JH, 

have you already tried to display smothed variables? 
Maybe: 
'd smth9(smth9(smth9(var)))' 
or a more smothed display could sove the problem.

> StationID Longitude Latitude JulianDay
> 100 36.573 128.707 249
> 121 35.105 129.032 262
> 122 36.573 128.040 265

> As you can see station 121 and station 122 are near to each other,

> By making the JulianDay 249 as the min. shaded level and JulianDay
> 265 as the max. shaded level. It gives me a non-interpolating area.
