Add 'µmoles per m2 per second' as an alternative label to microeinstein per square meter per second?

[kristenpeach]

Hello! I work at NASA's GeneLab ingesting plant spaceflight studies into out repository. I use UO all the time and I appreciate the effort you've put into it! I'm having some trouble finding appropriate units to describe light intensity in plant growth studies. The most common unit I see used to report light intensity is µmol/m2/s, which I don't see a defined class for in Ontobee/BioPortal. I see you have microeinstein per square meter per second, which I understand is equivalent. However, the Einstein is not a unit in the SI (International System) of units, so for our repository using moles is preferred.

Would you be willing to make µmoles per m2 per second a synonym or alternative label to microeinstein per square meter per second?

Alternatively, does this already exist somewhere and I am just not seeing it?

Thank you for your help! Kristen

Friendly reminder to @reality we planned to add 'micromole per square meter per second' as an alternative label to 'microeinstein per square meter per second' when you have time :)
