Similarly to the ICCP, the Workshop Lidar Measurements in Latin America had to be postponed by one year due to Covid19, but in the end only could be held virtually. Organized by Boris Barja at UMAG, this would have been the perfect opportunity for a reunion at Punta Areans.

However, quite a few studies are related to DACAPO-PESO:

  • Radenz et al.: Aerosol optical properties during DACAPO-PESO and comparison to in-situ observations
  • Ohneiser et al.: Long-term lidar measurements of Australian wildfire smoke layer in the stratosphere over southern South America in 2020-2021: Potential influence on ozone reduction?
  • Seifert et al.: Theoretically derived thresholds for the detectability of ice crystals by polarization lidar
  • Jimenez et al.: Aerosol-cloud interactions assessed with a dual-field-of-view polarization lidar: contrast between pristine and polluted conditions
  • Barja et al.: Cloud and aerosols observation in Punta Arenas, Chile

The abstracts can be found in the conference booklet: pdf


While the measurements were still ongoing at Punta Arenas, we had a small 2-afternoon hybrid workshop for discussing current results and future collaborations. Meanwhile quite a few people are looking at the data for various projects.

To get an overview, I tried to sort them into the aerosol-cloud-dynamics-precipitation interaction chart.


During the workshop we were a bit surprised ourself, how many processes are already under investigation, covering aerosol in-situ characterization, cloud droplet formation, droplet freezing, cloud-dynamics interaction, Aeolus satellite cal/val, riming/aggregation, and their impact on surface precipitation.

So far, 6 peer-reviewed articles based on the DACAPO-PESO observations were published. Thee more are currently finalized. During the discussion on the second afternoon we identified half-a-dozen topics for further investigation.


In case you plan to attend the International Conference on Clouds and Precipitation 2021, a few talks also deal with DACAPO-PESO data

  • Teisseire et al.: Attribution of riming and aggregation to the evolution of hydrometeor shape and orientation in mixed-phase clouds with SLDR-mode scanning cloud radar
  • Radenz et al.: High frequency of ice formation stratiform clouds revisiting effects of turbulence, coupling and instrument sensitivity
  • Wex et al.: Ice Nucleating Particles in Southern Chile and their connection to cloud
