On Oct 10th, a small group of us went to the Heshan air monitoring supersite, to setup air sampling machines on the rooftop of the station building. This denotes that the field sampling campaign is on action, of which the objectives are to monitor and estimate the emissions of various pollutants (POM, POPs) and CO₂ etc from the PRD city cluster, by means of down-wind observations and modeling. The name of the campaign, Wind-in-his-air (风中散发-Emission in the wind), is adapted from the name of an Indigenous Indian in the Oscar Academy-winning movie ‘Dances with Wolves’ (与狼共舞）. The campaign is led by Shizhen, joined by Li Jing (modelling), Yao Chuxin (POM), Li Pingyang (CO₂), and many of the Air-Omics squad members. Occasionally, the wind field shifted to NNE from SE on the day, which is a sign of success.

Near-ground NNE wind started right on the day.

On August 10-11, Xiaofei, Shizhen, Li Jun and Zhang Gan joined with a group from SYSU led by professor Chen Jianyao (陈建耀）to visit Heyuan Hydrology Station (河源水文站）. This denotes a kick-off of our Dongjiang （东江） campaign dedicated to the NSFC Major Program ‘Geochemical Behaviours and Environmental Effect of Black Carbon (BC) Substances ‘ (The GeoBBC). By taking Dongjiang catchment as the research venue, we are hoping to illustrate a ‘regional’ picture of BC from the river source and the Pearl River estuary.

The visit, kindly arranged by Professor Chen, came out to be very successful, owing to his and SYSU’s strong influence on the Guangdong Hydrology Centre (广东省水文中心）and its branch Huizhou Centre (惠州分中心）to which the Station is affiliated. We had extensive discussions with the key staffs of Heyuan Station headed by Mr Tian Zhaowei (田兆伟）. Zhaowei and two of his colleagues Ms Chen and Ms Zhang Di are very professional, knowing Dongjiang in great details. Zhang Di, who obtained her MSc with Professor Chen in SYSU, introduced to us the whole picture of the hydrology stations across the Heyuan Section of Dongjiang. It seems that our Dongjiang campaign of the GeoBBC Program could be carried out as planned, with the expected strong support from Mr Tian and his teem.

After the official visit to Heyuan Station, our team was guided by Zhaowei to visit the Xinfengjiang Reservoir and had opportunity to discuss more with professionals there. We were also able to see inside the dam of the XFJ Hydroelectric Power Plant, and the beautiful scenery of the reservoir which is the second largest in China!

In the evening, Mr Zhou who is the head of the Huizhou Branch Centre of Guangdong Hydrology Centre joined us to ascertain kindly his strong support to our GeoBBC-Dongjiang Campaign.
