-------------------------------------------------------------------------------------------------------------------------------- ECCO Version 4: Second Release [ECCO v4-r2] [ftp://mit.ecco-group.org/ecco_for_las/version_4/release2/interp_climatology/] -------------------------------------------------------------------------------------------------------------------------------- - This directory contains the 'ECCO version 4, release 2' monthly output climatology (interpolated to a 0.5 x 0.5 lat-lon grid) for the variables listed below. - Notes: Each file can be read directly in Matlab or any other netcdf enabled software (http://www.unidata.ucar.edu/software/netcdf/software.html) such as Panoply (http://www.giss.nasa.gov/tools/panoply/). The contents derive from the corresponding 'nctiles_climatology/' contents (ftp://mit.ecco-group.org/ecco_for_las/version_4/release2/nctiles_climatology/, http://dx.doi.org/10.7910/DVN/3HPRZI) through interpolation carried out using the gcmfaces Matlab toolbox (Forget et al. 2015). - List of variables: ADVeHEFF : "Eastward Advective Flux of eff ice thickn" ADVe_SLT : "Eastward Advective Flux of Salinity" ADVeSNOW : "Eastward Advective Flux of eff snow thickn" ADVe_TH : "Eastward Advective Flux of Pot.Temperature" ADVnHEFF : "Northward Advective Flux of eff ice thickn" ADVn_SLT : "Northward Advective Flux of Salinity" ADVnSNOW : "Northward Advective Flux of eff snow thickn" ADVn_TH : "Northward Advective Flux of Pot.Temperature" ADVr_SLT : "Vertical Advective Flux of Salinity" ADVr_TH : "Vertical Advective Flux of Pot.Temperature" DFeEHEFF : "Eastward Diffusive Flux of eff ice thickn" DFeE_SLT : "Eastward Diffusive Flux of Salinity" DFeESNOW : "Eastward Diffusive Flux of eff snow thickn" DFeE_TH : "Eastward Diffusive Flux of Pot.Temperature" DFnEHEFF : "Northward Diffusive Flux of eff ice thickn" DFnE_SLT : "Northward Diffusive Flux of Salinity" DFnESNOW : "Northward Diffusive Flux of eff snow thickn" DFnE_TH : "Northward Diffusive Flux of Pot.Temperature" DFrE_SLT : "Vertical Diffusive Flux of Salinity (Explicit part)" DFrE_TH : "Vertical Diffusive Flux of Pot.Temperature (Explicit part)" DFrI_SLT : "Vertical Diffusive Flux of Salinity (Implicit part)" DFrI_TH : "Vertical Diffusive Flux of Pot.Temperature (Implicit part)" DRHODR : "Stratification: d.Sigma/dr (kg/m3/r_unit)" ETAN : "Free Surface Height Anomaly (Ocean-Ice Interface)" EVELMASS : "Eastward Mass-Weighted Comp of Velocity (m/s)" EVELSTAR : "Eastward Comp of Bolus Velocity (m/s)" MXLDEPTH : "Mixed-Layer Depth (>0)" NVELMASS : "Northward Mass-Weighted Comp of Velocity (m/s)" NVELSTAR : "Northward Comp of Bolus Velocity (m/s)" oceFWflx : "net surface Fresh-Water flux into the ocean (+=down), >0 decreases salinity" oceQnet : "net surface heat flux into the ocean (+=down), >0 increases theta" oceQsw : "net Short-Wave radiation (+=down), >0 increases theta" oceSPflx : "net surface Salt flux rejected into the ocean during freezing, (+=down)," oceSPtnd : "salt tendency due to salt plume flux >0 increases salinity" oceTAUE : "Eastward surface wind stress, >0 increases eVel" oceTAUN : "Northward surface wind stress, >0 increases nVel" PHIBOT : "Bottom Pressure Pot.(p/rho) Anomaly" PHIHYD : "Hydrostatic Pressure Pot.(p/rho) Anomaly" RHOAnoma : "Density Anomaly (=Rho-rhoConst)" SALT : "Salinity" SFLUX : "total salt flux (match salt-content variations), >0 increases salt" SIarea : "SEAICE fractional ice-covered area [0 to 1]" SIatmFW : "Net freshwater flux from atmosphere & land (+=down)" SIatmQnt : "Net atmospheric heat flux, >0 decreases theta" sIceLoad : "sea-ice loading (in Mass of ice+snow / area unit)" SIheff : "SEAICE effective ice thickness" SIhsnow : "SEAICE effective snow thickness" TFLUX : "total heat flux (match heat-content variations), >0 increases theta, W/m2" THETA : "Potential Temperature" WVELMASS : "Vertical Mass-Weighted Comp of Velocity" WVELSTAR : "Vertical Comp of Bolus Velocity (m/s)" - References: Forget, G., J.-M.
