Atmospheric Correction Inter-comparison eXercise (ACIX-III) and Cloud Masking Inter-comparison eXercise (CMIX-II)

We would like to invite you to participate to the next Atmospheric Correction Inter-comparison eXercise (ACIX-III) and/or Cloud Masking Inter-comparison eXercise (CMIX-II).

The exercises are collaborative activities of ESA and NASA that initiated in 2016 in the frame of CEOS WGCV. ACIX has been already implemented twice on multispectral Copernicus Sentinel-2 and Landsat 8 imagery. More information on the latest analysis and the results can be found in the dedicated web pages for the -Land and -Aqua focused part of the exercise. In parallel with ACIXs, CMIX ran over specific areas for which there were reference data available. Similarly to ACIXs, the focus of the first CMIX was on Sentinel-2 (EC/ESA) and Landsat 8 (NASA/USGS) imagery. More information on the first CMIX implementation can be found on https://calvalportal.ceos.org/cmix.

The 1st WS of ACIX-III and CMIX-II will be held in ESA/ESRIN (Frascati, Italy) on 20-21 June 2022.

Participation To ACIXs And CMIX Is Open To All The Scientists Who:

1. are the original developers of the atmospheric correction and/or cloud-masking processor to be inter-compared,
2. are authorized by the original developer to run the AC/CM processor on his/her behalf,
3. agree on submitting the AC/CM processing results within the required constraints (deadline, format, etc.).

For more information on the exercises and the registration for participation, you can find here.

Many thanks,

the ACIX/CMIX organisation committee
