ACM WG Focus will be on 2 Supersites

• S1 has all of the required measurements
• S2 is close
• Request that a microwave radiometer (perhaps from
  UK or from Potenza) be located there
• Needs a cloud radar perhaps the UHH radar
  currently listed at the S3 site?
• Request that one of the UK Doppler lidars be
  placed at S2, the other on the Hornisgrinde
• Possibility of in-situ aerosol observations (esp
  CCN spectra) on the Hornisgride?
• Chemical composition measurements from UK
  considered important
• BAE-146 in-situ observations will be critical
• Flight pattern includes legs in the aerosol layer
  below cloud and multiple penetrations at
  different altitudes in the cloud
• Would like to have one ACM representative in the
  operations center for daily planning
