Program Goals

ARTMIP will benefit the atmospheric river scientific community, most directly weather and climate modelers. A catalogue of ARs and AR-related information will enable researchers to assess which identification methods are most appropriate for the science question being asked, or region of interest. Guidance on identifying ARs will provide for a set of best practices and community standards that researchers can work with and use to develop diagnostic and evaluation metrics for models and observational products.

Goal 1

• Provide a framework that allows for a systematic comparison of how different AR identification methods affect the climatological, hydrological, and extreme impacts attributed to ARs.

Goal 2

• Understand and quantify the differences and uncertainties in the climatological characteristics of ARs, as a result of different AR identification methods.

Goal 3

• Better understand changes in future ARs and AR-related impacts.
