Daily sensors report a summary value for the previous day.
Hourly sensors report a summary value for the previous hour.
Instantaneous sensors report a single observation on the hour.
Instantaneous sensors are included with both Daily and Hourly sensor selections.
Instantaneous sensors for a Daily sensor selections are the midnight observation.
