Kerala floods: How Isro satellites are playing a key part in saving lives

KerelaFloods - Even as the unprecedented floods and landslides have devastated most parts of Kerala in the last fortnight, technologically the most helpful support the authorities are getting in handling the situation was updates from Indian Space Research Organisation (Isro) and its various satellites which kept their eyes open up from the atmosphere.

A set of remote sensing satellites and radar satellites has been taking pictures of various aspects of the situation in the flood-hit state from a distance of 400-800 kilometres from the Earth and sending it back with supportive data, which once crunched, helped the experts to predict the level of rains till then, what to expect in the next few hours and even about the situation in the forests and the water reservoirs.

For instance, ResourceSat-2, launched on April 20, 2011, has proved to be helpful in taking pictures on the forestry and normal terrain and how the water bodies are while ScatSat-1 can track the wind, how it flows over the sea and over the land which helps to forecast the weather. Insat 3DR, another satellite together with others can communicate how clouds are positioned and with the help of ScatSat-1, experts can come to a conclusion on how fast they are moving considering the wind speed. Insat satellites, which are geostationary, would send data in every half an hour from the atmosphere, which can give an update to the ground station.
