CHENNAI: As meteorologists observed a trough of low in the southern http://timesofindia.indiatimes.com/topic/Indian-Ocean”>Indian Ocean more than a week ago, five Indian satellites kept a constant eye on the system as it brewed into cyclone Fani.
As it developed into an “extremely severe cyclone”, the satellites launched by Isro sent data every 15 minutes to the ground station, helping track and forecast its movement and save hundreds of lives.
According to IMD, data from satellites Insat-3D, Insat-3DR, Scatsat-1, Oceansat-2 and Megha Tropiques was used to study the intensity, location and cloud cover around Fani. There was a cloud cover around the eye of the storm up to 1000km radius, though the rain clouds were only up to a radius of 100 to 200km. The rest were at a height of around 10,000feet.
