== Configuration description

The C1D_PAPA configuration is a 1D model (one water column called NEMO1D, activated with CPP key key_c1d), located at the  [http://www.pmel.noaa.gov/OCS/Papa/index-Papa.shtml PAPA station 145W-50N].

NEMO1D is useful to test vertical physics in NEMO (turbulent closure scheme, solar penetration, interaction ocean/atmosphere.,...)[[BR]]
Size of the horizontal domain is 3x3 grid points.

This reference configuration uses a 75 vertical levels grid (1m at the surface), the GLS (key_zdfgls) turbulence scheme with K-epsilon closure and the CORE BULK formulae. The atmospheric forcing comes from ECMWF operational analysis with a modification of the long and short waves flux. This set has been rescaled at a frequency of 1h. 1 year is simulated in outputs, see below (June,15 2010 to June,14 2011)

This configuration is available for NEMO v3.6 and later.

[http://www.geosci-model-dev.net/8/69/2015 Reffray et al.]  describes some tests on vertical physic using this configuration.
