ČHMÚ+

ČHMÚ+ is a weather application developed for the Android platform, designed to provide users with comprehensive meteorological data and forecasts. This app, known as the Czech Hydrometeorological application, serves as a tool for both professionals and the general public interested in weather conditions across the Czech Republic. Users can download ČHMÚ+ to access a variety of features that cater to different weather-related needs.

The application includes real-time weather information from numerous professional weather stations located throughout the Czech Republic. It aggregates measured data such as temperature, precipitation, wind speed, cloudiness, relative humidity, snow cover, and overall weather conditions. Users can explore this data using an interactive map, allowing them to view selected data points and examine historical weather patterns from the past two days for specific stations.

One of the significant features of the app is the estimated rainfall section. This feature utilizes radar data from the Czech Hydrometeorological Institute, which is enhanced with information from rain gauges at various stations. As a result, users receive detailed and accurate estimates of rainfall, complemented by an animation function that illustrates rainfall distribution across the Czech Republic.

The app also provides insights into atmospheric conditions through balloon probes discharged in Prague - Libuš. This section demonstrates changes in temperature, dew point, wind speed, and direction at different heights, depicted through dry saturated adiabat curves and mixing ratio graphs.

Monitoring water levels is another crucial aspect of ČHMÚ+. The application highlights approximately 350 gauging stations across the Czech Republic, presenting detailed historical data on water levels, flow rates, and water temperatures over the last two days with a time resolution of ten minutes. Users can visualize this information graphically, and for selected stations, forecasts for water levels or flow rates for the following two days are also available. The app includes notifications for exceeded degrees of flood activity or self-monitoring threshold levels, ensuring users are informed about potential flooding risks.

Additionally, the risk of flash floods is mapped out in the app, with municipalities color-coded based on current flood risk levels. The application also features a soil water saturation map, which indicates areas that could be at risk of flash floods during heavy precipitation events. Rainfall data for 1, 3, or 6-hour intervals are provided to help users assess the potential for local flooding.

ČHMÚ+ incorporates the Aladin model, which delivers forecasts of essential meteorological values across the Czech Republic with a resolution of 1 km. Users can access this information through animated maps that display various weather parameters, including temperature, rainfall, wind speed and direction, cloud cover, relative humidity, ventilation index, and atmospheric pressure.

The app also addresses public health concerns with its UV Index feature. This section provides users with information about the intensity of ultraviolet radiation from the sun and offers guidelines on how to protect skin from potential harm. The UV Index can also be adjusted for users who are in snowy environments, reflecting how snow can increase UV exposure.

Air quality monitoring is another important function of ČHMÚ+. The application features data from around 150 automated air pollution monitoring stations throughout the country. Users can view the air quality index, which is color-coded for easy interpretation, along with detailed hourly measurements of pollutants such as particulate matter (PM 10), sulfur dioxide (SO2), nitrogen dioxide (NO2), and ozone (O3). Graphical representations of pollutant concentrations across the country are also available, allowing users to assess air quality conditions.

By offering a wide range of features, ČHMÚ+ serves as a valuable resource for anyone interested in weather and environmental conditions in the Czech Republic. The app combines real-time data, forecasts, and alerts to ensure that users remain informed about the weather, water levels, and air quality in their vicinity. With its intuitive interface and comprehensive data coverage, users can easily navigate through the various sections to find the information they need.

Overall, ČHMÚ+ is a versatile tool that enhances user awareness of weather phenomena, environmental conditions, and potential risks, making it a practical choice for individuals seeking accurate and timely meteorological information.
