This project aims to develop and assess a comprehensive, fully-automated, space weather forecasting capability for the coming decade. We will develop a highly-efficient forecasting model for ambient solar wind and coronal mass ejections (CME), based on novel boundary conditions near the Sun. The model will forecast solar wind/CME speeds and densities throughout the inner solar system, at a fraction of the computational cost of even the most efficient current operational models. Another novel aspect is the use of boundary conditions gained from coronagraph image observations near the Sun. The ambient solar wind boundary is driven by tomographical maps of the coronal density (see https://solarphysics.aber.ac.uk/Archives/tomography/), building on the CorTom module of the operational SWEEP package (SWIMMR S4 project), and recent published work by Kaine Bunting & Huw Morgan. The CMEs are injected into the model based on the results of the ACME-3D software, recently developed in Aberystwyth (see https://solarphysics.aber.ac.uk/Archives/cme_realtime/, publication pending). A comprehensive assessment of the system's performance will be made on a large set of historical data.

该项目旨在开发和评估未来十年的全面，完全自动化的太空天气预测能力。我们将基于太阳附近的新边界条件，为环境太阳风和冠状质量弹出（CME）开发高效的预测模型。该模型将以最有效的当前操作模型的计算成本的一小部分预测整个太阳系的太阳风/CME速度和密度。另一个新颖的方面是使用从太阳附近的冠状图像观测中获得的边界条件。环境太阳风边界是由冠状密度的层压图驱动的（请参阅https://solarphysics.aber.ac.ac.uk/archives/tomography/），在操作扫描软件包的皮层模块（游泳MR S4 Project），Project ot以及Kaine Bunting＆Huw Morgan最近发表的作品。 CME根据最近在Aberystwyth开发的ACME-3D软件的结果将CME注入模型（请参阅https://solarphysics.aber.ab.ac.ac.uk/archives/archives/cme_realtime/，publication deckende）。对系统性能的全面评估将对大量的历史数据进行。
