An updated version of the H-K Table was published today. Version 1.2 corrects time variables that were present in the Version 1.1 pdf but not the json files; adds a variable for upward_air_velocity; tweaks attributes for a few existing variables (see the Lineage section for details); and adds license and citation information. Many of these changes came about due to discussions associated with last week's hands-on workshop in Stockholm; thanks to all who helped in this fashion!
Version 1.2 would be specifically cited as
Hartten, Leslie M., & Khalsa, Siri Jodha S. (2022). The H-K Variable SchemaTable developed for the YOPPsiteMIP (1.2). Zenodo. https://doi.org/10.5281/zenodo.6463464
However, you can more generically cite all versions by using the DOI 10.5281/zenodo.6255666 ; it represents all versions, and will always resolve to the latest one.
