I believe this new version does not produce the PIO_IOTYPE_PNETCDF warning. However, I am just checking to see if this is correct.

The oxid year (2015) and linoz year (2010) are now inconsistent. Consider documenting why different years are used for these related chemistry datasets or using the same year for consistency.

We don't have year 2010 for oxid, so use year 2015 instead.

I see a different date, 20250813, for these files. In the Linoz files, we have 20250826. I am just checking if we have fixed the PIO_IOTYPE_PNETCDF warning in these files.
