Objectives:
develop an improved cloud parameterization in HARMONIE
test and evaluate this on the European scale with MSG and Cloudnet observational products for a period of at least one year.

4. the Cloudnet project (EU FP5 funded, 2001-2005)
Main objective:
Continuous evaluation of cloud profiles in
operational models using ground-based observations to quantify and improve the model performance
Remote Sensing Systems:
cloudradar, lidar/ceilometer, and microwave radiometer
Derived Parameters:
profiles of cloud fraction, liquid and ice water content
(overview article: BAMS, A.J. Illingworth et al, June 2007)

5. Cloudnet started with 3 stations: Cabauw, Chilbolton and Palaiseau…
… but expanded in time to many more
e.g. Lindenberg and ARM sites
seven operational weather models
were evaluated (including RACMO)
In 2011 EUSAAR, Cloudnet and EARLINET joined in the ACTRIS project
(Aerosols, Clouds and Trace gases Research infraStructure)

6. Towards an European Infrastructure:
2001 – 2005: Cloudnet (EU FP5)
2006 – 2010: cloudnet continued on voluntary base (no EU funding)
2010 – 2015: ACTRIS (EU FP7)
2015 – 2019: ACTRIS-2 (EU H2020)
2016: ACTRIS on ESFRI Roadmap
2016 – 2019: ACTRIS-Preparatory Phase Project (EU H2020)
2020 – 2040: ACTRIS ERIC (European Research Infrastructure Consortium)

16. Conclusion Cloudnet processing chain is a versatile tool for
evaluation of model performance with respect to clouds (both water & ice)
Outlook for CRIME:
assess sensitivity of results for
- ceilometer selection (LD40 vs. CHM15K)
- system calibration (cloudradar, radiometer)
- time averaging and processing thresholds
process 2 years of archived HARMONIE model data (cy36, cy38)
to gain experience with evaluation
with Cloudnet processing chain
