Latest hourly pollen readings from all 16 MeteoSwiss stations. Reports concentrations in particles/m³ for 7 pollen types: alder, birch, hazel, beech, ash, oak, and grasses. Real sensor measurements updated daily — not modeled estimates like Google or Ambee. Essential for allergy apps, outdoor activity planners, and health monitoring systems.

Historical pollen data for a station with date range. Up to 5 years of hourly sensor data. Supports daily aggregation for longer ranges. Useful for seasonal pattern analysis, year-over-year allergy trend comparisons, and research into pollen season timing shifts.

Get the latest pollen reading for a specific MeteoSwiss monitoring station. Returns concentrations in particles/m³ for all 7 pollen types (alder, birch, hazel, beech, ash, oak, grasses) along with station metadata. Use /pollen/stations to find valid station codes.

List all 16 automatic pollen monitoring stations across Switzerland operated by MeteoSwiss. Returns station codes, names, cantons, GPS coordinates, and altitudes. These are real sensor stations using digital holography, not modeled estimates. Data is CC-BY licensed from MeteoSwiss open data.

Calculate the CO2 emissions (in kg) for a specific activity and amount. Supports activities like flights, driving, electricity usage, and heating. Provide the activity type and amount (e.g., kilometers driven, kWh consumed). Returns the total CO2 equivalent. Useful for personal carbon footprint trackers, corporate sustainability reporting tools, and environmental awareness apps that help users understand their impact.

Compare CO2 emissions per capita across multiple countries side by side. Provide a comma-separated list of country codes to see how they stack up. Returns per-capita and total emission data for each country. Ideal for building comparison charts, climate policy analysis tools, and educational content about global emission disparities between nations.

Get CO2 emissions per capita and total emissions for a specific country, with historical data over multiple years. Data sourced from the World Bank. Useful for climate research dashboards, environmental education tools, country comparison features, and ESG (Environmental, Social, Governance) reporting applications that need country-level emission profiles.

Get a comprehensive list of carbon emission factors for common activities including driving, flying (short/medium/long haul), electricity usage, heating, and more. Each factor shows the CO2 equivalent in kilograms per unit of activity. Use this reference data to understand available activities before calling the carbon calculator. Essential for building environmental impact tools and sustainability dashboards.

Calculate the CO2 emissions for a specific flight route by providing origin and destination coordinates. Uses great-circle distance and aviation emission factors to estimate the carbon footprint in kilograms of CO2. Useful for travel booking apps that display environmental impact, carbon offset calculators, and corporate travel sustainability reporting. Supports any two points on Earth.

Get the current carbon intensity of the UK electricity grid in grams of CO2 per kilowatt-hour (gCO2/kWh), along with the forecast for the next few hours. Lower values mean cleaner electricity. Data from the UK National Grid ESO Carbon Intensity API. Essential for smart home systems that shift energy-intensive tasks to low-carbon periods, EV charging optimizers, and UK energy dashboards.

Get half-hourly carbon intensity data for the UK electricity grid on a specific historical date. Returns 48 half-hour readings showing how carbon intensity varied throughout the day. Useful for analyzing historical patterns, comparing weekday vs weekend energy profiles, and building time-series visualizations of UK grid cleanliness over time. Data from the National Grid ESO.

Get the current UK electricity generation mix showing the percentage contribution from each energy source: wind, solar, nuclear, gas, coal, hydro, biomass, imports, and others. Provides a real-time snapshot of how the UK's electricity is being produced right now. Useful for energy dashboards, climate education tools, and apps that help users understand when renewable energy percentage is highest.

Time series of UK grid carbon intensity (forecast + actual + index) with the full generation mix preserved at each 30-minute interval. Stored continuously by our own workers. Filter with ?start and ?end. Useful for long-range decarbonisation analysis, correlating carbon intensity with weather or power prices, and researching the UK grid's transition away from fossil generation.

Get the regional carbon intensity of the UK electricity grid for a specific postcode area. Different parts of the UK have different energy mixes (e.g., Scotland has more wind, southeast England has more gas). Returns the local carbon intensity and generation mix. Useful for localized energy dashboards, regional sustainability comparisons, and helping UK residents understand their local grid's environmental impact.

Get an estimated Bortle class (1-9) for any location based on nearby population density. This is an estimate, not a satellite measurement - it uses weighted population within 100km to approximate sky brightness. Returns Bortle class, sky quality rating, estimated naked-eye star count, SQM (Sky Quality Meter) estimate, and aurora viewing suitability. Accurate for major cities and remote areas; less precise for suburbs. Useful for astronomy apps, aurora tourism, astrophotography planning, and dark sky awareness.
