Global surface current Data Product
A new product is available here:
http://www.legos.obs-mip.fr/sudre/gekco_form
Each netcdf file's name is labelled: v_gekco_exp_b_YYYYMMDD.nc with YYYYMMDD: date of the data (YYYY: year, MM: month, DD: day)
Each daily file includes 11 fields corresponding to the GEKCO product :
- Longitude in degrees: lon (vector field)
- Latitude in degrees: lat (vector field)
- Absolute Dynamic Topography (from AVISO DT_MADT_UPD) in (cm): h (matrix field)
- Zonal wind stress component (from NCDC Blended product) in (Pa): tx (matrix field)
- Meridional wind stress component (from NCDC Blended product) in (Pa): ty (matrix field)
- Zonal geostrophic current component in (cm/s): ug (matrix field)
- Meridional geostrophic current component in (cm/s): vg (matrix field)
- Zonal Ekman current component in (cm/s): ue (matrix field)
- Meridional Ekman current component (cm/s): ve (matrix field)
- Zonal total surface current : sum of zonal geostrophic and Ekman current component in (cm/s): u (matrix field)
- Meridional total surface current : sum of meridional geostrophic and Ekman current component in (cm/s): v (matrix field)
Note : the flag value for each field is 999 (missing values in the netcdf file)
