As physical events are not permitted in May 2021, the format of an online workshop has been selected. This workshop is dedicated to the introduction of EarthCARE validation proposals that have been accepted in the period after the previous workshop, and to the discussion of validation methods and validation protocols in the domains addressed by the EarthCARE mission. To foster intense interactivity during the working sessions and in particular the splinter sessions, this online workshop will not be a an online public event as this format would be limited to presentations with questions and answers. Because a higher level of interactivity is required to meet the workshop objectives, participation is reserved to the Principal Investigators (PI) of the EarthCARE ESA AO, their Co-Investigators (Co-I), and the EarthCARE Data Product Algorithm Developers and EarthCARE instrument experts, and the members of the EarthCARE Mission Advisory Group. ESA delegates and the EarthCARE Principal Investigators of the JAXA Research Announcement are welcome to attend, and scientists from other missions will also be invited.

More information is available in the section of the portal that is reserved to the EarthCARE Validation Team Members (PIs and Co-Is)
