Re: [ferret_users] [Ferret_Users] sampling lon and lat

[Steve Hankin <steven.c.hankin@xxxxxxxx>]

Hi Vinu,

Depending upon the character of your data (i.e. the path of the corresponding contour line) and the manner in which you want to use the results there are two functions that may deliver something similar to what you are after:

• @loc -- ("location of") can find the lats and longs for fields that hit the contour line value just once
• @evn - ("event") more complex, but can be used if the field hits the same value multiple times

Hi all,

	Is there any way to sample the longitude
and latitude points through which a particular contour line passes?


I want to sample the longitude and latitude of the
zero_contour line of a variable.

Thanks in advance
