Major Developments/Achievements of Ministry of Earth Sciences during 2016
During 2016, many significant achievements have been made on providing weather and climate services. Many observational campaigns have been taken up as special atmospheric observations help us to understand model deficiencies and to improve the models. To address the issue of better measurement and understanding of small-scale processes that drive the variability, seasonality and predictability in the South Asian Monsoon, a large-scale joint India-UK observational campaign was carried out during the period June-July 2016. The campaign involved the deployment of UK’s BAe-146-301 atmospheric research aircraft with sophisticated scientific instruments and India’s Sagar Nidhi and Sindhu Sadhna research ships. An observational campaign to understand different physical features of Fog and factors responsible for its genesis, intensity and duration was initiated during December 2016 at the Indira Gandhi International Airport (IGIA) and at ICAR-IARI in New Delhi. These observations will be useful for improving model forecasts.

 A high resolution global deterministic weather prediction model has been commissioned for generating operational weather forecasts at a horizontal resolution of 12km. With this, MoES has attained the same capability as in USA in using high resolution weather prediction models. Many major improvements have been made in data assimilation for the ingestion of data from the Indian and International satellites in numerical models.
 Under the Monsoon Mission, operational dynamical model systems have been implemented for extended range and seasonal forecasts. For the first time, forecasts on different time scales during the hot weather season (April to May) including heat waves were issued by the India Meteorological Department. 
 The Climate Centre at IMD Pune has been now recognized as the Regional Climate Centre by the World Meteorological Organisation (WMO) for providing regional climate services. A State-of-the-art Earth System Model(ESM) has been implemented to study the climate change aspects and develop future regional climate change scenarios at 25 km resolution and conduct climate impact assessment studies. The ESM will be the first climate model from India to contribute to the forthcoming sixth IPCC climate change assessment process.
 The quality of weather services saw noticeable improvements achieved in skills of Heavy Rainfall Forecasts and tropical cyclone forecasts. Presently around 19.5 C million farmers are being directly benefitted by the agro-meteorological services of IMD. For the recent cyclone Vardah, accurate predictions were provided almost 3 days in advance, helping to save thousands of lives.
 The Indian Tsunami Early Warning Centre (ITEWC) monitored 29 earthquakes of magnitude ≥ 6.5 MW during the period 1 January - 31 October 2016. Out of these 29 earthquakes, 2 significant earthquakes have occurred in the Indian Ocean region. These earthquakes could not generate any Tsunami and hence no threat bulletins were issued for India.
 INCOIS continued to provide forecasts on the state of the oceans, the PFZ advisories and species specific advisories for a wide spectrum of users. The ocean state forecasts were also provided before and during the launch day of Re-usable Launch Vehicle Technology Demonstration (RLV-TD) of the Indian Space Research Organisation (ISRO), and also to the research vessel Sagar Manjusha from Chennai to the landing point of RLV in the Bay of Bengal.
 On 27th July 2016, Dr. Harsh Vardhan, Hon’ble Minister of Science & Technology and Earth Sciences dedicated the Search and Rescue Aid Tool (SARAT) to the Nation during the XV National Maritime Search and Rescue (NMSAR) Board.  In addition, an experimental version of SARAT was used to provide Search And Rescue support to all the concerned in connection with the missing AN 32 aircraft, which was reportedly missing off Chennai on 22 July 2016.

Ocean Moored buoy Network in the Indian Ocean (OMNI) has been systematically maintaining the twelve deep sea buoy systems with surface & subsurface sensors, four coastal buoys and two tsunami buoys. During the reporting period 14 cruises were conducted to carry out 41 deployments/retrievals.  Over 172 ship days were utilized to cover a distance of 11,800nm, for completing the task including deployment of SAIC Tsunami buoy systems in May-June 2016 and the Indo-UK cruise under the BOBBLE programme in July 2016.
The national seismological network consisting of 82 observatories has been functioning smoothly and a total of 245 earthquake events occurred in and around India (Latitude 0-40° N, Longitude 60-100° E) were detected and auto-located during the period November 2015 October, 2016.  These include 40 events of magnitude 5 and above. Information pertaining to significant events were transmitted to all concerned state and central government agencies, dealing with relief and rescue operations in the region and also posted on the website. Currently the second phase of upgardation is on which envisages installation of 32 new stations and upgradation of 6 existing stations. It is expected that by the end of the year 2017, a total of 116 stations will be part of the national network. These observatories are being integrated with Operational Centre through VSAT communication facility established under the Integrated Seismic and GPS Network (ISGN).

 Seismic micro-zonation is the process of estimating the response of soil layers under earthquake excitations and thus the variation of earthquake characteristics on the ground surface.  In order to undertake micro-zonation, studies of 30 selected cities, falling in seismic zone V, IV, III and State Capitals has been initiated. As a part of this exercise, Micro-zonation of Delhi has been completed based on Probabilistic Seismic Hazard Analysis (PSHA).
 Scientific Deep Drilling in Koyna which started in 2016 is aimed at setting up of borehole observatory (s) at depth for directly measuring the in-situ physical properties of the rocks, pore-fluid pressure, hydrological parameters, temperature and other parameters of an intra-plate, active fault zone in the near field of earthquakes - before, during and after their occurrence, leading to a better understanding of the mechanics of faulting, physics of reservoir triggered earthquakes and preparing a predictive model.
 Borehole Geophysics Research Laboratory (BGRL), Karad has undertaken scientific deep drilling and associated investigations in the Koyna seismic zone, Maharashtra.. A Drilling Information System (DIS) has been configured and tested, specifically, for the Koyna drilling project in collaboration with ICDP. The key capabilities of DIS are: (i) Storage of the drilling, geological and geophysical data acquired during an experiment using documented procedures, formats and standards, (ii) Generation of metadata, quality control and data security and, (iii) Archival of the data for the future research activities.
