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 1979
Better quality. Better quantity.
Better results.
