An intensive field campaign including measurements from the environmental monitoring network and from two super sites took place in the Pearl River Delta region in summer *** routinely measured O3 and NOx concentrations,the spatial and temporal variation of O3 and of the total oxidant concentrations was *** to the spatial variability of NO2/NO,the two super sites were found to be representative of polluted urban and downwind suburban *** addition,both sites were located in high O3 ***-depth diagnostic of photochemical ozone production processes and their key controlling factors are achieved with an observation-based model(OBM) to gain regional *** analysis and sensitivity model runs show that aldehyde and HONO chemistry had significant impacts on local photochemical ozone production *** analysis of calculated Relative Incremental Reactivities shows that photochemical ozone production rates are mainly sensitive to anthropogenic hydrocarbons(HCs) in the polluted urban *** the suburban areas,sensitivity to nitrogen oxide(NO) concentrations *** anthropogenic HCs in both areas are alkenes and *** differences of ozone production efficiencies are identified between the urban and suburban regions,consistent with the OBM diagnosed results.

Co-Seismic Focal Mechanism of 1999 Chi-Chi Earthquake(1999, Taiwan, Mw 7.6) Deduced from Gouge Magnetic Fabric

It is known that the gouge fabric can provide the elements of the focal mechanism of an ancient earthquake. However, the comparison between the gouge fabric and the focal mechanism of a modern earthquake remains to be established. Here, we present magnetic fabric investigation of gouges and wall rocks of the Chelungpu fault, where Chi-Chi earthquake took place(1999, Mw 7.6). Rocks are obtained from fresh surface outcrop and 1 km deep borehole(Hole B, Taiwan Chelungpu-fault Drilling Project). Deep gouge hosts the 3-mm thick principal slip zone of Chi-Chi earthquake, which is also analyzed. Wall rocks display contrasting magnetic fabric.
