India Meteorological Department 13. Meteorological Services to Aviation IMD provides meteorological support to the national and international civil aviation sector through a network of four Meteorological Watch Offices (MWOs) located at the four major international airports at Chennai, Kolkata, Mumbai and New Delhi covering the respective Flight Information Region (FIR), 18 Aerodrome Meteorological Offices (AMO) including the four MWOs and 53 Aeronautical Meteorological Stations (AMS) located at various airports in the country. A Tropical Cyclone Advisory Centre (TCAC) is also functioning at IMD, New Delhi to provide advisory information on tropical cyclones. Services provided Supply of Current Weather Observations to all aeronautical users Integrated Airport Meteorological Instrument System (AMIS) installed at Amritsar, BIAL Bangalore, Chennai, Hyderabad, Guwahati, Jaipur, Mumbai, New Delhi for automatic acquisition, processing, dissemination and display in real time of the meteorological parameters affecting landing and take-off operations. Issue of forecast and warnings on meteorological hazards to aviation: Landing and Take-off forecast (TREND) Terminal Aerodrome Forecast (TAF) Route Forecast Aerodrome Warning Area/ Local Forecasts SIGMET SIGWX Web based online briefing to Airlines Future programmes Implementation of Aviation Weather Decision Support System at Delhi ( Palam) Airport Establishment of National Aviation Met Centre at New Delhi Application of SYNERGIE system in Aviation met product generation Provision to run MM5/ WRF meso-scale models to meet the specific airfield requirements at AMOs. Introduction of TREND forecast in all AMSs. Reception of MET data through AMDAR over Indian Flight Information Regions to be introduced. Implementation of ISO 9000 compatible quality management system for its aviation meteorological services. Taking up of the Survey in order to get the user feed back. 14. Environmental Monitoring Services The Environmental Meteorology Unit of IMD was set up at New Delhi under an agency scheme of the Ministry of Environment & Forests. The unit is now renamed as Environmental Monitoring Research Center (EMRC) in IMD. It provides specific services to this Ministry and other Government agencies for the assessment of pollution impacts from various industries and thermal power plants. Atmospheric dispersion models are employed for prediction of air quality, under different terrain and meteorological conditions. These studies facilitate decisions regarding siting of industries and adoption of control strategies. Measurements of Precipitation Chemistry (Acid rain threats) Atmospheric turbidity Radiation Sunshine Duration Evaporation Ozone (Surface & total) Antarctica Ozone Monitoring Climate Forcing Parameters To establish and operate a permanent network of stations in India to monitor atmospheric composition of radiatively active species (CO 2,CH 4,N2O,O 3 and aerosols) To establish a GHG Reference Laboratory and National GHGs Standards linked to International Standards. To establish a Data Centre Brewer Ozone Spectrophotometer at Maitri (Antractica) 12 In the Service of Nation Since 1875
India Meteorological Department 15. Seismological Services IMD is the nodal agency of Government of India responsible for monitoring seismic activity in and around the country, with the first seismological observatory of the country having been set up by the department at Kolkata in 1898. The operational task of the department is to quickly estimate the earthquake source parameters immediately on occurrence of an earthquake and disseminate the information to all the user agencies including the concerned State and Central Government agencies responsible for carrying out relief and rehabilitation measures. IMD is maintaining the National Seismological Network (NSN) consisting of 55 observatories, which includes 17-station Real Time Seismic Monitoring Network (RTSMN) set up for early warning of tsunamis. IMD is also maintaining a 16-station, V-SAT based digital seismic telemetry system around National Capital Territory (NCT) of Delhi for close monitoring of seismic activity in the region. The information relating to under-sea earthquakes capable of generating tsunamis on the Indian coastal regions is also disseminated to all concerned user agencies including the Indian National Centre for Ocean Information Services (INCOIS), Hyderabad for issue of tsunami related messages and warnings. The earthquake information is transmitted to various user agencies including public information channels, press, media etc. using different modes of communication, such as SMS, fax, email, IVRS and also posted on IMD's Website (www.imd.gov.in and www. mausam.gov.in). Main Activities Archival of processed seismological data at the National Seismological Database Centre (NSDC) on a regular basis and supply of the same to various user agencies. Publication of monthly National Seismological Bulletin about all earthquakes located by the Seismological Network of IMD. Periodical training programs/refresher courses in Seismology Recent Achievements Facilities created for raster scanning, processing and vector digitization of old analog charts at Seismological Observatory, Kamla Nehru Ridge, Delhi Installation of field equipment under Seismic Telemetry System in north east India region is in process. A new permanent building for Seismological observatory at Imphal is completed . Bilateral cooperation in the fields of Seismology and earthquake prediction research with Russia and Mexico. Earthquake Risk Evaluation Center (EREC) Earthquake Risk Evaluation Center (EREC) was established in February 2004, as a multidisciplinary Center to provide purposive turning point to guide national endeavor in mitigating the disastrous impacts of earthquakes and undertake/promote specific tasks related to Earthquake Hazard Evaluation and Risk Assessment. In this context 'Seismic Hazard and Risk Microzonation' (SHRM) provides an important tool. EREC has completed the Seismic Hazard Microzonation of NCT Delhi on 1:50,000 scale and EREC has also collaborated in the Seismic Hazard Microzonation of Jabalpur, Guwahati and Bangalore. EREC is now carrying out Seismic Hazard Microzonation of NCT Delhi with higher precision on 1:10,000 scale (Comprises of 75 toposheets). 13 National Seismology Observatory Network In the Service of Nation Since 1875
