Climate data for Green Lake 4 data loggers (CR10-CR1000), 1997 - 2019.

Climatological data were collected from a Niwot Ridge climate station (GL4) throughout the year using a Campbell Instruments CR10 data logger (1997-2013), a CR1000 data logger (2013-2017), and a CR850 data logger (2017-2019). Maximum and minimum values are recorded instantaneously, with the sampling interval being 10 seconds. Daily averages and totals were calculated from 8,640 individual measurements. This instrument was programmed to generate both hourly and daily output.
