I used Zappier to essentially take the local weather and send it to my evernote email address (which you just get by having evernote) so it would create an entry for me with the weather.

Vitamin D and mood was done manually for me. All of these were part of my Timeline notebook that focused on daily events.

I consider this "ephemeral" tracking because it's not data you can benefit from in a long term fashion. For example if my happiness ratio is up by 2 points if I take 5000 extra IU of vitamin D a day, it might not be true 10 years from now. Which makes any data you get useful for a short time, but then it's just noise. You can't leverage.

Since it's just data points you can't even claim there is an emotional connection to it. I do tend to be very light in terms of data though, perhaps you might like seeing things from 15 years ago.

I think I get what you mean now... IIUC you still think there's value for that (even for a not long-ish term) but not for the VERY long term (?)
