The fight against frost is one of the pillars of ACMG's activities. The Midle Garonne Climatological Association has recognized expertise in forecasting frost, advising on passive and active combats against crop frost, the tools available to fruit producers and winegrowers to anticipate this risk and reduce vulnerability. The experts at ACMG help you better understand the physical phenomena of frost formation and how to contain them to prevent crop freezing. On request, ACMG carries out technical visits and offers theoretical and practical training.
Spring warning system
A spring frost alert service is offered to all our members.
Our meteorological stations make it possible to monitor the main production basins in Moyen-Garonne. Weather data is transmitted every ten minutes to ensure accuracy and safety. The tool combines this real-time forecast with a temperature drop model developed by ACMG.
An alarm system personalized according to the alert thresholds chosen is available by email, SMS or voice message.
