Description

Latitude:

-8.9615045445

Longitude:

-77.6322786459

Altitude:

4797.0 m a.s.l.

This station was installed in the framework of the FWF project P 16113 in March 2004 on the glacier Artesonraju in the Cordelliera Blanca in Peru at an altitude of 4797 m a.s.l. to investigate the glacier climate interaction. The station operated until May 2013 and was visited (and moved) several times by the team around project leader Georg Kaser (ACINN, former Innsbruck Tropical Glaciology Group at the Institute of Geographie).

Station History

• 09.03.2004: station installed on glacier surface in March 2004 at "approximately" the current position - close to the IRD AWS
• position was changed several times
• 11.2004: station moved close to the glacier terminus, subsequently every year a bit away from the terminus to prevent it crashing, and in 2009 to the current position (Hector Oropeza and Jesus Gomez)
• 07/2010: major changes - CNR1 sensor replaced by CNR4; Judd replaced by Cambell SR50
• 06/2011: pressure sensor installed - data questionable
• May 2013: last data download from members of the group.
