MATLAB: How to set Time Axis

Question

Hi Folks

I have a data in which time axis set in following format

       ncdisp('myfile.nc')
       time              
           Size:       39x1
           Dimensions: time
           Datatype:   single
           Attributes:
                       standard_name = 'time'
                       long_name     = 'time'
                       units         = 'months since 1970-01-01 00:00:00'
                       axis          = 'T'
                       climatology   = 'climatology_bounds'
      year=ncread('myfile.nc','time')
      year=
    9×1 single column vector
     6
    18
    30
    42
    54
    66
    78
    90
   102
   114
   126
   138
   150
   162
   174
   186
   198
   210
   222
   234
   246
   258
   270
   282
   294
   306
   318
   330
   342
   354
   366
   378
   390
   402
   414
   426
   438
   450
   462

But i want to convert variable year(6,18,30,…,462) to year(1:39), which represent 1 as 1970 and 39 as 2008;

I mean

year(1)=1970
year(2)=1971 
.
.
.
year(39)=2008

Could you please suggest me, how can I make it ?

Thanks in advance

Answer 1

ncmon = ncread('myfile.nc','time');
year = 1970 + floor((ncmon - 1) / 12);
