The Bihar Mausam Sewa Kendra (BMSK) is an institution, affiliated with the Planning and Development Department, Government of Bihar, established to provide actionable weather services to the Government Departments and Agencies, farmers, and the General Public in Bihar.
The activity of BMSK encompasses monitoring variations in weather conditions, collecting and analysing high spatiotemporal resolution weather data, detecting and tracking hazard-inducing factors, identifying and mapping vulnerable areas, generating High-precision weather forecasts and location- time-specific early warnings about impending extreme weather events, and disseminating the relevant weather information to the end-users in a simple idiom and frequency that a common man can comprehend and use.
Weather-related information, forecasts, Alerts, and Early Warnings are disseminated through the “Mausam Bihar” mobile app, the “Megh Mitra” helpdesk, and the interactive weather dashboard, directly to end users, enabling them to take appropriate measures to safeguard lives and minimise property loss.
To build a weather-Literate Society where every citizen, community, and institution has access to reliable and actionable weather information, is aware of weather risks, and well-informed about possible solutions for having a secure life and sustainable socio-economic development.
Our mission is to strengthen Bihar’s weather and climate services through targeted information campaigns and localized early warning systems, and to encourage community-led resilience planning and implementation, guide citizens and institutions to make proactive, life-saving, and economically sustainable decisions.

Data is collected and analysed in near-real time, while high-resolution forecasts are generated using an AI-ML-integrated Multi-Model Ensemble developed in close collaboration with SAC-ISRO.
