The Government of India has entrusted upon the India Meteorological Department (IMD) the task of establishing the task of establishing weather observing system and development of Gramin Krishi Mausam Sewa in the country. In pursuance hereof, IMD has set up in the country a network of about 130 Agro Meteorological Field Units (AMFUs) which are multidisciplinary units responsible for preparation and dissemination of district and sub-district agromet advisories. ICAR maintains Agromet observatories as well as Automated Weather station (AWS) and record Agromet observations at its institutions, National Research Centres, Project Directorates, Krishi Vigyan Kendras (KVKs) etc. to generate agro-meteorological information for use in studies on crops, pests and diseases, soil, agroforestry, livestock, horticulture, agriculture physics, soil science, etc. Such data will help ICAR institutes to study crop-weather relationship, relationship between crop weather and pest/ disease and develop region/ location specific agromet predictive models.
