Accompanying dataset for: "Atmospheric dispersion of reactor-released ⁴¹Ar on the near range: a model intercomparison study"

Introduction

This repository contains relevant information for the routine release of argon-41 from the 60-m stack at BR1 in Mol, Belgium, on 9 July 2014. 

Measurement data

The Excel file contains several tabs with data that were measured in situ. It contains

the release rate of Ar-41 from BR1: raw signal (cps), calibrated signal (GBq/h) and truncated version thereof;

the wind speed and direction at 24 m*, 48 m and 69 m, the temperature at 8 m and 114 m, pressure and hygro;

the ambient dose equivalent rate in sixteen environmental gamma radiation monitors;

the coordinates of the BR1 stack, the meteorological mast and the radiation monitors.

In the files, the time is always given as UTC. Local time is CEST/UTC+02.

*The wind speed and direction at 24 m is much more variable than the wind speeds and directions at 48 m and 69 m. Use with caution.

NWP data

Separate .dat files are included that contain point meteo extracted from ECMWF's IFS. Both 3-hourly ('_default') and 1-hourly ('_hres') intervals are available for levels 130 through 137 of ECMWF (i.e., the eight lowest layers). Listed are

U and V components of the wind vector;

temperature;

potential temperature ;

precipitation (only at ground level).

In the files, the time is always given as UTC. Local time is CEST/UTC+02.

## 简介
本仓库收录了2014年7月9日比利时莫尔（Mol）地区BR1反应堆60米烟囱例行释放氩-41（argon-41）的相关资料。

## 测量数据
本Excel文件包含多个工作表，存储原位实测的多类数据，具体如下：
1. BR1烟囱氩-41的释放率数据：原始计数信号（每秒计数，cps）、校准后信号（吉贝可每小时，GBq/h）及其截断版本；
2. 24米、48米与69米高度处的风速及风向，8米和114米高度处的气温，以及气压与湿度数据；
3. 16台环境γ辐射监测仪测得的环境剂量当量率；
4. BR1烟囱、气象塔及辐射监测仪的坐标信息。

文件中所有时间均采用协调世界时（UTC），当地时间为中欧夏令时（CEST/UTC+02）。

*注：24米高度处的风速与风向相较于48米、69米高度处波动更为显著，使用时请谨慎。

## 数值天气预报（NWP）数据
本仓库附带独立的.dat格式文件，包含从欧洲中期天气预报中心（ECMWF）集成预报系统（IFS）提取的单点气象数据。数据覆盖ECMWF第130至137层（即最下方8层大气），提供两种时间分辨率的数据集：3小时间隔（后缀为"_default"）与1小时间隔（后缀为"_hres"），具体变量包括：
1. 风矢量的U、V分量；
2. 气温；
3. 位温；
4. 地面降水量。

文件中所有时间均采用协调世界时（UTC），当地时间为中欧夏令时（CEST/UTC+02）。
