At the top of the
SBSP mast are deployed a wind monitor (RM Young™ Model 05103-5), two
up-looking, full-range pyranometers (Kipp & Zonen CM21, 305-2800 nm (50%
points)), a third filtered pyranometer (Kipp & Zonen™ CM21 with
RG695 filter dome, 780-2800 nm (50% points)), and a pyrgeometer (Kipp &
Zonen™ CG4). One of the full-range up-looking pyranometers is deployed
with a fixed shadow band for measurements of diffuse radiation at solar noon.
The shadow post is modeled upon the Swiss's Alpine Surface Radiation Budget
project specifications. Air temperature and humidity are monitored just below the level of the radiation sensors (Campbell Scientific™ CS500).
