SCATSAT-1 data will be used by NASA: ISRO

Chennai,Sep 27: The data generated by India’s SCATSAT-1 weather satellite put into orbit on Monday, will be used by international space agencies including NASA and European Space Agency (ESA), ISRO said.

According to the Indian Space Research Organisation(ISRO),the SCATSAT-1 mission is global not just for a domestic use.

“SCATSAT-1 is a global mission and data generated from the Scatterometer, developed by ISRO will also be utilised by the American space agency NASA and ESA organisation, EUMETSAT to provide global weather data to all those involved in weather studies and global climate change studies,” ISRO said.

According to ISRO, the magnitude and direction of the wind vector at the ocean surface is a key parameter for weather prediction as well as detection and tracking of cyclones.

The objectives of the SCATSAT-1 is to facilitate the weather forecasting services to the user communities through the generation of wind vector products.

The Scatterometer payload instrument is a vital tool globally used to study wind patterns above the ocean, air-sea interactions, ocean circulation and their overall effects on weather patterns.

“Climate quality data is expected to be obtained from this spacecraft to provide accurate knowledge regarding Himalayan ice formation and melting, cyclones formation near Indian coastal line, Greenland ice melting, etc,” ISRO said.

This process of receiving back-scattered signal is carried out while conically scanning or rotating the antenna along with the motion of the satellite giving a swath of 1,400 km.

The collected data is processed on-board to generate estimate of back-scattered power/signals and stored on a data recorder.This recorded data is then transmitted to ground station which is converted into wind vectors for the global user.

These wind vectors will help meteorologists in accurately predict the cyclone formation, its movement and estimated landfall.It may be recalled that Ocean wind vectors data helped in accurately predicting cyclone ‘Phailin’ in the Odisha coast in 2013, which helped in mitigation and saving of mankind and livestock.
