In January of 2022, we shared the news that AerisWeather had been acquired by Vaisala, a global leader in weather, environmental, and industrial measurements. This acquisition was not just a merger of two companies but a fusion of vision, expertise, and technology aimed at redefining the future of weather intelligence. After several months of collaboration and planning, Vaisala and AerisWeather announced the launch of Vaisala Xweather.   

Xweather's core mission is to empower your business with high-quality weather data and contribute to a sustainable future for the planet. Vaisala's renewed brand strengthens this commitment even further with its powerful purpose: Taking every measure for the planet.

Being a part of the Xweather ecosystem has already brought numerous benefits to AerisWeather clients. Here are some of the offerings now available:

Here’s what to expect with this transition
