File-format question with outputf to ASCII

Added by S Berendsen over 11 years ago

Hello all,

I've got some data in netCDF-files and need to convert it into a formatted-ASCII-file (isn't a gridbased file format, so can't export to it directly). The data itself in a regular grid with a time series of several decades for each grid point.

"cdo griddes" gave me the location of each grid point and "cdo outputf,%12.4g,42" an ASCII file with all the data.

Question:
What is the data order in the ASCII file?

I'm currently assuming:

- the time series for each point occurs consecutively
- allthe points in the xval-column in the "cdo griddes" output is being walked through once for each yval-entry (or given in pseudo-code:

for i in yval
   for j in xval
      for k in timesteps
         read data
      end
   end
end

Is this assumption correct?

Thank you in advance,

S. Berendsen

Each timestep contains all grid point values of the current timestep. The time loop is outside the ij loop:

for k in timesteps
   for i in yval
      for j in xval
         read data
      end
   end
end
