Error with nldas_hourly_refet.py caused by empty/incomplete NLDAS grb file

[mattyrb]

The error below was produced when a NLDAS grb was partially(?) downloaded. The file causing the error was 0kb in size, but had the appropriate naming convention. I suggest that we may have a check on NLDAS files that verifies that there is some data contained in the file.

I am getting same error. Did you fix it?

I don't think so because I am getting the same error with 2015 data. Maybe best to manually download that date where the first two files are 0 kb? I am going to try that and see if that resolves the issue. I submitted another issue request regarding this topic as well.

I fixed the error by manually downloading the two files. #81
