I have daily GRIB data which I want to extract their subdataset and convert the result to .tif files. I wrote a code in python but I received this erroe:
"Traceback (most recent call last):
File "D:/NASA/Data/SPoRT LIS/Extract-subdata.py", line 24, in <module>
for raster in rasterList:
TypeError: 'NoneType' object is not iterable"
What is my code's problem? Your help is really appreciated.
