Phenology: In Vaira, no collectable grass leaf left in main areas, only few under tree. In Tonzi, small spread-leaf grass still green, and LAI samples were collected.

Summary

• Flux system worked well, and data were downloaded.
• Li-7500 was swapped in Tower site.
• Soil moisture Probes were not measured because of instrument conflict with Jorge.

Tasks

1. check Flux systems, swap Li-7500 in Tower, download data
2. grass and oak leaf samples in Tonzi
3. Alex’s samples
4. Spectrum measurements
5. dendrometer
