Problem to use this code

[javadbabagoli]

I try to download data for ROMS Rutgers. I can use it but I can download 10 variables. My other problem is the code does not change the time properly and my header file is for 1900. When I start running the model, I faced a problem.
netcdf era5_msnlwrf_year_2014 {
dimensions:
longitude = 36 ;
latitude = 29 ;
time = 4380 ;
variables:
float longitude(longitude) ;
longitude:units = "degrees_east" ;
longitude:long_name = "longitude" ;
float latitude(latitude) ;
latitude:units = "degrees_north" ;
latitude:long_name = "latitude" ;
int time(time) ;
time:units = "hours since 1948-01-01 00:00:00.0" ;
time:long_name = "time" ;
time:calendar = "gregorian" ;
short msnlwrf(time, latitude, longitude) ;
msnlwrf:scale_factor = 0.00339088604676628 ;
msnlwrf:add_offset = -91.074113655914 ;
msnlwrf:_FillValue = -32767s ;
msnlwrf:missing_value = -32767s ;
msnlwrf:units = "W m**-2" ;
msnlwrf:long_name = "Mean surface net long-wave radiation flux" ;

Have you ever encountered any problems while running ECMWF_tool.py?
I find a problem in it and will prevent the code to run to the normal end, which causes the absence of the process including changing unit and time.
Would you please post the result after running ECMWF_tool.py?
