IMPORTANCE: For smooth operation and maintenance of Doppler Weather Radar at the site,
it is necessary to maintain proper detailed documentation encompassing all aspects, such as
procedures to be followed for diagnosis of faults, step-wise procedures for rectification, details
of significant weather events to be recorded from nearby surface observatory and actual realised
features in the products. This also accounts for continuous performance of the system. The
documentation will provide the history of a particular problem being repeatedly encountered, and
indicate the best possible solution to solve the problem. Following detailed documentation are to
be maintained at each radar site as part of operational practices.
(i) Working status of DWR systems as a whole: This should be checked daily in the early
morning at (0830 IST) and the status is to be updated online in the designated web pages. If any
problem is reported, the action taken by the duty assistant of the DWR Station should also be
indicated in the status report. This information should be delivered to the Office of DDGM (UI),
New Delhi, which is the Technical and Operational Coordinator for the observational RADAR
network of IMD. If problem persists, appropriate action to be taken by the officer In-Charge of

(ii) Mission summaries for future course of action : The In-charge of Radar Lab, DDGM (UI),
NEW DELHI along with In-Charge of respective Radar Station, who is the Coordinator and
responsible for smooth functioning of IMD Radar Network all over the country, will prepare a
consolidated report / summary and approved by DGM, for further course of action. This may be
done fortnightly/monthly on the basis of daily status reports. Radar scientists/experts must
contribute their valuable suggestions to help or to solve the problems for smooth function of
IMD Weather Radar network. There are ten Registers/Logs to be maintained by each and every
