3. ScaleX campaign
Climate change impact on local and regionalscales in different landscapes:
→ water and energy budget
→ trace gas emission
· long term measurements· intensive measurements · model validation on different scales

5. Conclusion and outlook
· Flying wing / Apogee - UAS:
· Easy setup (thanks to PPRZ/ENAC) & handling,· up to 1000m AGL· ascent frequency 1/2h, flight times >50 min, day & night· dense in-situ measurement profiles, reasonable quality· high frequency UAS displacement as turbulencev proxy
ScaleX 2016 (focus on sensors):· barometer available, all UAS with Pt1000· faster response time for humidity sensors (P14 rapid?)· use flight recorder imu measurements for turbulence· field calibration between different UAS· systematic comparison with other instruments· model validation (WRF & METRAS)
