COMMENT ON THE SITE
●Additional observation programs:
(a) GCOS Upper Air Network (GUAN): upper-air observation (b) GCOS Surface Network (GSN): surface observation
(c) WMO-GAW programme: ozone observation by the Brewer spectrophotometer AOD observation by PFR sunphotometer
atmospheric background pollution observation
(i.e. CO2, CH4, CO and surface O3density observation,
chemical component observation of precipitation and settled dust)
●Calibration:
All di lib d 5 A h li d
All radiometers are calibrated every 5 years. A pyrheliometers and pyranometers are
traceable to the WRR, and a pyrgeometer is traceable to the World Infrared Standard Group (WISG). The tracker will be overhauled every 5 years by its manufacturer.
