Dear Gradsusr support team,

I would like to open the attached netcdf file, however, it is giving errors
in GrADS. I downloaded this attached netcdf file from the following link
https://data.giss.nasa.gov/modelforce/strataer/ (this belongs to 2nd figure
on this page).

I tried to open it using ctl file, however, couldn't get it working.
Following is the output of ncdump -h command:

ncdump -h tau_map_2012-12.nc
netcdf tau_map_2012-12 {
dimensions:
level = 4 ;
lat = 24 ;
month = 1956 ;
bnds = 2 ;
variables:
float level(level) ;
level:long_name = "level" ;
level:units = "km" ;
level:positive = "up" ;
level:bnds = "level_bnds" ;
float level_bnds(level, bnds) ;
float lat(lat) ;
lat:long_name = "latitude" ;
lat:standard_name = "latitude" ;
lat:units = "degrees_north" ;
int month(month) ;
month:long_name = "middle day in month" ;
month:units = "days since 1850-01-01 00:00:00" ;
month:bounds = "month_bnds" ;
int month_bnds(month, bnds) ;
int tau_lvl(month, level, lat) ;
tau_lvl:long_name = "zonal mean aerosol optical depth of level at 550 nm" ;
tau_lvl:scale_factor = 0.0001 ;
tau_lvl:add_offset = 0. ;
tau_lvl:_FillValue = 9999 ;
int tau(month, lat) ;
tau:long_name = "zonal mean stratospheric aerosol optical depth at 550 nm" ;
tau:scale_factor = 0.0001 ;
tau:add_offset = 0. ;
tau:_FillValue = 9999 ;

// global attributes:
:Conventions = "CF-1.1" ;
:title = "Stratospheric Aerosol Optical Depth at 550 nm" ;
:institution = "NASA Goddard Institute for Space Sciences" ;
:source = "http://data.giss.nasa.gov/modelforce/strataer/" ;
:history = "Converted from ASCII file tau.map_2012.12.txt to netCDF on
2016-11-14. / rbs" ;
}

Could you kindly help me how can I open it and get it working?
Thank you and best regards,

Mubashar
