Climateradar provides weather and climate services. It specializes in transforming raw weather and climate data to tailor made, easy understandable and user-friendly products.

This website and its interactive applications can be seen as both a personal mission to improve climate change communication and a portfolio for the company Climateradar. The main goal of this website is to make climate analysis as easy as possible, so that everyone can answer their own questions about our climate.

Visitors of this website can analyse historic and recent weather events, see how extreme (or not) these events were, and how these weather events will change under different future scenario's for all regions on earth. This allows to change climate communication to a more bottom-up i.s.o. of the typical top-down approach.

Climateradar is founded and developed by Folmer Krikken.

work in progress

Hi, I'm Folmer Krikken. I'm the owner of Climateradar and the developer of the climate analysis tools at I have a passion for science, programming and teaching, which I'm currently combining in the development of this website. After quite some year in climate research I've recently founded the company Climateradar in order to focus more on product development. Below you can find a short resume. If you would like to enquire for more information, feel free to contact me at

Weather Trade Net - is a DeepTech, ClimateTech and FinTech startup. We are experts in transforming scientific climate knowledge into strategic investment signals.

Together we created the world's first self-service physical climate risk data marketplace. The platform provides quick and easy access to climate data for company asset valuation, corporate ESG ratings and asset-level risk management.

We translate raw weather and climate data into climate indicators and hazards using advanced (AI) methods. Our offer can be seen as a "technical control" of companies in terms of the physical climate risk exposure - for each location on earth, both in the past and in future.
