What is SWOT?

About:

• The launched satellite is named as SWOT (Surface Water and Ocean Topography).
• The advanced radar satellite is designed to give an unprecedented view of the life covering 70% of the planet, shedding new light on the mechanics and consequences of climate change.
• The satellite incorporates advanced microwave radar technology which will collect surface measurements of oceans, lakes, reservoirs and rivers in high-definition details.

Partners:

• SWOT is being jointly developed by NASA and Centre National D'Etudes Spatiales (CNES) with contributions from the Canadian Space Agency (CSA) and United Kingdom Space Agency.

Advantages of the satellite:

• It sweeps of the planet at least twice every 21 days, will enhance Ocean circulation models bolster weather and climate forecasts and aid in managing scarce freshwater supplies in drought-stricken regions.
• It is equipped to observe the entire length of nearly all rivers wider than 330 feet and more than 1 million lakes and reservoirs larger than 5 acres.
• It will precisely measure fine differences in surface elevations around smaller currents and eddies, where much the oceans’ drawdown of heat and carbon is believed to occur.
