Minimize AVHRR 1-km (LAC) Expert Meeting

The AVHRR 1-km (LAC) Expert Meeting was hosted by the German Remote Sensing Data Center (DLR-DFD) at DLR-Oberpfaffenhoffen, Germany on 20-21 April 2015. Twenty-two experts from Europe and the United States representing the AVHRR, the calibration, the remote sensing, and user communities participated in the meeting organised by ESA/SPPA and DLR-DFD, to discuss the challenges and priorities of future reprocessings of the European archives of AVHRR 1-km data. The minutes of the meeting can be here.
