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、全自动空间气象预报能力。我们将根据太阳附近的新边界条件，开发一个高效的环境太阳风和日冕物质抛射（CME）预测模型。该模型将预测整个内太阳系的太阳风/CME速度和密度，即使是目前最有效的运行模型的计算成本也只有一小部分。另一个新颖的方面是使用从太阳附近的日冕图像观测获得的边界条件。环境太阳风边界是由日冕密度的断层摄影图驱动的（见https：//solarphysics.aber.ac.uk/Archives/tomography/），建立在SWEEP操作包（SWIMMR S4项目）的CorTom模块上，以及Kaine Bunting和Huw Morgan最近发表的工作。根据最近在阿伯里斯特威斯开发的ACME-3D软件的结果，将CME注入模型中（见https：//solarphysics.aber.ac.uk/Archives/cme_realtime/，待出版）。将根据大量历史数据对系统的性能进行全面评估。
