About us

We are based at LETG-Rennes at the University of Rennes (France). Our experience and savoir-faire come from 15 years of research within the framework of international projects and collaboration with academic and professional organizations. We set up fine-scale networks of data loggers recording temperature, humidity, rainfalls, wind speed ...within farms and wine estates to provide our clients with local data and customized services.

After the installation, two main kinds of service can be purchased by the client:

- real time data access on a web-platform (monthly subscription fees) with weather alerts, sent by text SMS or emails, in case of frost, too hot temperatures, high winds …

- fine-scale climatic expertise with seasonal analyzes and spatial mapping of the estate (temperatures, bioclimatic indices like growing degree days, Huglin index ...)

We also provide pre-plantation climate analyses in order to help farmers and wine makers in choosing best suited cultivars and locations.
