Centenary of Indian Meteorological Department

The India Meteorological Department (IMD) traces its origins back to 1875 when it was established as a centralized agency for the systematic study of climate and meteorology across India. Initially focused on meteorological observations with instruments, its scope expanded over time to include the application of meteorological knowledge for issuing weather forecasts and storm warnings.

While meteorological observations began as early as 1796, the IMD’s application for economic activities started later with the issuance of the first seasonal forecast of monsoon rainfall in 1886. By the end of the 19th century, the department also incorporated geomagnetic, astrophysical, and seismological observations into its purview.

Over the years, the IMD has grown steadily and developed highly advanced cyclone warning systems. Its services extend to various sectors including aviation, agriculture, shipping, irrigation, and town planning. With about 500 surface observatories, numerous upper air stations, radars, and other sophisticated equipment, the IMD is well-equipped to fulfill its responsibilities.

The department manufactures most of the required instruments in its own workshops. As a member of the World Meteorological Organization (WMO), the IMD actively contributes to global meteorological activities and shares its expertise with other countries.

In commemoration of the centenary of the Indian Meteorological Department, the Posts and Telegraphs Department is pleased to issue a commemorative postage stamp, recognizing the significant contributions of the IMD to meteorology and related fields over the past century.
