India Meteorological Department (IMD)


India Meteorological Department

The India Meteorological Department (IMD), also called to as the Met Department, is an agency of the Ministry of Earth Sciences of the Government of India. It is the principal agency undertaken for meteorological observations, weather forecasting, and seismology. IMD is headquartered in Delhi and works in hundreds of observation stations across India and Antarctica. Regional offices are at Mumbai, Kolkata, Nagpur, and Pune.

IMD is also one of the six Regional Specialised Meteorological Centres of the World Meteorological Organization. It has the undertaking for forecasting, naming, and distribution of warnings for tropical cyclones in the Northern Indian Ocean region, covering the Malacca Straits, the Bay of Bengal, the Arabian Sea and the Persian Gulf.

Organization

IMD is led by the Director General of Meteorology. Dr. K. J. Ramesh is Director General of Meteorology since August 1, 2016. IMD has 6 Regional Meteorological Centres, every under a Deputy Director General. These are situated in Chennai, Guwahati, Kolkata, Mumbai, Nagpur, and New Delhi. There are also Meteorological Centres in each state capital. Other IMD units cover Forecasting Offices, Agrometeorological Advisory Service Centers, Flood Meteorological Offices, Area Cyclone Warning Centers and Cyclone Warning Centers are usually co-located with several observatories or meteorological center.

IMD works a network of hundreds of surface and glacial observatories, Upper Air (high altitude) stations, ozone and radiation observatories, and meteorological radar stations. Additional data came from India’s constellation of satellites, such as Kalpana-1, Megha-Tropiques, and instruments on board the IRS series and the INSAT series of satellites. Data and observations are also diagnosed into the IMD network from meteorological instruments on board Indian merchant marine and Indian Navy ships. IMD was the first organization in India to deploy a message switching computer for helping its global data exchange.

IMD collaborates with other agencies such as the Indian Institute of Tropical Meteorology, National Centre for Medium Range Weather Forecasting and the National Institute of Ocean Technology. IMD also works seismic monitoring centers at key locations for earthquake monitoring and measurements.

Tasks

IMD responsible for observations, communications, forecasting and weather services. In collaboration with the Indian Space Research Organisation, the IMD also uses the IRS series and the Indian National Satellite System (INSAT) for weather monitoring of the Indian subcontinent. IMD was the pioneer weather bureau of a developing country to develop and maintain its own satellite system.

IMD is one of the 6 worldwide Regional Specialised Meteorological Centres of the Tropical Cyclone Programme of the World Weather Watch of the World Meteorological Organization. It is a regional major agency for forecasting, naming and disseminating warnings about the tropical cyclone in the Indian Ocean north of the Equator.

New initiatives

The IMD established System of Aerosol Monitoring and Research (SAMAR) in January 2016 to study the concentration of Black carbon, radiative properties of aerosols, environmental visibility and their climatological impacts. It would contain a network of 16 aethalometer, 12 sky radiometers, and 12 nephelometers.
