APPEAR aims to bring together research exploiting perturbed parameter ensembles (PPEs) to understand and predict the behaviour of the atmosphere and climate system.

Registrations are open for the Analysis of PPEs in Atmospheric Research (APPEAR) virtual workshop to be held over 2 days: 18 October (15:00-19:00 UTC) and 19 October 2022 (08:00-11:00 UTC). The workshop is organised under the new WCRP Earth System Modelling and Observations (ESMO) Core Project and will showcase the wide range of PPE-related research across atmospheric science. The overall aims are to define the range of approaches and applications, to share expertise on how the many challenges of PPE creation and analysis are being tackled, to build a community of researchers, and to scope out the opportunities for further development and collaboration.
