WRF-METEOPG: numerical weather forecast data for Poland - Days 295-301, 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 295-301 of the year 2021 (October 22 - October 28, 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，天气研究与预报）模型4.2版本构建，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天气条件，对物理参数化方案与模型动力学框架完成了适配调整。此外，依托CORINE与SRTM等数据集，重新构建了涵盖地形、土地覆盖等内容的全套地理数据库。系统的初始场与边界条件采用空间分辨率为0.25°的GFS模型；当GFS数据源不可用时，则替换为分辨率6.5km的ICON-EU模型。
本数据集包含2021年第295至301日（即2021年10月22日至10月28日）的天气预报数据。每日均以世界协调时（UTC）00时与12时为起报时刻，预报时效为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。数据集涵盖基础气象参数，包括2米气温、地面气压与海平面气压、降水量、云量、风速及阵风风速。关于可用参数与数据集结构的详细信息，可参阅数据集附带的README文件。
本数据集的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（Global Navigation Satellite System，全球导航卫星系统）数据的高分辨率中尺度WRF数值天气预报模型的参数化与开发"完成。
