The ESA Cloud_cci Project  [2011-06-09]

The ultimate objective of Cloud CCI is to provide long-term coherent cloud property data sets exploiting the synergic capabilities of different Earth observation missions allowing for improved accuracies and enhanced temporal and spatial sampling better than those provided by the single sources.

This project seeks to utilize the increasing  potential of the synergic capabilities of past,  existing and upcoming European and US  missions in order to meet the increasing  needs for coherent long-term cloud property datasets required by the scientific community.

Cloud_cci User Workshop  [2018-05-09]

The Cloud_cci User Workshop was held on 15 and 16 of November 2017 at DWD facilities in Hamburg, Germany with 24 participants. Main topics addressed during the workshop were:

  • Reviewing core achievements of Cloud_cci (Algorithms and datasets)
  • Applications for model evaluations
  • General climate analysis and characterization
  • Applicability of cloud droplet number concentration and its retrieval
  • Aerosol-Cloud interactions
  • Practical applications
  • Introducing the CCI toolbox using the example of Cloud_cci data

The workshop program is available here. The presentations given at the workshop can be downloaded here.

The presentations given indicated the wide range of application that are done/feasible using Cloud_cci data. This range will widen a lot when radiation properties become available (colocated to the cloud properties) in v3.0 dataset. The feedback by the participants was very positive. Several side discussions tackled the v3.0 datasets, corresponding improvements compared to v2.0, their content and availability. A prototype version of the AVHRR-PM v3.0 had been made available to selected users. Side discussion during the workshop also included status updates and clarifying further work on remaining tasks in the Cloud_cci project, e.g. (simplistic/full) Cloud_cci simulator, last CC4CL updates before generation of AVHRR-AM/PM and ATSR2-AATSR v3.0 datasets.

Release of Cloud_cci version 2.0 datasets  [2018-01-15]

The Cloud_cci Project team is pleased to annouce the release of the version 2.0 of the Cloud_cci datasets. Key scientific characteristics of the datasets are summarized in Stengel et al. (2017).

For each dataset a digital object identifier has been issued:
Cloud_cci AVHRR-AM:
Cloud_cci AVHRR-PM:
Cloud_cci MODIS-Terra:
Cloud_cci MODIS-Aqua:
Cloud_cci ATSR2-AATSR:
Cloud_cci MERIS+AATSR:
