The MeSOLaB system compute more or less 250 trajectories every day, accessible through the interactive map

MeSOMaP is an interactive map showing positions of autonomous profiling floats and producing drifting simulations in real-time. The numerical trajectories are computed for the whole Argo float array and the OAO floats through a service initiated by the MeSOLaB project. Trajectories are computed using daily sea velocities provided routinely by the MERCATOR team at a global scale and a 1/12° resolution. The MeSOLaB system allows also to sample 2 dimensional fields along a float trajectory, and thus hindcast/forecast data measurements along a float path.

The MeSOLaB system compute more or less 250 trajectories every day, accessible through the interactive map as soon as the Coriolis database is updated. This represents a huge amount of data for which an adapted interactive vizualisation tool is required. With the MeSOMaP you can choose your parameters (time period, database, drifting depth) and find immediatlely the informations you’re looking for. The MeSOMaP only show a selected number of floats depending on your map settings and time period. You can then have a view of the full Argo array at global scale, while details appear instantly when zooming on a specific place. Clicking a float position will set the map boundaries to the current float trajectory. You can show 7-days forecasts or reanalysis in the database panel. The forecasts display is resource-consuming for your computer, so you should enable it only on small space scales to keep a responsive map. 

Design your own numerical experiment and share it 

In addition to these data exploration capabilities, the MeSOMaP allow you to submit your own float positions and get the forecast/hindcast back in near real-time. These positions are then accessible by enabling the «Public» checkbox in the database form while data are send to you by email. Doing so, you can design your own numerical experiment by requesting numerical trajectories. If you want to share the map in front of you with others, click on the «Share» link and copy the link to the clipboard. By clicking this link, you’ll be displayed the same map as you see.  It is also possible to set this link as favorites for a quick view of specific places you could be interested in.

How to submit a float position ? 

First of all right click on the map ! A red marker appears where you clicked. Drag the marker anywhere you want, in the ocean is generally a good idea. You can zoom on the marker by left-clicking it.
Access the submission form by clicking the float icon. You can then choose the parameters for the simulation : The tag is a user defined parameter. It has to be 6 characters long and it is personal to you. When you submit a tag for the first time, the system check its availability. If the tag is already choosen, you’ll receive an error and you will have to choose an another tag for your experience. In the case where the tag is available, well done, it is yours now and the simulation will be proceed ! You can now use this tag for future submissions.
The profile number is a new position for a same tag. You have to submit only one time the couple  tag/profile_number, otherwise you’ll get an error. So don’t forget to raise your profile number for every new submissions.
Take care to dates : no past forecasts are allowed, reanalysis starts on 2014-11-05 and ends 7 days before last Wednesday. When all parameters seem ok to you, click on the «Submit» button. If the submission is successful, a confirmation box is diplayed and the marker color turn to green. Otherwise an error is displayed for the concerned parameters. After the MeSOLaB trajectory computation, the float will appear in the « Public » database section

Share  your map

Clicking the share button made a box appear with a link to the current map. You can copy this link to the clipboard and send it. The person receiving this link will then be brought directly to the map you have in front of you, with the tunning you made.
