Data Inter-Comparability from Different Instrument, Network Layers: Urban Canyons

Problem:
In many measurement problems, there are trade-offs between accuracy, precision, spatial measurement density (granularity), capital and operating costs. An optimal measurement network design may include:

• reference standard instruments (high accuracy),
• a medium quality instrument with a high level of precision (to provide spatial coverage) and
• a lower cost instrument to provide very high spatial density measurement ( to assess properties such as gradients or root causes).

To confidently assure the data quality, understanding the inter-comparability of these instrument layers over extended periods is critical.
