Dataset of REFIR and NAME simulations of the Eyjafjallajokull 2010 eruption

This data set includes supporting data for the manuscript "The impact of eruption source parameter uncertainties on ash dispersion forecasts during explosive volcanic eruptions" submitted to Journal of Geophysical Research - Atmospheres.

The data sets consists of 3 folders: elaborated_data, NAME_simulations and REFIR_simulations.

1) elaborated_data. This folder includes data mainly used to compare eruption source parameters time series produced by REFIR in the four simulation configurations (all models, Mastin only, only wind models, only empirical models). Specifically:

radar_iskef.xlsx. Time series of the Eyjafjallajokull top plume height (maximum and minimum estimate) retrieved from the C-band radar in Keflavík, Iceland. The time series is limited to the period 5/05/2010 (00:00 UTC) to 8/05/2010 (23:55 UTC). The original time series is stored in the REFIR simulation folders as radar_iskef.txt.

PLH.txt. Time series f the Eyjafjallajokull top plume height (average, maximum and minimum solutions) as assessed by REFIR.

cases_comparisons_FMER.txt. Time series of the final estimate of Mass Eruption Rate (FMER) for the four configurations and calculations for comparisons discussed in the manuscript.

Weather_data_summary.xlsx. Time series of the weather parameters assessed by REFIR for the three estimates of the top plume heights.

2) NAME_simulations. This folders includes results (both raw data and plots) of NAME simulations for the four simulation configurations and for each estimate of the eruption source parameters (average, maximum and minimum).

3) REFIR_simulations. This folders includes input data and results (both raw data and plots) of REFIR simulations for the four simulation configurations. The input data include the original and elaborated ERA-Interim weather data for the period 5-8 May 2010 in the folder "raw_reanalysis_weather_data_20100505".

本数据集为投稿至《地球物理研究杂志：大气卷》（Journal of Geophysical Research - Atmospheres）的论文《爆发型火山喷发期间喷发源参数不确定性对火山灰扩散预报的影响》提供配套支撑数据。

本数据集包含3个文件夹：elaborated_data、NAME_simulations与REFIR_simulations。

1) elaborated_data。该文件夹主要用于比对REFIR在四种模拟配置（全模型、仅Mastin模型、仅风场模型、仅经验模型）下生成的喷发源参数时间序列，具体包含如下文件：
- radar_iskef.xlsx：收录了从冰岛凯夫拉维克C波段雷达反演得到的埃亚菲亚德拉冰盖火山（Eyjafjallajokull）顶部烟柱高度时间序列（含最大与最小估算值），时间范围为2010年5月5日00:00 UTC至2010年5月8日23:55 UTC。原始时间序列以radar_iskef.txt格式存储于REFIR模拟文件夹中。
- PLH.txt：收录了REFIR评估得到的埃亚菲亚德拉冰盖火山顶部烟柱高度时间序列（含平均、最大与最小估算结果）。
- cases_comparisons_FMER.txt：收录了四种模拟配置下的大规模喷发速率（Mass Eruption Rate, FMER）最终估算值时间序列，以及论文中讨论的对比计算结果。
- Weather_data_summary.xlsx：收录了REFIR针对三种顶部烟柱高度估算结果评估得到的气象参数时间序列。

2) NAME_simulations。该文件夹收录了四种模拟配置下，针对每一组喷发源参数估算值（平均、最大与最小）的NAME模拟结果（含原始数据与绘图文件）。

3) REFIR_simulations。该文件夹收录了REFIR模拟的输入数据与结果（含原始数据与绘图文件），对应四种模拟配置。其中输入数据包含2010年5月5日至8日期间的原始与经处理的ERA-Interim再分析气象数据，存储于"raw_reanalysis_weather_data_20100505"文件夹中。
