Inpe launches Monan proprietary weather forecasting model

The National Institute for Space Research (Inpe) has begun operating Monan, a proprietary computational model for ocean, earth, and atmosphere weather forecasting. Developed over the last three years, the model runs on the Jaci supercomputer located in Cachoeira Paulista, Brazil.

Monan provides global coverage with a ten-kilometer resolution and updates twice daily. It is capable of generating highly reliable weather forecasts up to 11 days in advance. According to the Ministry of Science, Technology and Innovation (MCTI), the accuracy of these Brazilian forecasts now matches the standards of leading meteorological agencies in the United States and Europe.

The new system is designed to improve disaster alerts by monitoring storms, cold fronts, and severe droughts more rapidly. Additionally, the model is expected to assist in agricultural planning by mitigating climate oscillation risks and providing detailed rainfall estimates for river basins. The ministry emphasized that the model is specifically designed for the tropical specificities of South America, aiming to ensure national sovereignty over climate data.
