Meeting notes

Standard Names

• Reconsideration of “add four wind CF variables #73” (#77)
  • Old issue - related PR is merged
  • Michael K to close
• What to do if there are two identical quantities from different schemes that need to be kept apart (#79)
  • Cheryl has been using “due_to” on CAM-SIMA side of things
  • Grant likes Matus’s suggestion
  • Cheryl - when do we use “from” vs “due to”
    • Grant - “due to” is process and “from” is a piece of code (but that’s just an instinct)
  • Dom - not at levels where high altitude levels - overlap with other variable
  • Jesse - are they triggering off of the same quantity?
    • Dom - guess is that they’re triggering off of different mechanisms
    • Grant - Maybe be more specific about the processes in the name instead of differentiating between pieces of code (will replace the vague “nonorographic”)
    • Grant - should update rules to explain differentiating between processes
• Update rules to add _due_to_planetary_boundary_layer (vs. PBL?) (#80)
  • Dom - Will need to document the abbreviations we use in the rules
  • Michael K - use abbreviation and then spell out full name in the long name
• Modify skin temperature at surface variables (#84)
  • Michael K to ping Steve Vahl to change “sea” to “ocean”
• Add emissions names (#86)
  • Michael K offered some names to comply with our rules
  • PR author needs to modify XML
  • Dom - “emissions” vs “emission”?
  • Michael W - will this be a naming rabbit hole? Residential? Traffic? Etc?
    • Michael K - as long as they’re meaningful distinctions, seems ok
    • Michael K - will ask if they will eventually a need a solo “residential” and a solo “commercial” emissions stdname
  • Jesse - put emissions in its own section?

Discussion

• Workflow discussion
  • People should take a look at Michael K’s document and offer suggestions on what we want to change
  • Will try the existing workflow of develop -> main and see if it “works” for everyone
• UCAR SEA conference in April
  • Dom - would be nice to have someone present on framework stuff
  • Abstracts due in January
• Michael K opening PR soon with standard name rules stuff we’ve been discussing!
