[ferret_users] point selection & dimension removel



Hello,

 

I have the following problem:

I have a grid with land and ocean points. I want to pick out the land points and unravel them on a 1 dimensional vector. I have a land sea mask, and I can generate lats and lons as 2 dimensional fields, e.g. see the map of the latitudes below.

 

I know how many points overall on the grid and how many land points.

 

I can do an xsequence on the latitude field, but the results still contains the missing values from the ocean areas. Ideally, I would like just to forget about them.

I guess I could also do an reshape, but that would have the same problem, no?

 

Any suggestions most appreciated!

 

Thank you very much,

Cheers,

Joerg
