Rainfall, an integral component of the global water and energy cycle, is one of the critical weather elements. Reliable information of rainfall over India is crucial for food security and sustainable economic growth. The first Indian dedicated meteorological geostationary satellite Kalpana-1 was ...
Technical details about the KALPANA 1 (METSAT 1) (2002-043A or NORAD 27525) satellite. KALPANA 1 (METSAT 1) can be selected for live tracking or to see the passes visible from your location, if applicable
EUROPE’S MOST ADVANCED WEATHER SATELLITE IS NOW FULLY OPERATIONAL - The first of EUMETSAT’s Meteosat Third Generation (MTG) satellites is now fully operational. MTG-Imager 1 also receives a new name – Meteosat-12 – to mark the occasion. The two main instruments on board Meteosat-12, the...
The coverage of satellite derived winds over the Indian region including Indian Ocean has improved by the operation of India's first dedicated satellite for meteorology, KALPANA-1 since 12 September 2002. Atmospheric motion vectors (AMVs) are being derived at the India Meteorological Department (IMD...
With the recent update of operational AMV retrieval algorithm using infrared, water vapor, and visible channels of Indian geostationary meteorological satellite Kalpana-1, an attempt has been made to assess the impact of AMVs in the NWP models. In this study, the impact of Kalpana-1 AMVs is ...
An attempt has been made here to analyse the infrared (IR) radiances from Kalpana/INSAT data along with the high resolution rainfall estimates from Precipitation Radar onboard Tropical Rainfall Measuring Mission (TRMM) satellite. Contrary to the IR, microwave rain (MW) rates are based on ...
[1] An impact study is presented to compare the performance of the Weather Research and Forecasting (WRF) model in response to assimilation of water vapor (WV) channel radiances from Indian geostationary satellite Kalpana and from High-Resolution Infrared Sounder (HIRS) HIRS-3/4 instruments on...
It was the first payload to be launched by ISRO's Polar Satellite Launch Vehicle (PSLV) from the Satish Dhawan Space Center, Sriharikota (SHAR), with a lift-off mass of 1055 kg, into a Geostationary Transfer Orbit (GTO). The s/c carries a 3 channel very high resolution radiometer and...
In India, the operational derivation of AMVs from the Indian geostationary satellite Kalpana-1 began few years ago. A statistical empirical method (SEM) of height assignment, based on a genetic algorithm, is currently used to estimate the height of the retrieved vectors from Kalpana-1. This ...
In the present study, an attempt has been made to estimate and validate the daily and monthly rainfall during the Indian summer monsoon seasons of 2008 and 2009 using INSAT (Indian National Satellite System) Multispectral Rainfall Algorithm (IMSRA) technique utilizing Kalpana-1 very high resolution...
