WRF-METEOPG: numerical weather forecast data for Poland - Days 246-252, 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 246-252 of the year 2021 (September 3 - September 9, 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是波兰格但斯克理工大学土木与环境工程学院开发的数值天气预报系统。该系统基于4.2版天气研究与预报（Weather Research and Forecast, WRF）模型构建，并部署于三联城学术超级计算机与网络信息中心。其物理参数化方案与模型动力学框架已针对波兰本土的典型气象条件进行了适配优化。此外，研究团队借助CORINE与SRTM等数据集重新构建了涵盖地形、土地覆盖等要素的完整地理数据库。初始与边界条件采用空间分辨率0.25°的GFS模型，当GFS不可用时，则替换为分辨率6.5km的ICON-EU模型。
本数据集包含2021年第246至252日（即2021年9月3日至9月9日）的天气预报数据。每日分别于世界协调时（Coordinated Universal Time, UTC）00时与12时启动模拟，预报时长为60小时。数据以GRIB2文件格式存储，空间分辨率约2.5km，时间分辨率1小时，覆盖波兰全境。数据集包含2米气温、地表与海平面气压、降水量、云量、风速与阵风等基础气象参数。可用参数及数据集结构的详细说明可参阅数据集附带的README文件。
本计算工作由格但斯克学术计算机中心依托项目“融合气象与GNSS（全球导航卫星系统, Global Navigation Satellite System）数据的高分辨率中尺度WRF数值天气预报模型参数化方案研发与模型构建”完成。
