NHC calls it a hurricane, and that seems correct to me.

Cat 5 Hurricane Polo, seen 22nd Sept by the OLCI instrument aboard Sentinel-3B. Polo rapidly intensified and now has ferocious winds OLCI is designed to look at the Earth's oceans, seas and lakes - but thanks to a great design is also super useful for monitoring weather too @esa.int @eumetsat.int

Late on Monday night, @esa.int successfully launched FLEX and Sentinel-3C aboard an Avio VEGA-C rocket. Two really exciting missions, am super happy to see them in orbit and am looking forward to working with Sentinel-3C as we get it ready for operations. 😃

Simon Proud @simonsat.bsky.social · 08/09/2026

In six days, we will launch the FLEX and Sentinel-3C satellites! S3C will ensure we can provide high quality climate data and information to support distaster response into the next decade. Can't wait to see these two beautiful satellites in space 🚀 @esaearth.esa.int @eumetsat.int @ec.europa.eu

Drought conditions across Western Europe - the effects of our hot, dry, summer so far These two pics were taken by the Copernicus Sentinel-3 mission ~7 weeks apart. The effects of limited rainfall and hot, clear, weather are clearly visible: Much of Western Europe is looking desert-like from space.

Sentinel-2 and wildfires: These last few days, a devastating wildfire has been raging near Los Gallardos in Spain - sadly resulting in multiple deaths and significant destruction. This pic was taken on 10th July by Sentinel-2A, the scale of the fire clearly visible.

For those of you interested in our Sentinel-2 night imaging campaign, the data is now ready: freely and openly available! Details: sentinels.copernicus.eu/web/sentinel... Am hoping this data is useful to the EO community, and happy to hear your feedback! @esa.int @esaearth.esa.int @ec.europa.eu

Breathtaking! As a child I wanted to travel to the Moon...as an adult, my height worked against me and my travel plans - but I was hooked on space anyway! Delighted to see a joint American + European success on Artemis II! @esa.int supplying the service module. 💪🛰️

Dual use: If we like it or not, all civilian sats have defence-related uses. This video shows the Russian Arctic Metagaz LNG carrier exploding after reportedly being hit by Ukranian drones. It comes from @eumetsat.int's Meteosat-12, a weather satellite. Weather is civil, but we see so much more.

Earlier in Feb, Cyclone Gezani hit Mozambique, sadly resulting in fatalities anddamage to buildings Here, two Sentinel-2 pics show the impacts: Flooding inland, and a hugerunoff heading into the ocean. S2 is critical for disaster response - and we plan to improve its value for the next gen mission!

Fifty two thousand six hundred orbits around our wonderful little planet! Congrats Sentinel-3A! Later this year, younger brother S3C will be launched - ready to take over the operational optical imaging duties so that S3A can enjoy a well-deserved retirement 😀

We have some technical limits on this (thermal and electrical) so it's not possible to do systematic night acquisitions with the current generation unfortunately. For next gen, I aim to have some night capabilities - but not as frequent / comprehensive as the daytime imaging.

020

Simon Proud @simonsat.bsky.social · 19/01/2026

In December, we ran a campaign to switch the Sentinel-2A satellite on at night over some specific areas. The goal was to provide data to help me work out how useful night imaging capabilities would be for next gen Sentinel-2...and the results are wonderful! Read more: www.esa.int/Applications...

Small update to say that the mission performance centre are investigating this - will report back when I have any news :)

Kinda shocked at how the Netherlands copes with a little bit of snow. Every train cancelled, roads not clear, people "stocking up on supplies in case shops close". But, tbh, im glad to know its not just the UK that cant handle winter weather. I thought blighty was the exception 😂

Simon Proud @simonsat.bsky.social · 05/01/2026

Interesting, thanks. My municipality (Voorschoten) obviously sucks when it comes to snow machines 😂

010

Simon Proud @simonsat.bsky.social · 05/01/2026

Yes, exactly- this is my point. Cars prioritised and inadequate services for bikes and public transport. Is disappointing compared to other similar countries.

120

Simon Proud @simonsat.bsky.social · 05/01/2026

I must say I was disappointed! Expected the Dutch authorities to clear the cycle lanes, but they only cleared / gritted the car lanes - cycle lanes filled with slushy snow and ice.

