Site visit report - Cherskiy 2013


Repairs, calibrations and upgrades were made during late August at the Pleistocene Park tall tower near Cherskiy, Russia.  An automated CO2 height profile measurement system was installed to help assess the role of periodic CO2 storage in daily or hourly flux estimates.  During periods of low wind, such as commonly occur during night-time, turbulent mixing of CO2 can be reduced such that levels near the ground may differ from the concentration observed at the eddy covariance measurement height.   Our system will measure 5 different heights from 2m to 35m along the tower several times per hour.  This year looks to be the best yet in term of getting continuous high-quality flux measurements from this site, thanks to the efforts of our Russian colleagues.

Imnavait Creek spring activities


An unusually late, cold spring has delayed snow melt in northern Alaska.  Our site visit this year included re-installing the methane sensor, calibrating and repairing analyzers and communications equipment, all in winter-like conditions despite it being late May.  This will be the second summer of continuous CH4 flux measurement at the Fen moist-acidic tundra site.  The instrument was set up well ahead of the melt, so we hope to get some exciting data.  Our webcams are all online now, and images are still being harvested by the PhenoCam network.

Phenology Webcams join PhenoCam Network


Images from our four webcams at Imnavait Creek join the PhenoCam network.  This is an effort to improve understanding of vegetation phenology via a network of canopy cameras.  Images from our phenology webcams begin in June 2012 and can now be found in the 'Affiliated sites' section of the PhenoCam website:
