Also, I believe there is a Python binding for NCO: e.g.,

Indri,
Please keep the conversation on the mailing list by using CC or Reply All.
The attributes that you highlighted are simple text strings, which are easy to
change. This can be done on the unix command line with no programming, with
freeware packages such as NCO (NetCDF Operators). There are several examples
in the description of the ncatted utility (attribute editor) in the NCO
documentation:
http://nco.sourceforge.net/nco.html#ncatted-netCDF-Attribute-Editor<https://gcc02.safelinks.protection.outlook.com/?url=http%3A%2F%2Fnco.sourceforge.net%2Fnco.html%23ncatted-netCDF-Attribute-Editor&data=04%7C01%7Cchristopher.s.lynnes%40nasa.gov%7C729cfc043d354973d16c08d8c3313910%7C7005d45845be48ae8140d43da96dd17b%7C0%7C0%7C637473963470447657%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=XZnYIDD8L6ggVxC7eeTJkNDXnUoBAc5Wi1%2BVd6l1Xlk%3D&reserved=0>
Here is an example that might work on your actual data file:
ncatted -h -a START_DATE,global,o,c,'2099-01-01_18:00:00' \
-a SIMULATION_START_DATE,global,o,c,'2099-01-01_18:00:00'

I am sure there is also an easy way to do this in python. Perhaps one of the
python programmers here can give an example.

Hi Dave,
Thank you for answering my question,
what I'm going to edit is to change the attributes of ncfile, for example :
[cid:image001.png@01D6F552.D068C9A0]
In this ncdef file, I want to change start date and simulation start date. Is
that possible?
And my language programming is python.
I am really grateful for your help for answering my questions associated on my
research.
Thank you in advance.
sincerely
Indri

Indri, there is more than one way to store date and time in a netcdf file.
Please show an actual short example, and describe the general nature of how you
want to change it. Also, what programming languages do you like to use for
data work?
