L9/TIRS processing added to ACOLITE/TACT! Here a 2021-11-08 image of the Mediterranean side of the Suez Canal (at Port Said and Port Fuad), and the brackish Lake Manzala. L9/OLI derived RGB and water turbidity. Some along track striping is visible in the TIRS data.

New ACOLITE binaries are available! Now includes support for Landsat 9 and SuperDove data! Here a 2022-01-17 L9/OLI image of Gulf Coro, south of the Paraguaná peninsula in Venezuela, with RGB, turbidity, and red band Kd outputs. Check it out: odnature.naturalsciences.be/remsem/acolite…

ACOLITE Docker images at hub.docker.com/r/acolite/acol… have also been updated to the latest version! Easily run DSF and TACT on your imagery using Docker. Here the 2021-11-09 L9/OLI and TIRS image of the Yangtze river and lake Taihu as processed with ACOLITE Docker!

Pansharpening of Landsat 7/8/9 data for visualisation was added to the ACOLITE Github code, and will be available in the next binary release! Here a surface level reflectance RGB image from L9/OLI of Oostende, Belgium at 30 metres and at 15 metres pixel size after pansharpening.

Landsat 8 image of the Antarctic Belgica mountains before (30 metres, left) and after (15 metres, right) pansharpening now integrated in ACOLITE GitHub code! Mounts Perov (top) and Lahaye, Van Mieghem, and Victor (bottom) at around 72.6°S and 31.1°E.

An artificial elliptical island under construction by Poland in the Vistula Lagoon, tentatively named Wyspa Estyjska / Aestian Island. Imaged here by Sentinel-2B on 2022-07-19. The strong red edge peak indicates these are floating scums in the lagoon surrounding the island.

ACOLITE/TACT near-realtime processing using GDAS1 forecast profiles! For scenes older than 90 days the default ERA5 reanalysis is recommended. Here the Nelson and Hayes rivers bringing sediments and warm water into Hudson Bay as imaged by L8 and L9 on 2022-07-12 and 2022-07-13.

Added ASTER Global Emissivity Dataset as option to ACOLITE/TACT for better surface temperature retrievals over land. Here a comparison of Landsat 8 TACT outputs using unity emissivity and GED emissivity for La Serena, Chile. GDAS1 atmospheric profiles for NRT processing.

Great news after the summer break! What are the performances of PRISMA Satellite Level 2D and ACOLITE derived water reflectance over two optically diverse inland and coastal sites? Read here 👇 authors.elsevier.com/a/1fcEx3I9x1j9…

In the Southern North Sea, PANTHYR autonomous hyperspectral radiometer is used to monitor blooms of Phaeocystis globosa, an algae with negative environmental impacts. Performance of future hyperspectral satellites could also be simulated. More info here : sciencedirect.com/science/articl…

New ACOLITE release available at github.com/acolite/acolit… This release fixes some issues with OLCI processing and includes EUMETSAT TOA gains. Here an example RGB composite of top-of-atmosphere and water reflectances over the Gironde estuary and French Atlantic coast.

HYPERNETS Science Conference on optical radiometry and satellite validation SAVE THE DATE - 21-23 March 2023 , Brussels, Belgium

More data coming! At the request of the @RBINSmuseum, European Space Agency temporarily increased the frequency of Copernicus EU #Sentinel2 B acquisitions collected over the Princess Elisabeth Antarctica, a Belgian Antarctic research station situated in the Sør Rondane mountains in Antarctica.

Also very interesting: International Polar Foundation is supporting cal/val activities taking place at the @AntarcticBaseduring the #Sentinel2 acquisition campaign. The Princess Elisabeth Antarctica was chosen as a HYPSTAR validation site.
