NetCDF to ascii file

[Arnaud Vandecasteele]

Hi all,

I would like to know if it's possible to read data from a netcdf file and
export it into an ASCII file.
I'm trying to get the latitude, longitude and a determinate value of a
netcdf file. But I don't know exactly how to do it.
I succeed to open and read a netcdf file but i don't know how to export the
data.
Here is my simple script :

import Scientific.IO.NetCDF as nc
from Numeric import *
import sys

try :
    ncFile = nc.NetCDFFile("tos_O1_2001-2002.nc","r")
except :
    print "can't open the file"
    sys.exit(1)

try :
    print "################# Dimensions #################"
    print ncFile.dimensions.keys()

    print "################# Variables #################"
    print ncFile.variables.keys()
    #return ['time_bnds', 'lat_bnds', 'lon', 'lon_bnds', 'time', 'lat',
'tos'

    print "################# Var Dim #################"
    tos = ncFile.variables["tos"]
    print tos.dimensions
    #return : ('time', 'lat', 'lon')


    tosValue = tos.getValue()

except :
    ncFile.close()



Do you know how I can get for each tos feature the lat, lon and time values.

Best regards

Arnaud
