Abstract:
To make space science and space weather models useful for application purposes, it is important to validate them using proper metrics. Working with the community, the Community Coordinated Modeling Center (CCMC) has initiated the International Forum for Space Weather Modeling Capability Assessment. The plasma and radiation effects group stemmed from this effort has discussed and come up with a set of science and engineering metrics for several types of effects that are relevant to spacecraft and/or other space assets (https://ccmc.gsfc.nasa.gov/assessment/topics/radiation-all.php). In this presentation, initial validation results of a few models in producing surface charging effect during two events/intervals (Event 1: from 16 March to 20 March 2013; Event 2: from 31 May to 2 June 2013) will be shown. The goal of such validation effort is to be able to track model performance over time and at the same time to provide feedback and stimulate improvement of models. The two events occurred during geomagnetic time periods where the former was due to a CME and the latter was likely caused by the flank impact of a slow CME followed by a high speed stream. Therefore, different solar drivers’ influence on the near-Earth region and on surface charging can be analyzed as well.
