In late December 2022 and for most of January 2023 an atmospheric river (yellow plume over North Pacific Ocean) transported vast amount of water vapor from the tropical belt across Pacific up to west coast of North America, leading to record precipitations in California especially when it combined with the extreme event that developed on […]


Floods in Pakistan August 2022

Torrential monsoon rains and record glacier melting caused by a severe heat wave triggered devastating flooding in Pakistan. The peak of flooding was reached in early September, leaving 8000 km2 of the Sindh province under several meters of water across a 100 km distance. Over hundreds of kilometers, the Indus River became a gigantic river over […]


Wildfires in southwest France July 2022

The VIIRS sensor on board NASA/NOAA’s Suomi-NPP satellite captured this true-color image showing wildfires raging in southwest France in La Teste-de-Buch (left) and Landiras (right) on July 18, 2022 at 13:30 UTC. Close-ups show those 2 wildfires observed by the MSI sensor on board Copernicus’s Sentinel-2B satellite on July 17, 2022 at 11:09 UTC. Source: […]


A zoo in a cloudy sky

Look !! A bunny !  Remember when as a kid you would star at the sky finding rabbit shaped clouds and all sorts of other fluffy animals … Well that’s exactly what Camilla, one of our recent visitor from a neighbour college did. As she was browsing through satellite imagery on Worldview, Camilla ran into […]


Von Karman vortices off the Canary Islands

This remarkable phenomenon easily visible from satellite and called Von Karman vortices, occurs under particular conditions of wind and terrain relief. It is commonly observed downwind of the Canary Islands when sustained trade winds blow through the islands (from the northeast to the southwest). The island relief disrupts the air flow, deflecting it around on each side. As the air flow passes […]

Brighter gray shades indicate greater water vapor content (including clouds when relative humidity reaches 100%). Dark gray shades indicate dry air. Source:EUMETSAT/AERIS/SATMOS/ICARE Déplacer […]


Saharan dust gushes over Europe March 15, 2022

An exceptional amount of dust particles lifted by strong winds in the Sahara desert in Algeria traveled north across the Mediterranean Sea and reached Western Europe from March 15 through 18, 2022. Spain and France received especially high concentrations of dust, which brought brown-orange skies and strongly degraded air quality. The plume continued to travel […]


Tropical cyclones Batsirai and Emnati hit Madagascar – February 2022

The 2021–2022 Southwest Indian Ocean cyclone season is currently in full swing. Southern Africa and nearby islands of Madagascar, Reunion and Mauritius are confronted with a very intense and deadly cyclone season, causing widespread damage and destruction, and displacing hundreds of thousands of people.The island of Madagascar was especially impacted as 4 of the first […]


Eruption of Hunga Tonga volcano in the South Pacific ocean January 15, 2022

This true-color image acquired by the Advanced Himawari Imager (AHI) on board Himawari (JMA) shows the thick round “umbrella” plume of ash rising high in the atmosphere and flattening upon reaching the tropopause. The coastlines of neighboring islands are drawn in the image, showing Tongatapu (the main island of the archipelago and host of the […]
