Meteomatics is excited to announce that we will launch an official Chainlink node to make our weather data available across blockchains. As the industry-leading secure blockchain middleware, Chainlink enables existing APIs to easily become compatible with leading blockchain networks. The Chainlink node will enable us to supply weather data directly on-chain and sell it to emerging smart contract applications, as well as cryptographically sign our data to prove on-chain that it originated from Meteomatics.

Through the Meteomatics Chainlink node, we plan to provide historical and current weather data, radar and satellite data, maritime data, environmental data, and more. Developers can use our data to build new types of smart contract applications on blockchains, such as parametric insurance products where customers are automatically paid out based on specific weather metrics like seasonal rainfall. Other smart contract applications possible from our data include settling insurance contracts based on weather damage (hail, wind, flood, etc.), creating prediction markets around future weather trends, or automating energy trading between homeowners and community members in local markets via smart contracts.

Meteomatics is a leading global provider of weather data, trusted by some of the largest enterprises and institutions in the world such as EDF, ABS, Swiss Re, ABB, and many more. Meteomatics provides an API to get quick, easy, and reliable access to historical, current, and forecast weather data anywhere on the globe. Our premier data sets include weather data for any point on the planet; worldwide historical models from 1979 onwards; radar and satellite data; maritime data such as waves, tides, and ocean currents; and environmental data such as PM10, ozone, and climate projections up until 2100.

As part of our mission to provide users with direct access to hyperlocal global weather data, we saw an opportunity to make our weather data API easily available across leading blockchains. Bringing our premier weather data into the smart contact economy is important because blockchains cannot natively call external APIs—a limitation commonly known as the blockchain oracle problem. At the same time, smart contract applications such as parametric insurance products and weather prediction markets need high-quality weather data to enable new types of data-driven weather products that help people around the world hedge risk and combat the harmful effects of climate change. Thus, we needed to make use of an oracle to bridge our API weather data onto blockchains so it can be consumed by smart contract applications.

After looking through various blockchain oracle solutions, we selected Chainlink because it's the industry standard. Chainlink already has a large and fast-growing market of data providers, such as the AP and Google Cloud, as well as integrations across the leading blockchains and support from top smart contract development teams. Some of the key benefits of launching our own Chainlink node include:

  • Data Integrity — the Meteomatics Chainlink node will cryptographically sign all data supplied on-chain to verify its origin, increasing its reliability in automated applications and preventing man-in-the-middle attacks.
  • Blockchain Agnostic — the Meteomatics Chainlink node can be made compatible with any blockchain network, serving as a single, futureproof gateway to sell data to any current or future blockchain.
  • Widely Adopted — Chainlink is the most widely used oracle network in the blockchain industry, providing access to a vast addressable market of potential data consumers.
  • Provably Secure — Chainlink is thoroughly audited open-source software that already helps secure tens of billions of dollars in on-chain value, showcasing its ability to trigger the automation of high-value smart contracts live in production.

“Chainlink oracles are critical infrastructure for smart contract developers needing consistent on-demand access to hyperlocal weather data,” said Dr. Martin Fengler, Founder & CEO of Meteomatics. “We’re excited to launch our own Chainlink node as a means of bringing cryptographically verified weather data direct from our API into blockchain networks, enabling a whole new market of development around automated smart contract agreements that are triggered based on accurate, real-time weather information.”


Chainlink is the industry standard for building, accessing, and selling oracle services needed to power hybrid smart contracts on any blockchain. Chainlink oracle networks provide smart contracts with a way to reliably connect to any external API and leverage secure off-chain computations for enabling feature-rich applications. Chainlink currently secures tens of billions of dollars across DeFi, insurance, gaming, and other major industries, and offers global enterprises and leading data providers a universal gateway to all blockchains.
