IRR Windprofiler/RASS Surface/tower
measurements Total Sky Imager
Video network IRR, CT12, LD40

• RADIOMETER
• frequent acquisition interrupt spring/summer
  2002
• (due to blocked air-filter)
• bias in LWP need correction with clear-air
  episodes
• rainflag not set (autumn 2001 summer 2002 ?)
• maintenance in November 2002
