outside of R. Below is what the existing header looks like (part of it that is different):

dimensions:
lat = 1974 ;
lon = 1894 ;

netCDF to TIFF
Greetings R users!
I am working with the ENSEMBLE climate data (10 min resolution daily
temperatures images for all of Europe 1950-2006). The data comes
packaged in a single netCDF file. I would like to read the data in and
export a subset (2002-2006) as geotiffs (one image per day). So far, I
can successfully read in the data and view the images within an R
display window. However, I have yet to

RNetCDF: retrieving variable names and units
Dear List,
does anybody has experience with the RNetCDF package? I manage to open a connection and copy data from a ncdf file but would need a way to automatically retrieve variable names (ideally all of them from one file) and units from the file.
Any ideas?

Help asked for automated generation of ncdf variables
Hi,
I'm using the "ncdf" library for creating ncdf files.
But I need to create about 100 variables per file (e.g. single rivers),
So I do not like to create each variable separately.
Unfortunately I found no way to make this work, as I'm unable to create a
correct list of class "var.ncdf".
