First WG2 aerosol subgroup-ALC retrievals: impressions

The first meeting  of the WG2 subgroup on aerosol and ALC retrievals took place on the 15th December 2021.

The meeting was structured as follows:

  • 5 minutes: Introduction & welcome (Joelle Buxmann)
  • 15 minutes: Update on E-PROFILE ALC retrieval activities (Rolf Rüfenacht and Augustin Mortier)
  • 10 minutes: Aerosol retrievals within Alicenet. (Henri Diemoz)
  • 10 minutes: SCC and ALC activities of ACTRIS-CARS (Ina Mattis)
  • 10 minutes: Retrievals made for miniMPLs in the ACTRIS-France framework  (AUBERT Sylvain)

10 minutes: discussion-all


The meeting provided a good platform for discussing profile retrievals from ALC. Some common problems and issues came up during the discussion of the individual presentations, such as seasonality of the calibration constant and how cloud screening prior to the retrieval is performed. The calibration issue is also being discussed in a smaller focused subgroup within WG3/4 (see meeting notes from 3. December 2021).
