Bonanza Creek LTER: Hourly Snow Pillow Measurements from 2007 to Present in the Caribou-Poker Creeks Research Watershed near Fairbanks, Alaska

The snow pillow records the hourly water content of the snowpack (snow water equivalent) at the CARSNOW site within the Caribou Poker Creeks Research Watershed during the winter months. It consists of two 1m square aluminium "pillows" filled with a propylene glycol/water solution attached via piping to a druck pressure transducer. The pressure on the pillow is converted to cm of water. A manometer tube is also attached for manaul readings and calibration.
