#Europe’s new #Sentinel-4 satellite has delivered its first data, mapping #air #pollutants like nitrogen dioxide and ozone from #geostationary orbit.

We pointed a commercial-off-the-shelf #satellite dish at the sky and carried out the most comprehensive public study to date of #geostationary satellite #communication. A shockingly large amount of sensitive traffic is being broadcast #unencrypted […]
The #ViaSat3 project continues its mission to redefine global connectivity. With the second satellite delivered by #Boeing at the end of September, #Viasat moves closer to building one of the most advanced #broadband #geostationary #satellite #constellations ever created.

A great use of satellite platforms: ML applied to #geostationary native radiance observations (GOES and TEMPO) with High res model outputs to derive surface PM2.5

Contrary to sounding 'over Europe', MTG-S1 is positioned at 0°N 0°E. This strategic spot allows it to monitor weather systems forming over the Atlantic that frequently impact European weather, crucial for advanced forecasting. #Geostationary 2/5
Chinese scientists have reportedly achieved a 1 Gigabit per second (Gbps) data #transmission from a #geostationary #satellite to #Earth using just a 2-watt laser

#Volcanic SO₂ plume from #Kanlaon #volcano captured and entrained by Super Typhoon #Man-yi (#Pepito) during its passage through the #Philippines. Data from the #geostationary GK-2B GEMS instrument.
Satellite data from @CopernicusEU #Sentinel5P #TROPOMI show a band of #volcanic SO₂ advancing over the NW #UK and #Ireland on Aug 24, behind a cold front. Observations of SO₂ over Europe are set to improve (-> hourly) with the upcoming launch of the #geostationary #Sentinel4.
The largest #eruption on record of #Kanlaon/#Canlaon #volcano (#Philippines) on June 3 produced an upper tropospheric SO₂ cloud (~0.05 Tg SO₂), seen here from #geostationary orbit by #SouthKorea's UV #GK2B #GEMS sensor.

SO₂ emissions from the April 16 #eruption of #Ruang #volcano (#Indonesia) measured with hourly cadence by #SouthKorea's #geostationary UV GK-2B #GEMS sensor. Relatively low SO₂ amounts detected so far. @PVMBG_ @id_magma @andrewcraigtupp
The polar-orbiting UV satellites missed the start of the eruption, late yesterday afternoon, when lava effusion rates (and hence SO₂ emissions) were higher. Future #geostationary UV SO₂ data from #Sentinel4 on MTG-S should allow SO₂ detection both earlier & later in the day.
Great to see the new #geostationary UV #GK2B #GEMS hourly SO₂ data presented at #AGU22. This animation shows SO₂ degassing at #Taal #volcano (#Philippines) detected by GEMS in October 2022. Potential game-changer for volcanic gas monitoring in E. Asia. @phivolcs_dost @nababaha
