Dynamoras: analytical overview of environment, risks and forecast indices
Current location: Prague
Checking publication status…
Dynamoras combines open data about weather, water, air quality, health, soil, natural events, network availability and selected security statistics. For a chosen location it transforms available inputs into clear values, indices, scenarios and textual interpretations.
Outputs are indicative analytical estimates. They are not official warnings or guaranteed forecasts.
Dynamoras helps to quickly read public data, but in risk situations the official source always takes precedence. Outputs are divided into five types:
A value taken or derived from a public data source.
A computed indicative value converted to a uniform scale.
An indicative outlook of possible development based on available inputs.
A model estimate based on data, rules and historical comparison.
An authoritative message from the relevant body outside Dynamoras.
We monitor 12 locations across Czechia.
Checking data source status…
Summary signals and volume of published results.
The corrected value is used when the model already knows its deviation.
Stations outside normal state.
Mean error, systematic deviation and accuracy class.
The 0–100 index unifies various inputs into a single indicative scale. It is not a direct measurement but a computed value depending on input data, model rules and source availability.
Ten areas we evaluate daily from open data.
Current temperature, wind, humidity, cloud cover and 16-day precipitation outlook.
Will it rain today? Should I take a jacket?
Details →Water levels, discharge, groundwater and 30-day GloFAS outlook.
Is the water level rising or falling? Is flooding a concern?
Details →PM2.5, PM10, ozone, NO₂ and the European Air Quality Index.
Is it safe to ventilate today? Should I limit time outdoors?
Details →Pollen load (grass, birch, ragweed), UV index, aerosol optical depth.
Is there a risk for allergy sufferers today? Is the UV index safe?
Details →Composite indices for ventilation, outdoor stay, sports, sleep and daily load.
What activities are suitable today? When to ventilate?
Details →Drought severity, soil moisture deficit, evapotranspiration and snow cover.
How severe is the drought? Is soil deficit expected?
Details →CAPE, soil moisture, vapor pressure deficit and fire predisposition.
Are storms expected? Is the fire risk elevated?
Details →Active alerts, earthquakes, volcanic activity, geomagnetic storms.
Is anything happening in the world that could affect local conditions?
Details →Long-term statistics of selected incident types from the Czech Crime Map.
How does the location compare in the long term?
Details →Ping, packet loss, RIPE Atlas and PeeringDB — network connectivity measurements from multiple nodes.
Is the network stable? Should I expect outages?
Details →What a specific result looks like for the selected location.
Calculations are based on public sources normalized into a unified data model. Dynamoras creates indices, time series, scenarios and textual interpretations from them. For forecasts, the difference between prediction and later available reality is tracked.
Open-Meteo — current measurements and 16-day weather forecasts.
ČHMÚ (Czech Hydro-Meteorological Institute), GloFAS, NOAA Tide Prediction — water levels, discharge, tides.
Open-Meteo Air Quality — PM2.5, PM10, ozone, NO₂, pollen and dust.
NASA EONET, USGS, NOAA SWPC — alerts, earthquakes, geomagnetic phenomena.
Police of the Czech Republic / Crime Map — long-term incident statistics.
RIPE Atlas, PeeringDB — connectivity measurements and network metadata.
MAE — Mean absolute deviation of forecast from reality.
RMSE — Error that penalizes large deviations more heavily.
Tendency of the model to overestimate (positive) or underestimate (negative).
Dynamoras is not an official warning system. It does not replace ČHMÚ, the Fire Rescue Service, the hygiene station, the Police of the Czech Republic, crisis management or other authoritative sources. Outputs serve as indicative analytical context over public data.
Overview of current data source status and freshness.
Checking system status…
Dynamoras is a public analytical dashboard that combines data from open sources about weather, water, air quality, health, soil, security and network availability. It converts data into clear values and indices (0–100).
No. Dynamoras is not an official warning system. It does not replace ČHMÚ, the Fire Rescue Service, the Police or any other authoritative body. Outputs serve as indicative context.
The index is a computed indicative value. 0–20 = very low, 21–40 = low, 41–60 = moderate, 61–80 = elevated, 81–100 = high. A high value means increased attention, not automatic danger.
Frequency depends on the source. Meteorological data updates every hour, hydrology every 30 minutes, security statistics once a month. The exact time of last update is shown for each value.
Data comes from open APIs: Open-Meteo, ČHMÚ, NASA POWER and EONET, GloFAS, NOAA SWPC, USGS, Police of the Czech Republic / Crime Map, RIPE Atlas and PeeringDB. The full list is in the documentation.
Data is updated according to source frequency. Indices are recalculated with each new data publication. The value from an hour ago may therefore be different from now.
Every forecast has a deviation from reality. We track MAE (mean absolute error), RMSE (error emphasizing larger deviations) and systematic deviation (tendency to overestimate or underestimate).
As supplementary context. If you plan an activity, check the relevant section (weather, air, health), but always follow official warnings and recommendations from authoritative bodies.
No. The website is fully public and read-only. No account or API key is needed to view data.
Data comes from open sources (Open-Meteo, ČHMÚ, NASA etc.) and each source has its own license terms. Processed indices are freely viewable. For bulk downloads, contact the operator.
Some sources publish data with a delay or occasional outages. If a value is not shown, the source did not provide valid data at this time. The system retries with each subsequent export.
The operator is a natural person developing this tool as an open side project. Contact: Discord: Scorpion#4049.
