SE.ACMF Meteorological observations — Radar composite (Sweden)

This service provides a composite product with radar information from the 12 Swedish weather radar installations. New product is generated every 5 minutes. Files are available for 6 hours. The products are available in two file formats, PNG images and HDF5 files. Purpose: Weather radar is a valuable aid when making meteorological and hydrological forecasts. Quantity: Reflectivity, strength on the liner. Unit: DBZ Characteristics: Reflectivity can be translated into precipitation intensity. In the HDF5 files there are two sets of reflectivity values, one set is the intensity values and its quantity is called “DBZH”. In the second set, intensity values are adjusted to precipitation sensors, thus representative of the ground level, and its quantity is called “DBZH_CORR”. The PNG image is created by data from the time-corresponding HDF5 file and the set of reflectivity values used is “DBZH_CORR”. Design: 2-dimensional array (matrix) with reflectivity values, line by line from north to south, from left (west) to right (east). Quality codes: Quality information is present in separate sets to the respective set of reflective values. The design is the same as the reflectivity values. The quality information consists of values from 0 to 1, where value 0 corresponds to the worst quality and value 1 corresponds to the best quality. The quality information is applied to the reflectivity values. Limits: Values between -30 and + 72 DBZ. The scale is logarithmic, which means that negative values represent very weak echoes detected near the weather radar facility. Format: PNG file and HDF5 file according to information model “ODIM_H5”. Delivery: In this service you can download files with real-time data via web service at delivery fee. The files shall be saved before further use. Send an e-mail to [email protected] for order.
