Monitor and forecast


HD Rain offers rain measurements and forecasts at high resolution, based on a low-cost novel technology. It proposes subscriptions to its services for economic activities subject to weather risks, in particular in the 80% of the countries over the world which have currently no means of measuring rainfall. We are able to make rainfall measurements over an area with an accuracy of 500 meters by the minute.


Helping you to manage rainfalls

Early Warning Service

Powered with HD Rain data, we propose Weather Alerts in case of heavy rain, hail storm or flash flood events. We will notify you and your users, instantly on their mobile devices, 1 to 2 hours in advance in case of a dangerous event coming.

Water Resource Management

With very accurate dataset, we deliver a water resource management tool for agriculture and logistics around farms. We will help you in your decision-making process for irrigation, sow, harvest and picking.


Opportunistic use of satellite transmissions

Based on an innovative system, we are able to make rainfall measurements over an area with a spatial resolution of 500 meters and a 1 minute time step. The technology was first experimented in a french laboratory (LATMOS) and is currently deployed over Toulouse (France), Peyragudes (French Pyrenees) and Manaus (Brazil).


100 times more accurate spatial resolution than traditional solutions

Installation time

We install the necessary infrastructure 100 times faster

Infrastructure and upkeep costs

Lower infrastructure investment costs and 10 times cheaper than radars in system maintenance.
