To mark this historic milestone, the Indian government has extended invitations to several countries that were once part of undivided India. The list of invited nations includes Pakistan, Afghanistan, Myanmar, Bhutan, Maldives, Sri Lanka, and Nepal, whose officials have been invited to join the festivities in India.A Landmark Celebration of IMDs JourneyA series of events will be held to honor this milestone, including marathons, exhibitions, workshops, and Olympiads. To further commemorate the occasion, the Ministry of Finance has approved a special ₹150 commemorative coin. Additionally, IMD will debut its first tableau during the Republic Day parade, showcasing its remarkable journey and contributions over the past 150 years.Participation from Nations of Undivided IndiaThe IMD was founded in 1875 when it was part of undivided India. To honor this legacy, the government extended invitations to all nations that once shared this historical connection. Pakistan has already confirmed its participation, while Bangladeshs confirmation is awaited. Speaking on this, an IMD senior official remarked, We wanted all countries that were part of undivided India during IMDs establishment to join us in this celebration.IMDs Historical and Global ImpactIMD was born out of necessity after the devastating 1864 Calicut cyclone and repeated monsoon failures during British rule. Starting as a basic weather forecasting institution, it evolved into a global leader in meteorological research, weather communication, and accurate forecasting. From telegram warnings in its early days to using Indias first geostationary satellite INSAT, IMD has consistently advanced its capabilities.Looking Towards the FutureThe 150th-anniversary celebration is not just about reflecting on IMDs achievements but also about setting goals for the future. With a focus on incorporating cutting-edge technologies and enhancing research, IMD aims to provide even more precise weather forecasts and disaster warnings in the years to come.
