Get a region from a larger data

[J Conrado]

Hi,


I have GOES16 full disk data with the dimensions (5424, 5424) and my 
latitude and longitude arrays have the same dimension.

How can I seletct a small  region of this data, using  this limits for 
lat=[-30,10] and lon = [-90,-30] for my sector. I try to select my 
region using this limits.

But, I didn't have success.


Tanks,


Conrado
