| Location | Mt. McKinley, Denali National Park, Alaska (just above Denali Pass) (63º 04.773’N 151º 01.769’W 5715m) | |||
| Description | This is a small, high altitude weather station. The
purpose is to collect meteorological data on the mountain and transmit
it to the Visitor Center for real time data display. Real time data
helps with weather forecasting and is of vital importance to those
planning mountaineering attempts on Mt. McKinley (Denali). It is also
interesting to
the general public. On-line slide show of the installation expedition http://www.iarc.uaf.edu/gallery/main.php?g2_view=core.ShowItem&g2_itemId=1427 The datalogger is powered using Lithium batteries from Saft (model #LSH20). Lithium batteries work to -40 C with a 40% capacity derating. Battery datasheet  http://www.septechnologies.biz/battery/products/manufactures/saft/spec_sheet/LSH_20.pdf |

| Data | Wind speeds, temperature, and barometric pressure are
measured using an
Vaisala ultrasonic anemometer, a cup anemometer, two thermometers, and
a
pressure sensor. Project Website with real-time data: http://www.iarc.uaf.edu/mt_mckinley/index.php |

| Comms | Data is stored using Campbell Scientific CR1000 datalogger and transferred via a Polartronix PX-503 VHF telemetry system with relay stations. |
