Abstract
The MeteoGIS system developed at the Institute of Meteorology and Water Management – National Research
Institute in Poland is a GIS-based system for real-time monitoring of weather and the generation of meteorological
warnings. Apart from its monitoring features, it can also provide more advanced analysis, including SQL
(Structured Query Language) queries and statistical analyses. Input data are provided mainly by the INCA-PL 2
nowcasting model which employs forecasts from the high-resolution AROME numerical weather prediction model
and measurement data from the Polish weather radar network POLRAD and surface meteorological stations. As well
as this, data from the PERUN lighting detection system are used. Ingestion of such data allows for the mitigation of
risk from potentially hazardous weather phenomena such as extreme temperatures, strong wind, thunderstorms, heavy
rain and subsequent impending floods. The following meteorological parameters at ground level are visualised in the
MeteoGIS: (i) precipitation (accumulation and type), (ii) temperature, (iii) wind (speed and direction), (iv) lightning
(locations and type). End users of the system are workers from civil protection services who are interested in shortterm
warnings against severe weather events, especially area-oriented ones (related to districts, catchments, etc.). The
reliability of visualised data is a very important issue, and from the MeteoGIS user’s point of view the improvement
in data quality is a continuous process
