18. Mobile Aerosol Raman Lidar Requirements at the site  Save place for two 20-feet containers  MARL (AWI 002) + accompanying container (AWI 011) -spare parts -tools -additional PCs data storage online data evaluation internet router -office space -work shop  solid ground (supporting a 10 t container)  guarded

19. Mobile Aerosol Raman Lidar Requirements at the site  The power supply  German (Dutch?) standard 3phase high current supply: - 5-line cable: 3Phase+Neutral+Ground (no triangle connection) - 230 V, 400 V P-P, - 32A, 50Hz, 15kW  another line (5 kW) for AWI 011  stability of the net?  UPS?

20. Mobile Aerosol Raman Lidar Requirements at the site  Other Infrastructure  Access to -Internet -Telephone -Fax  indoor space (not compulsory when AWI 011 is available)

21. Mobile Aerosol Raman Lidar Things to discuss: infrastructure  container site - Distance to power supply - container side by side? - preparation of the ground  stability of power supply  internet access: -one fixed IP address -LAN (10 - 100 Mbit?) -and/or ISDN  Access to site: day and night ? - Possibility to sleep over - Food supply?  Accommodation?  Transportation (rental car? bycicle?)

22. Mobile Aerosol Raman Lidar Things to discuss: contribute to WP5  Student practica, working with the instrument  lecture at ADeK

23. Mobile Aerosol Raman Lidar Things to discuss: authorities  customs - formalities -dead lines -fees -limitations (time period)  permission for laser (air control, military ?)  declaration of dangerous goods - small amounts of acetone, methanol, cooling agents, N 2 - - available on site?  costs -infrastructure (internet, electricity, etc.)

24. Mobile Aerosol Raman Lidar Things to discuss: schedule  MARL available from 7/04 to 12/04  campaign in dry period Sept - Nov 04  desirable to have radiosondes, in particular water vapor (snow white.  persons involved -setup: Ingo Beninga, Wilfried Ruhe (partly engaged from Oct-Feb), Franz Immler -measurement: David Kaiser, Franz Immler, IB, WR -SETUP: -Campaign:
