I would like to calculate the max and min of many netcdf files.
I know how to create one big array and then concatenate and find the
numpy.max but when I run this on 1000's of arrays I have a memory error.
What I would prefer is to loop through the arrays and produce the maximum
without having the make a big array.
My idea goes something like:
netCDF_list=[]
maxarray=[]
for dir in glob.glob(MainFolder + '*/01/')+ glob.glob(MainFolder +
'*/02/')+ glob.glob(MainFolder + '*/12/'):
for ncfile in glob.glob(dir + '*.nc'):
netCDF_list.append(ncfile)
for filename in netCDF_list:
ncfile=netCDF4.Dataset(filename)
TSFC=ncfile.variables['T_SFC'][:]
fillvalue=ncfile.variables['T_SFC']._FillValue
TSFC=MA.masked_values(TSFC, fillvalue)
for i in TSFC:
if i == N.max(TSFC, axis=0):
maxarray.append(i)
else:
pass
print maxarray
