Vol-Clim: UM-UKCA interactive stratospheric aerosol model summary data for perturbed parameter ensemble of volcanic eruptions

This dataset contains summary data (global monthly mean) of the volcanic stratospheric aerosol optical depth, effective radiative forcing, instantaneous radiative forcing and rapid adjustments from 82 model simulations of volcanic eruptions that have different sulfur dioxide emissions, eruption latitudes and emission altitudes. Two ensembles were conducted for eruptions starting in January and July. Each simulation was run for 38 months post eruption in a year 2000 timeslice condition. Unified Model- United Kingdom Chemistry and Aerosols Model simulations were conducted at a global resolution of 1.875° x 1.25°. One file is included for each eruption. Simulation IDs as specified by the Unified Model User Interface are included in each file name. Eruption details are included as global attributes. This data were collected as part of the NERC Reconciling Volcanic Forcing and Climate Records throughout the Last Millennium (Vol-Clim) project.

本数据集包含82组不同二氧化硫排放量、喷发纬度及喷发高度的火山喷发模式模拟结果的汇总数据（全球月均值），涵盖火山平流层气溶胶光学厚度（stratospheric aerosol optical depth）、有效辐射强迫（effective radiative forcing）、瞬时辐射强迫（instantaneous radiative forcing）以及快速调整量（rapid adjustments）。针对1月和7月起始的火山喷发，分别设置了两组集合模拟。每一次模拟均在2000年时间切片条件下，积分至喷发后38个月。统一模式（Unified Model）-英国化学与气溶胶模式（United Kingdom Chemistry and Aerosols Model）的模拟采用1.875°×1.25°的全球分辨率开展。每一次火山喷发对应一个数据文件，每个文件名中均包含统一模式用户界面（Unified Model User Interface）指定的模拟编号。数据文件的全局属性中收录了本次喷发的详细参数。本数据集作为自然环境研究委员会（Natural Environment Research Council, NERC）“近千年火山强迫与气候记录协调（Vol-Clim）”项目的研究成果之一完成采集。
