<p>Hi NCL users,<br>
</p>
<p>Say I have a station's lat and lon, I also have MODIS data. In order to find the nearest 9 pixels' index to this station, I could calculate distance between every pixel and the station, then find the nearest 9 pixels.<br>
</p>
<p>Is there any NCL function to find 9 pixels' index in a faster way?<br>
</p>
<p>Thank you very much.<br>
