Did you know Copernicus Sentinel-3 SLSTR visible & NIR channels can be used to create false colour images such as this one of iceberg A23a, from 6 Feb. Later this year we will release new sea ice surface temperature products from SLSTR www.eumetsat.int/S3-SLSTR-SIST #remotesensing #earthobservation
Sea-ice surface temperature retrieval & validation for SLSTR
Developing a sea-ice and marginal ice zone temperature retrieval and prototype processor for SLSTR.

🔴⚠️🌋 #Iceland. The new eruption keeps feeding the lava flow that is moving at lower speed if compared with the peak of last night. The lava has already gone farther than 4km in W. direction and covers an area of about 7km2. Here the latest #Sentinel3 SWIR view by #SLSTR bands showing the lava flows

Different wavelengths, different insights: Remote sensing inputs like land surface temp, soil moisture, and freeze/thaw each reveal unique constraints on boreal productivity—combining them improves estimates. #GPP

From @oceandatalab.bsky.social Ocean Virtual Lab (OVL) you can examine the temperatures as seen by #Copernicus #Sentinel3 #SLSTR radiometer - in this instance from the thermal 12 micron band.

22C in the eye. Cooling rapidly up wall.

ooooof

(more intel from @CRUDEOIL231 on the bad place, comment in alt)
I looked up Sentinel-3 satellite imagery for cross-validation. ESA also runs the Sentinel-3. While Sentinel-2 is essentially just a single high-res multispectral optical payload (MSI), Sentinel-3 packs a whole suite of sensors; optical (OLCI), precision thermal radiometry (SLSTR), and radar altimetry (SRAL). The spatial resolution gets chopped hard versus Sentinel-2 and the swath is huge, but it's more than sharp enough to flag severe thermal anomalies across open desert scrub. Breaking down the frames. OLCI is the familiar optical sensor. Pulled the OLCI L1B baseline imagery and ran the Highlight Optimized Natural Color processing layer to keep the blown out white pixels from clipping over high-albedo terrain. Then you have SLSTR L1B—provides the baseline thermal infrared and optical observations. It is used to verify sea/land surface radiant temperatures and active fire pixels. I selected the F1 Brightness Temperature layer, a dedicated mid-wave/thermal infrared band designed specifically for active fires (such as wildfires and gas flares). The delta between yesterday's pass and today is night and day. Again: zero interest in feeding the toxic bull/bear crossfire. Just sharing OSINT observations through open source feeds.
