[gradsusr] [Possibly Spoofed] Plotting GOES 16 imagery

[M.Mahakur]

Hi, 

Data is not in regular lat-lon grid. I believe GrADS cannot handle this data. 

Best Regards, 
Mahakur

Hello, I'm trying to plot GOES 16 retrievals of downward shortwave 
radiation. The file is netcdf. sdfopen tells me I need to use a control 
file with an xdef. I don't believe I have enough information to plot the 
data correctly. I would like to know if anyone has plotted GOES 16 data 
with grads? Is there something from the header of the nc file that would 
help? The header information is below. 

dimensions: 
columns = 5424 ; 
rows = 5424 ; 
variables: 
float Lon(rows, columns) ; 
Lon:_FillValue = -999.999f ; 
Lon:long_name = "Longitude" ; 
Lon:standard_name = "longitude" ; 
Lon:units = "degrees_east" ; 
Lon:valid_range = -180.f, 180.f ; 
float Lat(rows, columns) ; 
Lat:_FillValue = -999.999f ; 
Lat:long_name = "Latitude" ; 
Lat:standard_name = "latitude" ; 
Lat:units = "degrees_north" ; 
Lat:valid_range = -90.f, 90.f ; 

float DSR(rows, columns) ; 
DSR:_FillValue = -999.999f ; 
DSR:long_name = "Downward Shortwave Radiation at surface" ; 
DSR:standard_name = 
"surface_downwelling_shortwave_flux_in_air" ; 
DSR:units = "W m-2" ; 
DSR:coordinates = "Lon Lat" ; 
DSR:ancillary_variables = "DQF" ; 
DSR:valid_range = 0.f, 1500.f ;
