<p>Respected Mary,</p>

<p>Thank you very much. I tried to many files using "cat" option. I got error like "File too large: error attempting to write variable (pr) to file (pr_day_CMCC-CM_rcp45_r1i1p1_20060101-20351231.nc)". It seems that there is a limitation on a number of files
and files sizes. Is there any way to solve this problem? Thank you very much for your time.</p>

Respected all,<br>
<br>
Is the warning " warning:error attempting to fix non-monotonic aggregation variable" while joining files makes any differences? The first file has dimension size: 366x240X480 and second file have 365x240x480 or first-year data is leap year data. Even with
using both non-leap year data, I found the similar problem. What is the reason for getting this problem and how can I solve it?<br>
