Climate and Seasonal Forecasting

Web Content Image

Satellites are a vital tool for monitoring the climate and how it can affect weather seasons, leading to phenomena such as the "El Nino". This is useful for forecasting potential weather systems.

Copernicus Sentinel-3's OLCI and SLSTR instruments provide data for climate modelling and impact studies. The ALT instument supports Climate & Seasonal Forecasting, and the mission also undertaks monitoring of river and lake levels, and contributes to flood monitoring studies. More on Sentinel-3's marine monitoring applications can be found in the OLCI and SLSTR User Guides.

Thematic Results

Each year, about a quarter of the carbon dioxide we release into the atmosphere ends up in the ocean, but how it happens is still not fully understood. The Sentinel-3A satellite is poised to play an important role in shedding new light on this exchange.

Mesoscale marine atmospheric boundary layer (MABL) phenomena are frequently observed by satellite sensors. They appear either as organised cloud patterns in visible-infrared satellite images or as coherent patterns on the sea surface in microwave synthetic aperture radar (SAR) images.

ESA joined international delegates in Doha, Qatar, to discuss how satellite observations show our planet's most sensitive areas reacting to climate change - and how this information is useful to the people living there.

Scientists have gathered in the 'floating city' this week to talk about radar altimetry - measuring the heights of the global sea surface, freshwater bodies, land and ice using spaceborne sensors.
