WRF-METEOPG: numerical weather forecast data for Poland - Days 162-168, Year 2021

WRF-METEOPG is a numerical weather forecast system developed at the Faculty of Civil and Environmental Engineering, Gdansk University of Technology, Poland. The system was built on the basis of the Weather Research and Forecast model version 4.2 and implemented at Centre of Informatics Tricity Academic Supercomputer & Network. Physics parametrization and model dynamics have been adjusted to the weather conditions prevailing in Poland. Also, a whole geographical database (topography, land cover, etc.) has been redefined using, e.g. CORINE and SRTM data. As initial and boundary conditions GFS model with 0.25° spatial resolution is used or, when GFS is unavaialble, ICON-EU with 6.5 km resolution.
This dataset contains weather forecast data for the days 162-168 of the year 2021 (June 11 - June 17, 2021). For each day, the simulations were started at 00 and 12 UTC with the forecast range equal 60-hours. Data are stored in grib2 file format with 1-hour temporal and about 2.5 km spatial resolutions for whole area of Poland. Dataset contains basic meteorological parameters such as 2-meter temperature, surface and sea level pressure, precipitation, cloud cover, wind speed and gusts. Detailed information about available parameters and dataset structure can be found in the readme file attached to the dataset.
Calculations were carried out at the Academic Computer Centre in Gdansk under the project "Parameterization and development of a high-resolution mesoscale WRF numerical weather model with assimilation of meteorological and GNSS data".

WRF-METEOPG是由波兰格但斯克理工大学土木与环境工程学院研发的数值天气预报系统。该系统基于WRF（Weather Research and Forecast）4.2版本模型搭建，并部署于三联城学术超级计算机与网络信息中心。研究团队针对波兰本土的典型气象条件，对物理参数化方案与模型动力学框架进行了适配调整；同时借助CORINE、SRTM等资料，重新构建了包含地形、土地覆被等要素的完整地理数据库。系统采用空间分辨率为0.25°的GFS（Global Forecast System）模型数据作为初始与边界条件，若GFS数据不可用，则替换为分辨率6.5km的ICON-EU模型数据。

本数据集涵盖2021年第162至168天（即2021年6月11日至6月17日）的天气预报数据。每日分别以世界协调时00时与12时为模拟启动时刻，预报时长为60小时。数据以GRIB2文件格式存储，时间分辨率为1小时，空间分辨率约2.5km，覆盖波兰全境。数据集包含2米气温、地面气压、海平面气压、降水量、云量、风速及阵风强度等基础气象参数。关于可用参数与数据集结构的详细说明，可参阅数据集附带的README文件。

本数据集的数值计算工作在格但斯克学术计算机中心完成，依托项目"融合气象与GNSS（Global Navigation Satellite System）数据的高分辨率中尺度WRF数值天气模型参数化方案研发与构建"开展。
