Re: interpolate pixel level data into regular grid

x refer to time. This is hourly biomass emission data from 18:00-23:00 on 3/17/2012. What I want to do is to interpolate this pixel level data to regular grid (12km x 12km), but don't know which function can be used. Any suggestions are very appreciated!

The issue is "What does the named dimension 'x' refer to?"
There is nothing on the file to indicate its purpose.
You must find out before proceding.

Attached is a simple NCL script that plots the data.

netcdf biomass_burning_20120317_18_23 {
dimensions:
         x = 6 ;
         y = 371 ;
variables:
         float Latitude(y) ;
                 Latitude:long_name = "Latitude" ;
                 Latitude:units = "degree" ;
                 Latitude:valid_range = -90.f, 90.f ;
                 Latitude:scale_factor = 1.f ;
                 Latitude:add_offset = 0.f ;
                 Latitude:_FillValue = -9.f ;
         float Longitude(y) ;
                 Longitude:long_name = "Longitude" ;
                 Longitude:units = "degree" ;
                 Longitude:valid_range = -180.f, 180.f ;
                 Longitude:scale_factor = 1.f ;
                 Longitude:add_offset = 0.f ;
                 Longitude:_FillValue = -9.f ;
         float Burned_area(y, x) ;

Do I need convert lat/lon from 1D to 2D, and then do interpolation in this case? I am attaching the file. Any suggestions and help are very appreciated!
