Typical visibility In Shanghai Typical visibility In Boulder
Scientific objectives (1) Establish an effective measurement network to study ozone and ozone precursors, and use the measured result to evaluate WRF-Chem calculations. (2) Study whether the ozone formation is NOx inhibited or VOC limited in the city. How strong is the VOC-limitation to ozone formation in different locations in the Shanghai region? (3) Understand the impacts of different anthropogenic activities (e.g., traffic, chemical industry) on ozone formation in this region.
(4) Study the impact of high aerosol loading on photochemistry. How strong is the photon-limitation to ozone formation in different locations in the Shanghai region? (5) Understand the effect of biogenic emission on ozone concentrations in Shanghai and the surrounding region. How do biogenic emissions interact with anthropogenic emissions to form ozone ? (6) Assess the interactions between the city and surrounding area for ozone formation. (7) Establish a chemical weather forecast system (CWFS) to forecast O 3 and visibility and to assess the impact of the rapid economical development on the future air quality in YRD

The experiment duration The experiment will take place from Sept/1/2009 to Sept/21/2009. The second Phase of the experiment The experiment will take place fin spring (NW winds), May/2012???
Participants from NCAR Guy Brasseur (ESSL Director), a few day trip in SMB to oversee the experiment Bill Randel (ACD director), oversee the experiment Sasha Madronich, oversee the experiment Xuexi Tie, Coordinator between NCAR and SMB, and WRF-Chem modeling Alex Guenther, Jim Greenberg and Andrew Turnipseed: VOC fluxes at DT and XJH Sites and VOC measurements at XJH, CM, BS and SS sites Eric Apel+1 VOC measurement at JS site Frank Flocke + 1 NO, NO2, NOx, NOy, O3 measurements and inter-comparison at XJH Bob Henson – UCAR P-R (1 week) Total = 12 (3 for short period, and 9 for 4 weeks)
NCAR cost Airline tickets; 10 x $1500 = $15K Shipment cost; 3 x $9000 = $ 27,000 Materials and Supplies (e.g., GC gases, standards, cartridges): $8K Mis cost 5K Estimated total cost by NCAR ~$55K x 1.5 (over-head) = 82.5K
SMB matching cost; Hotel cost: 30 day x $80 x 13 people = $31,200 Per diem cost (food + transportation) 30 day x $40 x 13 = $ 15,600 Some other cost; $15,000 Data management cost; $7,000 Enhancement Ozonesonde cost; $10,000 Estimated total matching cost by SMB; $78K - $80K Additional instrument purchase (J[NO2]) etc, $30K
Pre-campaign activities More WRF-tracer study, improve in emissions Intensive VOC measurements by SMB 1-week each in XJH, JS, and DT (diurnal cycle during daytime in May/2009?? Data analysis by ACD and SMB for 2005-2008 period
Pre-campaign Preparations Coordinate with other Institutes and Universities? (Xi-An; Texas AM; Peking University; Fudan University; CMA) Shipments of NCAR instruments? When and How? Preparations in the field sites (Hotels and transportations) Data managements, Web-site establishment
