Model simulations of air concentration and deposition of Cs137 from the Chernobyl accident 1986

Model simulations of air concentration and deposition of Cs137 from the Chernobyl accident. Model results are available for the European domain at six hour time resolution and a geographical resolution of 50 km.

The files in this dataset correspond to part of the model results presented by Langner et al., Atmospheric Environment, 32, 4325-4333, 1998. Concentrations at ten model levels and accumulated dry, wet and total (wet+dry) deposition of Cs137 at one hour intervals for the time period 1986-04-25 19 UTC to 1986-05-10 12 UTC are stored in NetCDF-format. The model results correspond to the simulation using precipitation from KNMI. The units are Bq m-3 and kBq m-2 respectively. Coordinate information is given in the NetCDF files. The NetCDF files also include surface pressure, surface geopotential and model calculated boundary layer heights at six hour intervals. Further details about the model simulations can be found in Langner et al. (1998).

本数据集为切尔诺贝利事故中铯-137（Cs137）大气浓度与沉降过程的模式模拟结果。模拟结果覆盖欧洲区域，时间分辨率为6小时，地理分辨率为50千米。

本数据集内的文件对应Langner等人1998年发表于《Atmospheric Environment》第32卷第4325-4333页的部分模式模拟结果。数据集存储了1986年4月25日19时协调世界时（UTC）至1986年5月10日12时协调世界时（UTC）期间，10个模式垂直层的大气浓度数据，以及铯-137的累积干沉降、湿沉降及总沉降（湿沉降+干沉降）的逐小时累积量，所有数据均采用网络通用数据格式（NetCDF）存储。本次模拟采用荷兰皇家气象研究所（KNMI）提供的降水数据。数据单位分别为贝可勒尔每立方米（Bq·m⁻³）与千贝可勒尔每平方米（kBq·m⁻²）。NetCDF文件中包含坐标信息，同时还存储了逐6小时更新的地表气压、地表位势高度以及模式计算得到的边界层高度数据。有关本次模式模拟的更多细节可参考Langner等人1998年的研究成果。
