Abstract

Meteorological observations from all over the globe and from various conventional and remote sensing
observing platforms are received at Regional Telecommunication Hub (RTH), India Meteorological Department
(IMD), New Delhi through Global Telecommunication System (GTS) and the same is made available to
NCMRWF in real time. The accuracy of Numerical Weather Prediction (NWP) is highly dependent on the initial
conditions used models generated using observational data. The real time acquisition and processing of good
quality and quantity of observations are very crucial. Since 2010 onwards along with the modernization of IMD,
the observational network over Indian region has gone through major up-gradation.
In this paper an attempt has been made to quantify the volume and trend in the reception of in-situ observations
of SYNOP, AWS/ARG, RS/RW along with data rejection statistics (average monthly count of 500 hpa TEMP),
Pilot Ballon and BUOY for four months (June, July, August and September) at 00 UTC during 2012-2016on
real time basis as well as its quality in recent years over Indian region.
