Looking beyond our prototype 

We are thinking about ways that our prototype can in some way be connected with similar tools such as portal.c3s-magic.eu., which is being developed by in the MAGIC project. Note, this tool will evolve further and the site is likely to change in the future.

Recent updates and new look !

We have updated the prototype and slightly modified the layout and colors. The updates included also fixing some minor bugs in the plots and documentation. A list of what has been done can be found hereafter.

  1. Legend names have been shortened and replaced by the identification number of the simulation in the meta data table. You can still get the full legend name when hovering on the chart.
  2. More info boxes have been added and an explanation of the various functionalities within each item have also been added. You have to collapse the box of each item title to get an overview.
  3. An item related to the COPERNICUS terms of use have been added in the main dashboard header.
  4. Chart and maps documentation have been improved and few inconsistencies fixed as well.

We are still counting on your feedback to improve more the prototype so that we satisfy your needs and requirements.

Fianlly, RCP8.5 results will be added soon.

We have exceeded 1500 users !


We are happy to publish a new achieved record related to the number of users. Congratulations!

We have exceeded 1500 users since the prototype has been launched

That is quite satisfying as it shows that our Prototype has been successfully implemented and filled a real gap between providers and users of climate change information.

Have a nice week.

Results for RCP8.5/GCMs will be added soon


We have started processing global climate models (GCMs) assuming the RCP8.5 emission scenario as it was requested by many users. We will add those results to the app as soon as they are ready.

Many thanks again for your collaboration and looking forward for more feedback on our website and app.

Congratulations ! More than a thousand users since the prototype has been launched in the beginning of 2018

We have registered 1174 users since January 2018. We are still collecting your valuable feedbacks and making new training sessions. If you want to participate, just contact us !



Another interesting table showing the top ten countries that used the prototype for the last month. Brazil is on the top with 50 sessions followed by Canada and Finland. Even though most of Norwegians were on vacations, we noticed few activities as well

Feedbacks on the prototype

We have now received some feedback and suggestions on this prototype. Here are some of them in italics together with our thoughts written in bold.

  • Missing important features, most notably *being able to choose RCP scenario in the settings stage* right now if one plots individual models the figure gets WAY too crowded, because there are too many models and scenarios. The only way to look at a specific scenario is by grouping and deselecting the undesired scenarios, which is a bit cumbersome and more difficult. We could have added RCPs, but have not got this far yet. Also purpose of this prototype is to convey information about models and their quality (based on one example), and not to provide scenarios for the future. The purpose is to give a “crowded” first impression, but there are ways to “uncrowd” the figure, for instance by clicking on the legends or the metadata table to select or deselect/hide individual or groups of models.  
  • Too many models from the same institution –> introduces bias in the ensemble mean (NASA GISS gets 5 “votes” per scenario –> undemocratic ensembleThese are different realisations and their differences reveal information about natural variability. Again, it is possible to hide some of the runs. One should not compare averages of ensemble members for one given model if the ensemble has different size to that of other ensembles or if compared with single model runs.  
  • It would be useful to quickly see the most important metadata when hovering over a simulation in the legend, e.g. the resolution. It’s in there and has already been implemented for the data users who have more options. You need to group the models by e.g. “Horizontal.resolution” and the information will then show up in the hoover.
  • Is it possible to remove the window-within-a-window style of the page? Can the whole “page” be just the actual application frame? Yes, we are working on this, and the recent changes will soon be updated  on our server. 
  • Will there be any other parameters besides temperature and precipitation? We could have added more variables, but since this is a prototype, we have limited the variables to the most commonly used ones for users of climate information. We may include wind in the future. 
  • When you open the item 1 (i.e., the area selection), the zoom in/out buttons are overlapping with the text. Thanks! We will look into this.
