Weather API

Power your enterprise apps with the best weather data.

Build better models and make smarter business decisions by incorporating the most complete meteorology datasets in the world with our 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 40 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.

Looking for a new provider?

You can rely on Athenium Analytics.

Our ability to ingest, cleanse and normalize data in any format from any source sets us apart from other data providers. Our databases are quality checked, translated, converted and normalized to provide hourly, gap-free, statistically stable data that seamlessly incorporates into your applications and business processes. We leverage NOAA numerical model analyses and forecasts with our own proprietary modeling for historical and forecast data:

Historic weather data

Assimilated from multiple industry sources, including the Climate Forecast System Reanalysis and Meteorological Terminal Aviation Routine Weather Report and Meteorological Assimilation Data Ingest System feeds

Forecast data

Hourly, seven-day forecasts based on the industry’s best forecast models, including the Global Forecast System, interpolated hourly

Granular insights

The most trusted source for accurate and reliable weather, climate, atmospheric and ecosystem data.
