(2)People in charge of the instruments 
Gaowei
(3)Descriptions of the instrument 
The EC9810B ozone (O3) analyzer is a nondispersive ultraviolet (UV)
photometer which alternately switches a selective ozone scrubber in and out of the
measuring stream and computes the ratio of transmitted light giving an accurate
and reliable measure of ozone concentration in the presence of common
atmospheric compounds. 
(4)Measurement accuracy and uncertainty 
Noise (RMS)
Measurement process: 0.25 ppb or 0.1% of concentration reading,whichever is greater; with Kalman filter active.
Lower Detectable Limit
Measurement process: Less than 0.5 ppb or 0.2% of concentration reading,whichever is greater; with Kalman filter active.
(5)Names of the measured species 
Surface Ozone 
(6)Units of the measured species 
PPB
(7)Measurement site 
Pudong
(8)Measurement date (from Mon/day/year to Mon/Day/year) 
From 08/30/2009 to 09/22/2009
