9 May 2011 - Launch of the model inter-comparison website
To make the inter-comparison plots available Roel Neggers has provided a website and plotting engine of our KNMI Parameterization Testbed (KPT). This website is a php-based platform that allows interactive plotting of all kind of datastreams against each other, making use of the open-source NCL plotting tool. The core and the layout is somewhat adapted, to better suit the typical needs of a model inter-comparison study. The website is hosted on a KNMI server.
As of today all submissions for both the ASTEX and composite transition cases are available on the website. For example, the website hosts an archive of prefabricated model inter-comparison plots, of the type expected from previous intercomparison studies within GCSS. These plots are often quite dense, due to the large number of participating models. They mainly serve to give an idea of the inter-model spread (which is still significant!), and to facilitate the identification of outliers. For focusing on single or fewer models it is suggested to use the interactive plotting module, available under "Interactive interface" on the menu page. Detailed visual instructions to this purpose are provided on the website. To the website .
9 May 2011 - Subset of data from climate models available
After an incredible amount of collective work and efforts over several years, global modeling centers now reach the stage where they can start distributing the outputs from their CMIP5 simulations. As of today, a subset of data from 9 climate models (including 3 EUCLIPSE models:
CNRM-CM5, HadGEM2-ES and IPSL-CM5A-LR) is available on the CMIP5 data portal . Many more models, experiments and outputs will be available in the next few weeks and months.

7 March 2011 - EUCLIPSE meeting coming up
The General Assembly of EUCLIPSE will be held jointly with the GCSS Boundary Layer Cloud Working Group and the EUCLIPSE project in at the MetOffice in Exeter during the week of 6th-10th June, 2011.
Please email, and by 31st March if you wish to attend, providing a title and short abstract if you wish to give a talk. Presentations on results and/or planned analysis related to CFMIP, EUCLIPSE and GCSS BLCWG activities, and more generally on work relevant to understanding, evaluating and improving the representation of cloud processes and cloud feedbacks in global models are welcome.
Thursday afternoon and Friday morning will be dedicated to EUCLIPSE planning, survey of the past year and other practical issues.
More information is available at CFMIP -> Meetings .
7 March 2011 - Broadcast "Cloudbusters"
As mentioned below (Februari 14th) a mini-documentary was made about EUCLIPSE in february. This documentary will be broadcasted by EURONEWS television, the Futuris magazine story, entitled : "The Cloudbusters" on 10th March at 18.45 and will be online for one week at EURONEWS. EURONEWS television is on the cable in most of the European countries.

22 February 2011 - Radiation Intercomparison
An intercomparison case for the radiation codes used in the various climate models that participate in EUCLIPSE WP1 is being set up. The main objective is to quantify the intermodel spread in ToA albedo for typical marine stratocumulus. Also radiation codes that are used in LES models or as stand alone tools are more than welcome to participate. The case is based on observations of stratocumulus off the coast of Africa over the Southern Atlantic Ocean. The runs are not costly, since only a one-time step of the LES code and/or SCM version of a GCM is required and a limited set of output data is asked. We propose a range of cases with different Liquid Water Path (LWP), different options for the microphysics, and different vertical resolutions. For further detailed instructions, motivation and required output we refer to the radiation intercomparison webpage.
16 February 2011 - Final versions CALIPSO-PARASOL products available
As of today the final versions of the CALIPSO-PARASOL observational analysis product are available at the IPSL website. The GCM Oriented Cloud Calipso Product (CALIPSO-GOCCP) is designed to evaluate GCM cloudiness. CALIPSO-GOCCP contains observational cloud diagnostics fully consistent with the ones simulated by the ensemble "GCM+ CALIPSO simulator" (COSP-CAPSIM) : same spatial resolution for the lidar profile before the cloud detection, and same cloud detection threshold. CALIPSO-GOCCP is derived from CALIPSO Level 1 NASA product (the Attenuated Bascatted Signal at 532nm). The second part, namely the PARASOL-1DIREFL is designed to evaluate GCM cloudiness. It is consistent with the directional reflectance simulated by the ensemble "GCM+PARASOL simulator" (COSP-CAPSIM). Read more ........
14 February 2011 - Film made at Cabauw, TU Delft and CNRS Paris
On request of the EU short informative films will be made of some EU projects. The EUCLIPSE project is one of these projects. On February 14th a representative of the EU together with a camera crew visited the site at Cabauw and the TU in Delft in order to shoot some footage. Unfortunately, as you can see in the pictures, the weather did not cooperate.
Last week the EUCLIPSE partner in Paris, Centre National de la Recherche Scientifique Institute Pierre Simon Laplace, was also visited for this purpose.
As soon as the movie is ready it will be available through this website.
26 January 2011 - MODIS simulator available
Since 26th January 2011 the final version of the MODIS-simulator is publicly available here. A tool is presented that allows for a comparison of climate-model simulated cloud and aerosol fields with retrievals by MODIS and other spaceborne passive radiometers.
The tool considers three steps:
(i) the sampling of cloud-top quantities using the model's cloud overlap hypothesis,
(ii) the satellite instrument sensitivity by discarding clouds with little cloud fraction or optical depth, and
(iii) the diurnal sampling by taking into account the satellite overpass time for polar-orbiting satellites. The tool is easy to implement and easy to use, and has been tested widely.

14 April 2010 - Kick-off meeting EUCLIPSE project is postponed
The kick-off meeting of the EUCLIPSE project which was planned on 14-15 April in Haarlem in the Netherlands is postponed. Due to the eruption of the vulcano Eyjafjallajökull, flight traffic was that much hampered it was not possible for most participants to reach the meeting venue. Read more .....
