There are two approaches here.


First:


x&lat = where(lat.gt.180,lat+360,lat)
x = lonFlip(x)




Secondly, you could perform a similar operation manually:


lat_new = x&lat
lat_new(0:180) = x&lat(181:361)
lat_new(181:361) = x&lat(0:180)


and code a similar shift/switch for the data in variable 'x' itself. This would be a bit extra work, considering the first method should result in the exact same result.


Hope this helps.

Hello all,

I have a data file in which the lon layout like: 0, ..., 180, -179, ..., -1.

How can I change the order of lon to: -179, ..., 0, ..., 180?

Thank you in advance for your help!
