spatial representativity - Report of 2013 WG2/SG1 activity

The assessment of spatial representativeness of air quality monitoring stations is an outstanding issue that impinges on several areas relevant to risk assessment and population exposure as well as on the design of monitoring networks, model development, evaluation and data assimilation. There are several approaches proposed in the literature that try to define the area of representativeness of a monitoring station as “a similar area” or “spatial homogeneous field of pollution” (e.g. Bobbia et al., 2008). Such a definition cannot fit the intrinsic anisotropy of the atmospheric flow and dispersion, and is limited in time.JRC.H.2-Air and Climat
