FYI @ypwang19 is now on maternity leave, so I'll have to pick up this PR to get it finished, so there may be some delay in responses to reviews.

@aerorahul @DavidHuber-NOAA @WalterKolczynski-NOAA Yaping is now on maternity leave. What do you suggest in terms of getting this PR over the finish line? My suggestions in no particular order are:

• Merge as is (it's possible everything is fine, may need to stage some obs)
• Merge this except the task definition stuff so that nothing breaks
• Close the PR and I open a new one in my fork so I can make necessary edits
• Other options?
