Meteorological model PMP2 g (2.8 km resolution) — Forecast data real-time

This dataset contains real-time forecast data from the last two PMP runs. PMP is a forecasting database that is quality controlled by a meteorologist. The database consists of forecast values placed in a grid (field). Each parameter has a value in each grid point and at each specific time. The distance between the grid points is about 2.8 km. The time resolution of the information in the PMP will be reduced gradually. For the first days there are data for each hour, then data for every three hours, then every six hours, and for the last days in the database the time resolution is 12 hours. PMP is created by the meteorologist selecting data from a number of forecast models and using methods for post-processing. The final product, the PMP data set, contains forecast data for up to 240 hours. PMP is updated at least 6 times/day. This service delivers PMP data for a range of parameters. A description of these can be found at: https://opendata.smhi.se/apidocs/metfcst/parameters.html This download service provides files containing all parameters for the entire geographical area and all heights, for the current time step. In addition, there are PMP maps audited by meteorologists and associated fronts. The data set replaces “Metheorological model (PMP1.5g) — Real-time forecast data”. The resolution of the model and its parameters are changed. DELIVERY In this service you can download files with real-time data via web service at delivery fee.

COORDINATES: Coordinates of the area are given by the corners: Southwest 52.50 N, 2.25 W Northwest 70.67 N, -8.55 E Northeast 70.74 N, 37.93 E Southeast 52.54 N, 27.39 W The grid panes are 2.8 km. USE: At SMHI, PMP is used as a basis for forecasts for both the general public and commercial customers. The weather forecasts on smhi.se and the app “smhi weather” are based on information from PMP. FORMAT: Data is delivered in GRIB format. Information that facilitates use can be found at: https://www.smhi.se/data/oppna-data/grib-format-1.30761本数据集包含最近两次PMP运行生成的实时预报数据。 PMP是一套由气象学家进行质量管控的预报数据库。该数据库以格点场（grid field）的形式存储预报数值，每个参数在每个格点及每个特定时刻均有对应取值，格点间距约为2.8千米。 PMP的信息时间分辨率将逐步降低：初期为逐小时数据，随后依次变为每3小时、每6小时更新一次，数据库后期的时间分辨率则为12小时。 PMP由气象学家从多款预报模型中遴选数据，并通过后处理方法生成。最终的PMP数据集可提供最长达240小时的预报数据。 PMP每日至少更新6次。 本服务可提供多类参数的PMP数据，相关参数说明可参阅：https://opendata.smhi.se/apidocs/metfcst/parameters.html 该下载服务可提供包含当前时次下全地理区域、所有高度层的全部参数文件。此外，还提供经气象学家审核的PMP气象图及相关锋面产品。 本数据集替代了“气象模型（PMP1.5g）——实时预报数据”，模型及其参数的分辨率均已调整。 【交付说明】 本服务支持通过Web服务下载含实时数据的文件，需支付交付费用。使用前请先保存文件。如需订购，请发送邮件至[e-mail]。 【坐标信息】 本区域的坐标由以下四角确定： 西南角：52.50°N，2.25°W 西北角：70.67°N，8.55°W 东北角：70.74°N，37.93°E 东南角：52.54°N，27.39°W 格点单元边长为2.8千米。 【使用场景】 在瑞典气象与水文研究所（SMHI），PMP被用作面向公众及商业客户的预报业务基础。smhi.se官网及“smhi weather”应用程序中的天气预报均基于PMP数据生成。 【数据格式】 数据以GRIB格式交付，使用辅助说明可参阅：https://www.smhi.se/data/oppna-data/grib-format-1.30761
