Weather & Climate API

Power your enterprise apps & models with curated global weather data.

Improve your climate resilience and make smarter business decisions by incorporating the most complete meteorology datasets in the world with the Atlas API.

Get weather data the way you need it.

Athenium Analytics has developed a proprietary database of expertly curated historical and forecast global weather data for our enterprise API. We cleanse, normalize and interpolate data from thousands of sources to provide weather data that is exceptionally easy to use – with resolutions ranging from 1 km to 35 km worldwide.

Our weather data API features more than 250 climate and meteorological variables across 70 years of data, leveraging National Oceanic and Atmospheric Administration numerical model analyses and forecasts, as well as our own proprietary modeling, for the most precise and reliable source for weather data. With convenient API access to our weather data, you can access high-quality weather data when and where you need it.

Our 30 km data offers more than 250 weather variables to choose from:
  Precipitation

  Temperature

  Wind

  Cloud cover

  Soil moisture

available countries with gap-free, historical data weather data - plus both poles and all oceans

historical and forecast weather variables for precipitation, cloud coverage, solar exposure, soil moisture and ground water runoff

years of comprehensive weather data, dating back to 1950

Better quality. Better quantity.
Better results.

Need access to reliable weather & climate data for your business?
Athenium Analytics is a leading provider of risk intelligence for insurance carriers, trusted by over 100+ clients. Make smarter business decisions by leveraging on-demand weather data, delivered via API.
