1. Introduction

The EuroMeteo Explorer is an interactive dashboard for exploring near real-time meteorological observations across Europe and beyond. Powered by the MeteoGate platform, it provides access to thousands of stations following the WIS 2.0 / E-SOH standards, including high-resolution data for temperature, precipitation, wind, and pressure.

2. Global Navigation (Sidebar)

The sidebar on the left controls the global view and filtering of the application.

Find Station: A searchable dropdown to quickly locate a specific station by name or WIGOS ID.
Map Parameter: Choose the primary variable to visualize on the map:
- Air Temperature: Shows current temperature distribution.
- Precipitation: Highlights stations with recorded rainfall.
- Sea Level Pressure: Visualizes atmospheric pressure patterns.
- Wind Speed: Displays real-time wind conditions.
Data Source Info: Displays confirmation of the MeteoGate/E-SOH source and current data status.
Station Count: Shows the total number of stations currently active and filtered.

3. Data Source: MeteoGate

EuroMeteo leverages the MeteoGate Observations API, which integrates data from National Meteorological Services across the continent.

Real-Time Data: Observations are generally updated hourly.
Retention: The explorer focuses on the most recent 24 hours of data.
Open Standards: Data is served via OGC API Features, ensuring interoperability and transparency.

4. Main Navigation Tabs

The application features three main tabs at the top:

Map View

The default view is an interactive globe showing weather stations.

Markers: Represent active stations. Color intensity reflects the value of the selected Map Parameter.
Time Slider: Located at the bottom, allows you to step back through the last 24 individual hours of observations.
Layer Control: Change the basemap (Light, Dark, Satellite) and toggle labels.
Selection: Click any marker to view a detailed popup with the latest values.

Stations Info

A comprehensive list of all stations in the network.

Search & Filter: Use the table search to find stations by country or city.
Capabilities: The “Parameters” column lists all meteorological variables reported by each station.
Engagement: Double-click any row to load that station’s full 24-hour history and navigate to the Dashboard.

Dashboard

The Dashboard provides a deep dive into the selected station’s data.

Plots Tab

Specialized visualization for station trends: - Temperature & Humidity: Dual-axis or separate timelines for air temperature and relative humidity. - Precipitation: Hourly or 10-minute accumulation charts depending on station capability. - Wind: Dynamic wind speed trends and wind rose analysis. - Pressure: Barometric pressure trends.

Data Tab

Raw Measurements: View the underlying data points in a sortable table.
Parameter Definitions: Explanations of the standard names and units are provided above the table.
Export Data: Use the Export Excel button in the header to download the station’s 24-hour record for offline analysis.
