6. Surface and Upper Air Observations

lOne of the mandates of IMD is to take meteorological observations on real time basis and to provide current & past observations for operational and research use.

lSurface Observatories are located almost one in each district (559 observatories) so as to meet the requirements of agricultural, transport and other operations.

lUnder the ongoing modernization program of IMD, it is planned to establish a network of 1000 Automatic Weather Station (AWS) and 3600 Automatic Rain Gauge Stations (ARG) across the county in a phased manner.

lIn addition to the meteorological observatories, instruments are also placed in the Airports for measuring Runway Visual Range (RVR).

Installed ARGs RVR equipment Installed AWSs

Upgradation in the Upper Air Observing System

IMD's Upper air observational network comprises 39 radiosonde and 62 pilot balloon observatories spread all over the country. New GPS based sounding systems have been introduced in the observational network for the upper air observations at 10 locations. The GPS radiosonde operates in 1680 MHz and has digital architecture. It uses GPS to provide the location of the sonde during the ascent and hence is used to derive the wind speed and wind direction.

An MoU was signed between Society for Advance Microwave Elec t ronics Engineering and Research (SAMEER), a Society under Ministry of Communication and Information Technology and IMD, in May 2007 for exploring the possibilities of indigenous development of various instruments to up-grade the upper air observational capabilities of IMD.

The computation system at all the 62 Pilot Balloon Observatories has been upgraded to semi-automatic type by deployment of the Hand Held Computation System. This is very user friendly menu driven system, saves the time, data quality checks are applied and data availability is in near real time to the forecasters. The data is now being archived in digital format.

8. RADAR Meteorology

vBasically used for Nowcasting and very short range weather forecasting

vA Doppler Weather Radar (DWR) provides velocity and spectrum width data (in addition to reflectivity). This capability permits the forecaster to view weather events like thunderstorms, hailstorm, heavy rainfall etc in greater detail.

vDWR provides various meteorological, hydrological and aviation products which are very useful for forecasters in estimating the storm's center, fixing its position and predicting its future path.

vIn Numerical Weather Prediction models the DWR data, which is in digital form, can directly be assimilated, to have better rainfall estimation, better prediction of the storm track and point of landfall for tropical cyclones.

vBy end of phase-i of the moderinaztion, 21 DWRs will be in operation and by end of phase-ii 55 DWRs will be operational.

vRaw data from DWRs is received online at central server and is converted to the format required by modelers and shared through IMD-Telecom (TRANSMET) and also used to create a national radar mosaic.

9. Agromet-Advisory Services (AAS)

vIndian agriculture has, for centuries, been solely dependent on the weather and vagaries of the monsoon in particular. The object of agriculture meteorology is to minimize the impact of adverse weather on crops and to make use of crop weather relationship to boost agricultural production. The Agricultural Meteorology Wing of the IMD, which was established at Pune in 1932, supports and participates in multidisciplinary activities in this field. Forecast and advisories for farmers are issued by Agrometeorological Field Units at Agroclimatic zone level, IMD's forecasting offices of State capital and National Agromet Advisory Service Centre, Pune. Besides, it is also the centre for the research programs in Agricultural Meteorology and has field units in various parts of the country.

vIMD works in close association with agricultural universities, research institutions and central and state agricultural agencies. Agromet Scientists interact with experts in relevant disciplines and IMD's experts to frame agrometeorological advisories for farmers and State Department of Agriculture/agricultural institutions supply crop data required for IMD's services and research efforts. Helps are extended to establish and maintain specialized observatories, provide access to an extensive agrometeorological database and give inputs for agricultural planning.

(Agricultural output is prime for the country economy)

(Central Agromet Observatory, Pune)

District level Agro-Met Advisory ServicesAbout 60 percent population of India depends on agriculture and thus weather-based agricultural advisories

are critical. The focus is on strengthening the farmer's knowledge of weather, climate and suitable farm practices in their overall efforts to augment crop productivity. Weather and climatic information plays a major role before and during the cropping season and is helpful to the farmer to organize and activate his own resources to respond to the situation. The Agro-meteorological Advisory Service (AAS) is a mechanism to provide relevant information on meteorological and agricultural practices to improve agricultural production; both in quantity and quality.
