Notas do Editor
- Wireless soil moisture sensor network (SoilNet) in a forest stand with 150 nodes (ca. 900 sensors) Installation is ongoing also for a grassland stand with 150 nodes
- Campaign data from 27th May 2008 Simultaneous flight of PLMR and E-SAR Campaign ongoing now and at the end of May with PLMR2 and F-SAR PLMR2 is owned by the Agrosphere Institute
