Methods:
The Garwood Ice Cliff meteorological station was added to the McMurdo Dry Valley
network in the 2012-13 field season.
GAFM transfer process will be finsihed off this year
The GAFM station was moved ~5 m from its original site in 2013 (out of the stream bed). At this time, the three 107 temperature probes were placed in a vertical profile (10, 5, and 0 cm), similar to the other AWS (recording in Celsius)
Air temp and RH are at 3 m, along with wind direction and speed. Incoming and outgoing SW and LW are also at 3 m, but were oriented parallel to the ground surface (rather than normal) in order to capture radiative flux into/out of the ice cliff. In 2013-2014, these sensors were replaced with a single NR-LITE2 net rad sensor which is oriented in a typical, ground-normal orientation (the original sensors did not survive contact with a katabatic wind storm some time over the winter). The SR is also at 3m and points towards the ice cliff. This instrument died in 2013 and failed in 2013-2014. I've got a replacement we can install this field season, since it is a useful measurement.
The station was set up to sample sensors every 30 seconds and send summary statistics (for example, averages and
maximums) to solid-state storage modules every 15 minutes. This has resulted in approximately
20 values being recorded for final storage in every output interval.
