Scenario Modeling Tool for Air Pollutant Emissions

Tender description

The Authority requires robust, agile and repeatable analysis of future air pollutant emissions and concentrations to underpin Air Quality policy development. Currently we have a range of tools and datasets that were built for a range of different purposes. Enabling them to work together is often a time consuming and laborious task that requires expert interpretation and manipulation leading to inefficiencies. Therefore, the authority seeks a tool that will make best use of current data sources, such as the NAEI, and enable the user to interact with the datasets in the following ways: altering activity levels and emission factors to produce new scenarios at a range of scales from site level to national; setting parameters for estimation of variability and uncertainty; and choosing the geographic scale of emissions outputs ranging from national down to local and the spatial scale (1km2 grid squares at a minimum but preferably to finer geographic scale). In doing so the tool will enable the exploration of data in a transparent and reproducible way that can form a consistent approach to deriving emissions datasets for model to explore future scenarios, eliminating key uncertainties in deriving appropriate datasets. The tool should look to enable the interrogation and manipulation of data at different levels of need to facilitate the needs of basic and expert users in a coherent and consistent manner.
