Aloha Grads Users, <br><br>I have hourly rainfall data over the island of Oahu that is spread amongst 20 or so stations. I would like to do some kind of objective analysis on the data in order to make a rainfall contour map. I found this function: <code>oacres (<i>gexpr, sexpr <,radii></i>) </code>which seems promising. I'm not sure what to do about the station data though because I've never dealt with it before. If I output it in grads binary format, should I just fill in undefined values for all grid points except where the stations are? Do I need full station data such as winds and pressure (I don't have that, just rainfall)? If I output the rainfall data as a variable called "rain", would I type:'d oacres(rain,rain)' ? <br>
