## Real time status : data on GTS monitored by MEDS

## Regional monitoring : example of North Atlantic RDAC

- NARDAC performs a regular monitoring for deployment coordinationThe goal is to achieve a regular density of one float per 3*3 degree**Red** : the float density is correct

- January 2006

- September 2006

- planneddeployements

## Regional monitoring : example of North Atlantic RDAC

- NARDAC performs a regular monitoring for all deployed floats

## Tools for Argo data usage

- Tools for Argo data usage

- Matlab : _[http://www.mathworks.com/](http://www.mathworks.com/)_ Matlab is used for delayed mode processes : salinity correction, deep currents.An excellent commercial software for scientific data handling.
- ODV : _[http://odv.awi-bremerhaven.de/](http://odv.awi-bremerhaven.de/)_ An excellent free software to handle ocean data.Developped by AWI during Woce experiment, continuously upgraded (eg : for SeaDatanet EU project).
- NcBrowse : _[http://www.epic.noaa.gov/java/ncBrowse/](http://www.epic.noaa.gov/java/ncBrowse/)_ An excellent free software to browse NetCDF data.Developped by NOAA.
- Ferret : _[http://ferret.wrc.noaa.gov/Ferret/](http://ferret.wrc.noaa.gov/Ferret/)_An excellent free sofware to handle model and in-situ observations.Developped by NOAA.
- Google: _[http://www.coriolis.eu.org/cdc/](http://www.coriolis.eu.org/cdc/)_ An excellent way to explore Argo and other observations networksProfiles, trajectories
- ETC...
