title: Extracting the value from Netcdf file with longitude and latitude
body: <p>I would like to extract temperature values from model output with python. </p>
  
  <p>My model output have separate temperature, longitude and latitude variables. </p>
  
  <p>So, I overlap these three grid variables on one figure to show temperature with longitude and latitude through model domain. </p>
  
  <p>Up to this point, everything is fine. The problem is to extract temperature value at certain longitude and latitude. </p>
  
  <p>Temperature variable doesn't have coordinate, but only values with grid. </p>
  
  <p>Do you have idea about this issue? </p>
  
  <p>Here is my code for the 2 D plot with temperature on model domain:</p>
  
  <pre><code>varn1 = 'T2' 
  varn2 = 'XLONG' 
  varn3 = 'XLAT' 
  Temp  = read_netcdf(filin,varn1) 
  Lon  = read_netcdf(filin,varn2) 
  Lat  = read_netcdf(filin,varn3) 
  
  Temp_plt =  Temp[12,:,:] 
  Lon_plt = Lon[12,:,:] 
  Lat_plt = Lat[12,:,:] 
  x = Lon_plt 
  y = Lat_plt 
  </code></pre>
  
  <hr>
  
  <p>read_netcdf is a code for extracting values of [time, x,y] format. </p>
  
  <p>I think that the point is to bind x, y in Temp_plt with x, y in Lon_plt and Lat_plt to extract temperature values with longitude and latitude input.</p>