The traditional end of year collab between @esa.int , @eumetsat.int, @wmo-global.bsky.social and me. I love making these pics...MTGsending back beautiful data as always! 😍 These four are 06UTC on: 19/12, 22/09, 21/06 and 20/03 Nice seeing how the sunlight moves around our planet during the year.

Simon Proud @simonsat.bsky.social · 17/12/2025

Yes indeed, which is why I'm confused! But it looks very much like an artefact related to the atmospheric correction and the scene geometry (most likely solar zenith angle). Maybe some numerical precision thing? Will be easier to tell when I see the data :)

100

Simon Proud @simonsat.bsky.social · 17/12/2025

@kosmi.bsky.social could you provide a link to the L2A scene on the brower, including whatever band division you did to highlight the artefacts? I will forward it to the data quality team and get their feedback.

110

Simon Proud @simonsat.bsky.social · 17/12/2025

I would say the opposite! :) My first guess would be that this is an artefact introduced by the atmospheric correction, most likely tie points in the lookup tables.

Simon Proud @simonsat.bsky.social · 10/11/2025

I do both of these things many times each week. It's not a problem.

Simon Proud @simonsat.bsky.social · 06/11/2025

Huge dust storms in Pakistan, seen by the @esa.int / @ec.europa.eu Sentinel-2B and Sentinel-3B satellites on 4th November. Neither satellite was designed to monitor dust plumes, so it's impressive how much information they give us about the detail and extent of these storms!

Along the N. Coast of Alaska, winter is closing in. These pics ages, from the Copernicus Sentinel-2 mission, were taken just two weeks apart. Heavy snowfall on land, and the beginnings of ice on sea. Soon, the sun will be too low and Sentinel-2 will stop acquiring images until Springtime.

081

Simon Proud @simonsat.bsky.social · 28/10/2025

Yeah, L1C also has the artifacts - caused by differing detector geometry. Only the L1b can fix it. very niche so doesn’t make too much difference though, just bugs the perfectionist in me! Really great that the imagery is on the browser so quickly. Will be super useful for the disaster response.

010

Simon Proud @simonsat.bsky.social · 28/10/2025

Looks good - but unfortunately the browser introduces some artefacts as it's using the L2 data.

Insane. This is Hurricane #Melissa seen right near landfall by the Copernicus / @esa.int Sentinel-2C satellite. It looks so beautiful, and it's hard to comprehend how much destruction a hurricane like this can cause. Best wishes to everyone in Jamaica.

Simon Proud @simonsat.bsky.social · 28/10/2025

17 hours of #Hurricane #Melissa seen from space compressed into 9 seconds. Weather sats are vital for monitoring and forecasting Hurricanes. Without them, our forecasts would be much worse - increasing the danger posed by these monsterous storms. Data: NOAA / GOES-19 Video: ESA / Simon Proud

It was great to be at @thalesaleniaspace.bsky.social last week to discuss the SIRIUS mission that is under consolidation as one of @esa.int's future SCOUT missions. SIRIUS will examine land surface temperature, with a focus on urban heat islands and unique data for evapotranspiration models.

Here are two images from the @esa.int / @ec.europa.eu Sentinel-2 mission showing the city of #Salalah in Southern Oman. One pic from June, before the rainy season, and one from this week, after the rains. The hills around the city transform into a lush green landscape!

An amazing change in the colour of the sea due to #Typhoon #Ragusa. The first pic was taken by the @esa_earth Sentinel-2 mission a few days before the typhoon, the second pic taken after the typhoon, just a few hours ago.

Delighted to see that the next Meteosat satellite will launch on a European rocket. MTG-I2 will complete the imaging constellation for Europe's next generation weather satellites, providing vital warnings for severe weather, wildfires, and more.

Congrats to my friends + colleagues across @esa.int , @eumetsat.int and @ec.europa.eu. MetOp-SG is exciting, a big leap forward for weather prediction. I think the key thing will be watching how scientists combine data from the different instruments to understand our planet. Lots of potential 😀

I saw that a new version of chatGPT has been released - gave it a quick try to write some simple python code...same garbage as the previous version. Now it's telling me that GPT is right and the python docs are wrong. At least for me, the AI bubble has well and truly popped 😆
