I'm relatively new to Python and am trying to analyze an entire folder of netCDF files. When I try to run my code I get the key error: u'satcode'. Here is my code:
import netCDF4 as nc
import glob
import numpy as np
filenames = []
for name in glob.glob("/Users/my_name/Desktop/ISCCP/*"):
print name
filenames.append(name)
# below reads multiple files (file_list)
f = nc.MFDataset(filenames)
I know the error is with f = nc.MFDataset(filenames), but I don't know why.
My traceback says:
runfile('/Users/my_name/.spyder/West_Coast_Model.py', wdir='/Users/my_name/.spyder') /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGG.v01r00.GLOBAL.1983.07.01.0000.GPC.10KM.CS00.EA1.00 (5).nc /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGH.v01r00.GLOBAL.1983.07.99.0300.GPC.10KM.CS00.EA1.00.nc /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGH.v01r00.GLOBAL.1983.07.99.0600.GPC.10KM.CS00.EA1.00.nc /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGH.v01r00.GLOBAL.1983.07.99.0900.GPC.10KM.CS00.EA1.00.nc /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGH.v01r00.GLOBAL.1983.07.99.1200.GPC.10KM.CS00.EA1.00.nc /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGH.v01r00.GLOBAL.1983.07.99.1500.GPC.10KM.CS00.EA1.00.nc /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGH.v01r00.GLOBAL.1983.07.99.1800.GPC.10KM.CS00.EA1.00.nc /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGH.v01r00.GLOBAL.1983.07.99.2100.GPC.10KM.CS00.EA1.00.nc /Users/my_name/Desktop/ISCCP/ISCCP-Basic.HGH.v01r00.GLOBAL.1983.08.99.0000.GPC.10KM.CS00.EA1.00.nc Traceback (most recent call last):

I think I figured out the problem. The 0th term in the files was corrupted, so I redownloaded it and converted it into netCDF4_CLASSIC and it worked.
