A view of the
lower end of the mast looking up the south side of the mast shows the
system's Campbell Scientific™ CR10x dataloggers (two) enclosure (white
cabinet) located at 9.5' (2.9m) above the ground; a separate multiplexer
enclosure is located just below the dataloggers, out of view. On the arm
extending due south from the mast are mounted an ultrasonic snow depth
sensor (Campbell Scientific™ SR50), two down-looking pyranometers measuring
reflected radiation from the snow surface (a Kipp & Zonen CM21, 305-2800 nm
(50% points) and a Kipp & Zonen™ CM21 with RG695 filter dome, 780-2800 nm
(50% points)) and
an infra-red snow surface temperature sensor (AlpuG
GmbH™ SnowSurf).
Another arm extending east and west from the mast houses, to the
east, an air temperature and humidity sensor (Campbell Scientific™ CS500)
and, to the west, a second wind monitor (RM Young™ Model 05103-5).
