California SNOTEL Site Summit Meadow (1052) - Hourly Sensors for
2025-April-24 NRCS National Water and Climate Center
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.
The label is constructed as follows: [Ecode.Function Interval-Ordinal:Sensor Height]
*The use of a particular manufacturer's instrument does not consitute an endorsement of that instrument or manufacturer.
