[ncl-talk] query ( CONVERSION ASCII TO NetCDF)

[Yuqiang Zhang]

Hi Kunal,

 

In line 30, “ncl 30> TotCH4_A = data(:,2) “. You variable “TotCH4_A” is only assigned one dimension’s value, so you can’t assign two dimension through line 33 & 34. 

 

Regards,

Yuqiang

Dear NCL user 

I tried this script from NCL but still getting error 


ncl 28> Longitude = data(:,1)
ncl 29> Latitude = data(:,0)  
ncl 30> TotCH4_A = data(:,2)  
ncl 31> ncdf = addfile("/home/kunal/simple1.nc","c")
ncl 32> filedimdef(ncdf,"time",-1,True)              
ncl 33> TotCH4_A!0 = "Latitude"
ncl 34> TotCH4_A!1 = "Longitude"
fatal:Variable (TotCH4_A) has (1) dimensions can not write to dimension (1)
fatal:["Execute.c":8565]:Execute: Error occurred at or near line 34

Hi Kunal,

 

Please, take a look at the 'output netcdf' examples page, method_1

 

http://ncl.ucar.edu/Applications/method_1.shtml

Try this:

 

 

lat = data(:,0)

lat = data(:,1)

values= data(:,2)

 <http://ncl.ucar.edu/Document/Functions/Built-in/system.shtml> system("/bin/rm -f simple.nc") ; remove any pre-existing file 

ncdf = addfile("simple.nc" ,"c") ; output netCDF file
 <http://ncl.ucar.edu/Document/Functions/Built-in/filedimdef.shtml> filedimdef(ncdf,"time",-1,True) ; recommended
values!0 = "lat"
values!1 = "lon"
values&lat = lat
values&lon = lon 
ncdf->values = values

 

Bye, Karin

Dear NCL users

I want to convert ASCII to .nc file format. Could any one please provides me the link for this query or give any detail about this ??

I have data in 3 column ( Latitude Longitude Values)

More Detail

Variable: data
Type: float
Total Size: 777600 bytes
