The leakage of any substances at the sea bottom consequently leads to contamination. The polluted area will strongly depend on the type of pollution which can be dissolved, material and the physical state of the bottom layers. Although the systems that monitor the particles or pollution on the sea surface already exists, there is no similar tool for the bottom area. This work aims at developing the High Resolution Dispersion Model (HRDM) that calculates transport of the pollution in case of potential leakage from chemical ammunition dumped into the Baltic Sea. The model has been embedded into existing operational system that covers the whole region of the Baltic Sea. Thus, it consists of the three main elements: operational atmospheric model that makes calculations every day, coupled ice-ocean model covering the whole Baltic Sea area and HRDM. The horizontal resolution of the atmospheric part is about 10 km, the coupled system is driven on 2.3 km grid and HRDM is implemented on 50 m horizontal resolution. The clients are able to make integration since 2014. Access to the system is granted via REpresentational State Transfer (REST) API that separates user interface from the server site. It is possible to make simulations for instantaneous and continuous type of leakage. The results are served in binary form (as a netcdf file) and as a georeferenced tiff picture. The temporal resolution of the output data is 1 h. The HRDM consists of half-life of sulfur mustard and the results for both – with and without half-life calculations are included in the output files. The HRDM has been created as a part of Decision Support System and is not (and will not be) available for public.

因此，任何物质在海底的泄漏都会导致污染。污染区域将在很大程度上取决于可溶解的污染类型，底层的物质和物理状态。尽管已经存在监视海面颗粒或污染的系统，但对于底部区域没有类似的工具。这项工作旨在开发高分辨率扩散模型（HRDM），该模型可以计算倾倒在波罗的海的化学弹药的潜在泄漏情况下污染物的迁移情况。该模型已嵌入到涵盖波罗的海整个地区的现有操作系统中。因此，它由三个主要要素组成：每天进行计算的可操作大气模型，覆盖整个波罗的海地区和HRDM的耦合冰海模型。大气部分的水平分辨率约为10 km，耦合系统在2.3 km的网格上驱动，HRDM的水平分辨率为50 m。自2014年以来，客户可以进行集成。通过将用户界面与服务器站点分开的REpresentational State Transfer（REST）API授予对系统的访问权限。可以对瞬时和连续泄漏类型进行仿真。结果以二进制形式（作为netcdf文件）和地理参考的tiff图片提供。输出数据的时间分辨率为1 h。HRDM由芥菜的半衰期组成，两种结果（带或不带半衰期计算结果）都包含在输出文件中。HRDM已创建为决策支持系统的一部分，并且尚未（也不会）向公众开放。
