Objective:
Progress Summary:
1. Work status:
The UH-Atmospheric Radiation tower facility in A 2-year database of surface UV radiation measurements, atmospheric composition, meteorological data, and sky condition has been compiled and has been used to examine the relative importance of aerosols, clouds, and ozone on surface UV levels and ozone photochemistry in
2. Work progress:
There were two large data gaps during 2008-09 data sampling period, one in the UV-B monitoring instrumentation and the other in the CIMEL sunphotometer. The UV-B monitoring instrumentation was damaged during Hurricane Ike when 90+ mile per hour winds on the roof of
The UH CIMEL sunphotometer was sent back to NASA GSFC for its’ annual calibration in early May, unfortunately most of the AERONET team was away on an extended field campaign in
Future Activities:
We hope this research will provide data that are useful to the air quality forecast community whose models currently do not have adequate cloud and tropospheric pollution feedbacks. In addition, we will compare our results to future campaigns in 2009-10 in
