EUFAR/ ICCP/ IUGG/ IAMAS Expert Workshop on Processing of Cloud Particle Measurements

Date the workshop: 7 - 9 July 2017 (prior to ICARE2017)

Place of the Workshop: DLR, Oberpfaffenhofen, Germany


  • Darrel Baumgardner (DMT)
  • Greg Mc Farquhar (University of Illinois)
  • Local organisation: Christiane Voigt (DLR, EUFAR)

Recent analysis showed differences in cloud data sets from airborne instruments caused by different data analysis methods. Thus it is the scope of the workshop to discuss, optimise and harmonise cloud data analysis and correction methods from cloud imagers operated on research aircraft within the international cloud community. The workshop will also focus on knowledge transfer and training for students and early career scientists who will be working with cloud measurements carried out using a broad array of sensors.

This workshop is a follow-up of the 2014 Data Analysis Workshop that was convened in Boston prior to the American Meteorological Society (AMS) cloud physics conference and the 2016 software workshop that met prior to the International Conference on Clouds and Precipitation (ICCP) held in Manchester in July (sponsored by ICCP, EUFAR and IAMAS/IUGG). These two workshops have set the stage for the 2017 workshop, which will have a strong component of knowledge transfer. The workshop seeks to provide hands-on training on the software packages that are most widely used by the scientific community to analyse ground-based, airborne, and in situ cloud measurements. By the end of the workshop, participants will be expected to be moderately proficient in manipulating, analysing and graphing data.

The 2016 EUFAR/ICCP workshop on cloud measurements confirmed that there is a lack of consistency in correction/analysis algorithms applied to cloud measurements and their implementation. There is a need to bring consensus among the community, in order to discuss “best practices” in processing data and reporting results. This is the overarching motivation for this workshop. Best practices will be discussed based on the evaluation of new observations in liquid, mixed phase and ice clouds.


The objectives of this meeting are the following

  • Hands-on training on software packages from cloud probes
  • Reach consensus on optimum practices for cloud probe data algorithms, including aspects of their implementation and documentation, whenever possible
  • Identify aspects of algorithms that cannot be optimised in general and that must be set for individual probes or individual datasets
  • Monitor the progress in cloud data evaluation and inter-comparison

The workshop is planned in connection with EUFAR’s 2nd International Conference on Airborne Research for the Environment (ICARE 2017) to be held at DLR in Oberpfaffenhofen, from 10 to 13 July 2017.
