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
