As the core of the national administration, the resolutions of the Executive Yuan Session are the basis for the subsequent actions of other executive authorities at all levels, and the relevant written records not only serve as the basis for the overall administration of the country, but are also important for the continuous development of the records of the past sessions, which are a reflection of the trajectory of the national development. In view of this, this study focuses on the Executive Yuan Session's Minutes of the National Government (...), and explores the functions, rules, and roles of Executive Yuan Session and the contents, structure, and characteristics of Executive Yuan Session's Minutes through documentary crawling and collation. This paper also discusses the editions, current conditions, and value of the Executive Yuan Session's Minutes held by National Archives Administration, National Development Council (NAA), and serves as a reference for the relevant institutions and subsequent research.

Atmospheric transport and dispersion models (ATDMs) are widely used to study and forecast pollution events. In the frame of the "Effect of Megacities on the transport and transformation of pollutants on the regional to global scales" (EMeRGe) project, ATDM forecasts were carried out to identify potential airborne sampling areas of perfluorocarbons (PFCs) emanating from controlled PFC releases. The forecasts involved short-distance transport over small-scale topographic maxima (Manilla; Philippines), short-distance transport over large-scale topographic maxima (Taipei, Taiwan) and long-distance transport over mixed topography (Nanjing, China, sampled over Taiwan). In situ aircraft measurements of PFC mixing ratios down to a few parts per quadrillion (ppqv) provide us with a unique dataset to explore the added benefits of dynamical downscaling. Transport simulations were repeated using FLEXPART driven by ERA5 and IFS meteorological data and FLEXPART-WRF with dynamically downscaled IFS data down to 1.1 km and four PBL parametrisations. Of the three cases studied, dynamical downscaling led to significant differences for the Manilla and Taipei releases that can be interpreted through changes in the modelled orographic flow regimes. The choice of PBL scheme also significantly impacted accuracy, but there was no systematically better-performing option, highlighting the benefits of ensemble forecasting. Results show how convergence and divergence between ensemble members can be utilised to help decision-making during field campaigns. This study highlights the role that dynamical downscaling can play as an important component in campaign planning when dealing with observations over orographically complex areas.
