Welcome to the TAPPAS Wiki where we encourage user collaboration, input and suggestions for the continual improvement of TAPPAS.
TAPPAS (Tool for Assessing Pest and Pathogen Aerial Spread) is an online software tool that was developed by CSIRO, the Australian Bureau of Meteorology (BOM) and Intersect to enable biosecurity managers and scientists to quickly and easily model the dispersal of living organisms. The application has been specifically developed in consultation with researchers, policy-makers and practitioners to help them address biosecurity questions. It will become an essential biosecurity tool for preparing and responding to wind-borne threats.
TAPPAS Version 1.0 already contains considerable functionality. However, we aim to continue development in partnership with collaborators and clients. User feedback and analysis of usage patterns will assist this process.
TAPPAS Version 1.0 is undergoing a staged release as we continue testing. Initially it is available for users to explore its potential for biosecurity, health and other fields. Please contact us if you are interested in working with us to further develop and apply TAPPAS.
This wiki provides an overview of TAPPAS and its application to investigating biosecurity questions related to dispersal, as well as details and a basic tutorial on its use. It can also be used as a help manual for TAPPAS. We encourage users to provide constructive feedback on the content.
§Why use TAPPAS?
The underlying TAPPAS architecture is intentionally very flexible. It can therefore be applied to a wide range of other fields, such as biogeography and allergen risk analysis. Please contact us if you would like to explore possibilities.
Of interest to biosecurity is the likelihood of successful wind dispersal occurring between a source and a destination. TAPPAS allows modelling of the movement and deposition of organisms in the wind column. Future versions will also allow consideration of survival in the wind column, and more explicit consideration of likelihood of uplift and likelihood of establishment when deposited.
TAPPAS is a user-friendly interface that allows users to run sophisticated wind dispersal scenarios by linking a particle dispersion model (HYSPLIT) and meteorological data generated by Numerical Weather Prediction Models. TAPPAS models are run on a high-performance computer in Canberra, Australia.
Key features of TAPPAS include:
- Near real-time analysis: outputs can be generated in minutes or hours using the latest climate data
- No requirement for expertise in modelling, GIS or IT
- Ability to incorporate biology of the organism into simulations
- Ability to assess the risk of movement of widely distributed organisms (diffuse sources)
- Ability to assess the risk of dispersal on both specific dates (e.g. incursion events) and time periods (e.g. season)
- Visualisation of results as risk-maps
- Results are able to be downloaded
- A flexible software architecture which means that other dispersion models and atmospheric circulation models can be added, and the interface modified for specific applications.
