Hi, Mary
I meet with the problem of the 2-dimensional lon and lat.
dimensions:
time = UNLIMITED ; // (1872 currently)
j = 384 ;
i = 320 ;
bnds = 2 ;
vertices = 4 ;
variables:
double time(time) ;
time:bounds = "time_bnds" ;
time:units = "days since 0000-01-01 00:00:00" ;
time:calendar = "noleap" ;
time:axis = "T" ;
time:long_name = "time" ;
time:standard_name = "time" ;
double time_bnds(time, bnds) ;
int j(j) ;
j:units = "1" ;
j:long_name = "cell index along second dimension" ;
int i(i) ;
i:units = "1" ;
i:long_name = "cell index along first dimension" ;
float lat(j, i) ;
lat:standard_name = "latitude" ;
lat:long_name = "latitude coordinate" ;
lat:units = "degrees_north" ;
lat:bounds = "lat_vertices" ;
float lon(j, i) ;
lon:standard_name = "longitude" ;
lon:long_name = "longitude coordinate" ;
lon:units = "degrees_east" ;
lon:bounds = "lon_vertices" ;

I have seen your reply to someone's same problem. But in my script I need
to choose one certain area. For example I use this function evecv =
eofunc(sst_CW({lat|20.:70.},{lon|110.:260.},time|:),1,False). So I want the
regular lon and lat. Do u know how to solve this. Attached is my script
about how to calculate the PDO. Thanks!

Best,
Ke Deng
