python - Converting from netCDF4 to scipy.io netcdf -


i'm trying convert netcdf4 scipy.io netcdf web page program going onto doesn't have module netcdf4.

the program works in netcdf4 retrieving values file temperatures in degk giving me values such as:

[[ 258.77999878  258.77999878  258.77999878 ...,  258.77999878 258.77999878  258.77999878]  [ 259.29998779  259.54998779  259.82000732 ...,  258.3500061 258.70001221  258.97000122]  [ 264.1000061   264.47000122  264.82000732 ...,  262.40002441 263.04998779  263.6000061 ]].

however when using scipy.io netcdf , same file used in netcdf4. program runs should again give values of temperature in degk values come out as:

[[-25403 -25403 -25403 ..., -25403 -25403 -25403]  [-25351 -25326 -25299 ..., -25446 -25411 -25384]  [-24871 -24834 -24799 ..., -25041 -24976 -24921]].

i wondering if has come across problem before , how solve scipy.io netcdf program give same values.

first off, need distinguish wether reading netcdf-3 or netcdf-4 file. scipy.io.netcdf module can read netcdf-3, if it's netcdf-4 file, out of luck. not difference netcdf-4 files use hdf-5 file storage. said, looks read in something file, it's have netcdf-3 file.

if case, need "scale" , "offset" attributes on temperature variable , apply directly when using scipy.io.netcdf. netcdf-4-python module automagically looks these attributes , applies them 'behind scenes' you, why data ok when going through module.

cheers,

sean
