See :ref:`data_access`.

Data Files
~~~~~~~~~~

TropFlux fluxes and flux related meteorological variables are available in 
daily and monthly time scales and are available from the following directories :

 - <http://www.locean-ipsl.upmc.fr/~tropflux/data/monthly/>
 - <http://www.locean-ipsl.upmc.fr/~tropflux/data/daily/>

Size of daily files : almost 1GB

Size of monthly files : 32 MB

* :file:`q2m*.nc` file contain TropFlux specific humidity at 2m above the sea surface.

  Units are in :math:`g/kg`.

* :file:`t2m*.nc` files contain TropFlux air temperature at 2m above the sea surface.

  Units are in :math:`°C`.

* :file:`sst*.nc` files contain TropFlux sea surface temperature.

  Units are in :math:`°C`.

* :file:`ws*.nc` files contain TropFlux wind speed at 10m above the sea surface.
  The `gustiness` correction applied to wind speed for turbulent heat flux
  computations (see `Praveen Kumar et al. (2011) <http://www.locean-ipsl.upmc.fr/~tropflux/papers/TropFlux_paper_accepted_r.pdf>`_ for details) is not applied in this file.

  Units are in :math:`m/s`.

* :file:`swr*.nc` files contain TropFlux net shortwave radiation at the sea surface.
  
* :file:`lwr*.nc` files contain TropFlux net longwave radiation at the sea surface.

* :file:`lhf*.nc` files contain TropFlux latent heat flux.

* :file:`shf*.nc` files contain TropFlux sensible heat flux.

* :file:`netflux*.nc` files contain TropFlux net surface heat flux.

  Units are in :math:`W/m^2`.

* :file:`tau*.nc` files contain TropFlux wind stress magnitude.

* :file:`taux*.nc` files contain TropFlux zonal wind stress.

* :file:`tauy*.nc` files contain TropFlux meridional wind stress.

  Units are in :math:`N/m^2`.
