Sentinel-2 data is online for quite a while and now we would like to have a deeper look into how to get the L1C data. According to the tiling scheme discussed in the previous post, there are about 22,000 tiles covering the land masses as well as smaller seas.One full coverage of the Earth will consume storage size of about 3 Terabytes. Sentinel-2 L2A imagery has been processed with ESA's Sen2Cor atmospheric processor. Sen2Cor is top of the line atmospheric processor, so if you have the imagery in L2A you can be assured that the quality will be very good. With this being said, L2A imagery has a shorter availability. the iCOR atmospheric correction algorithm, available through the ESA Sentinel Application Platform (SNAP), to the Sentinel-2 image. The processing parameters depend on the surface to be corrected.

Those are surface reflectance (SREF), standardized surface reflectance (STDSREF), Sentinel-2 atmospheric correction (S2AC), image correction for atmospheric effects (iCOR), dark object subtraction (DOS) and top of the atmosphere (TOA) reflectance without any atmospheric correction.

Satellite remote sensing aerosol monitoring products are readily available but limited to regional and global scales due to low spatial resolutions making them unsuitable for city-level monitoring. Freely available satellite images such as Sentinel -2 at relatively high spatial (10m) and temporal (5 days) resolutions offer the chance to map aerosol distribution at local scales. As explained by @kraftek, Sen2Cor version 2.8.0 contains new features and improvements respect to Sen2Cor v2.5.5 but it doesn’t support some old products.For this, we have decided to support both sen2cor versions by two different plugins in SNAP, so you can execute both. For that, two new plugins have been created and are available in the update center: SEN2COR280 and SEN2COR255.

For the atmospheric correction of the data EPA and VITO will use iCOR , the atmospheric correction software . iCOR can be used to process a variety of airborne and The iCOR atmospheric correction was already available for Landsat-8 OLI and Sentinel-2 MSI. Already more than 700 registered users are now able to use the same atmospheric correction for Sentinel-2, Landsat-8 and Sentinel-3. Read more to discover how it works and what’s in it for you. Multispectral remote sensing may be a powerful tool for areal retrieval of biogeophysical parameters in the Arctic sea ice.

Those are surface reflectance (SREF), standardized surface reflectance (STDSREF), Sentinel-2 atmospheric correction (S2AC), image correction for atmospheric effects (iCOR), dark object subtraction (DOS) and top of the atmosphere (TOA) reflectance without any atmospheric correction. iCOR is configurable for any optical sensor and can be used over multiple targets. • Inland waters • Coastal waters • Transitional waters • Land • Sentinel-2 • Landsat-8 • Sentinel-3 • Airborne hyperspectral • MERIS • PROBA-V → configurable for the sensor of your choice iCOR (by VITO NV, Belgium) After releasing iCOR for the atmospheric correction of Sentinel-2 and Landsat-8 data, thanks to the iCOR4S3 project, the iCOR software is now available for atmospheric correction of Sentinel-3 OLCI. Integration of Sentinel-2 and Landsat-8 imagery is a key factor to provide earth observation data at a global scale with higher temporal resolution. The MultiSpectral Instrument on board the Sentinel-2 (S-2) satellites of the European Space Agency offers new possibilities for Arctic research; S-2A and S-2B provide 13 spectral bands between 443 and 2202 nm and spatial resolutions between 10 and 60 m, which may enable the monitoring of large areas of Arctic sea ice. Esri's Sentinel Explorer app is a powerful tool for visualizing our planet and understanding how the Earth has changed over time.

The version for Sentinel-2 and Landsat-8 was made available to the broad user community through the ESA Sentinel Application Platform (SNAP). Sentinel-2 atmospheric correction (S2AC), image correction for atmospheric e ﬀ ects (iCOR), dark object subtraction (DOS) and top of the atmosphere (TOA) reﬂectance without any atmospheric SENTINEL-2, launched as part of the European Commission’s Copernicus program on June 23, 2015, was designed specifically to deliver a wealth of data and imagery. The satellite is equipped with an opto-electronic multispectral sensor for surveying with a sentinel-2 resolution of 10 to 60 m in the visible, near infrared (VNIR), and short-wave Sentinel-2 data calibration and validationVirtual Special Issue Acknowledgement The editors of this special issue would like to sincerely thank ESA’s S2 present (Ferran Gascon) and previous (Bianca Hoersch) mission managers and their support team (Valentina Boccia, Enrico Cadau, Rosario Iannone), the S2QWG members, the European Journal of Remote Sensing (Patrizia Rossi, Marco Gianinetto) and Introduction to iCOR and ACOLITE atmospheric correction for Landsat-8 and Sentinel-2.
