Methods and protocols used in the collection of this data package
Description:

Experimental Design

Starting in 2020, many of the successional replicate climate stations were retired from service and those data streams will terminate.

Methods

Recorded hourly on CR10x-PB dataloggers using SR50 ultrasonc snow depth sensors. Original Data were collected with Campbell Scientific 21X dataloggers. LTER1 uses a Ultrasonic snow depth sensor UDG01.(no longer available for sale). LTER2 used the SR50 ultrasonic snow depth sensor. Field sensitivity of sensors was 0-10 cm.
