UK AERIUS Pilot Tool

Invitation to tender: Reference C20-0443-1521

JNCC is undertaking a project to implement a UK version of the Dutch AERIUS tool; the project is called ITAPA – Integrating Tools for Air Pollution Assessment. This builds on previous work to determine whether there is a case for further developing AERIUS for the UK. The aim of this contract is to deliver a pilot UK AERIUS tool to be able to test with stakeholders and validate against existing UK tools and approaches.

Specifically, JNCC is seeking:

  • Technical advice to support adaptation and validation of the AERIUS tool for UK implementation.
  • Project management, software development, tool build and demonstration of the pilot tool:
    • Adaptation of AERIUS tool available on Git Lab
      • Containerise the application for use in a cloud-based environment
      • Employ Nexus ( to further improve code-sharing and less dependable development throughout the project.
    • Include a UK appropriate dispersion model that will be agreed in a separate contracted piece of work;
    • Inclusion of UK-specific data (e.g. emission factors, habitat maps, protected areas, concentration/deposition) compiled in a separate contract;
    • Hosted on an agreed environment.
  • Handover and documentation for taking the pilot tool forward into testing and validation phases:
    • UK AERIUS data flows and process structure diagram advice and assistance with design; and
    • UK AERIUS user manual.
  • Advice on further phases of the project subject to funding (e.g. AERIUS Register adaptation for UK)
