usage with complete fes2014 ocean_tide files

[ezaron]

Hello: I am trying to use the example/fes_slev.c program to generate tide predictions with the FES2014 data files I downloaded in 2019.

I have adapted the fes_slev.c program to point to the .ini files that came with the FES2014 donwload. When I run the program, the tide predictions are very different from the tide predictions generated from example data in this git repository under test/data. I wonder if you can provide an example output of fes_slev.c which uses the full FES2014 model?

Here is the output of fes_slev.c when I use the full FES2014 ocean_tide and load_tide fields: build/examples$ ./fes_slev_edz JulDay Hour Latitude Longitude Short_tid LP_tid Pure_Tide Geo_Tide Rad_Tide 12053.00000 0 59.195 -7.688 -92.831 1.014 -91.817 -89.047 2.769 12053.04167 1 59.195 -7.688 -131.850 0.987 -130.863 -127.487 3.376 12053.08333 2 59.195 -7.688 -137.119 0.959 -136.160 -133.091 3.069 12053.12500 3 59.195 -7.688 -107.177 0.931 -106.246 -104.324 1.922 12053.16667 4 59.195 -7.688 -48.534 0.902 -47.632 -47.419 0.213 12053.20833 5 59.195 -7.688 25.530 0.873 26.403 24.763 -1.640 12053.25000 6 59.195 -7.688 96.132 0.843 96.975 93.827 -3.148 12053.29167 7 59.195 -7.688 144.123 0.812 144.935 141.044 -3.891 12053.33333 8 59.195 -7.688 157.545 0.782 158.326 154.652 -3.674 12053.37500 9 59.195 -7.688 134.338 0.750 135.089 132.514 -2.575 12053.41667 10 59.195 -7.688 80.504 0.718 81.222 80.356 -0.866 12053.45833 11 59.195 -7.688 8.294 0.686 8.980 10.042 1.062 12053.50000 12 59.195 -7.688 -65.386 0.653 -64.733 -61.967 2.766 12053.54167 13 59.195 -7.688 -122.488 0.620 -121.868 -118.035 3.833 12053.58333 14 59.195 -7.688 -149.138 0.586 -148.551 -144.551 4.000 12053.62500 15 59.195 -7.688 -139.819 0.552 -139.267 -136.029 3.237 12053.66667 16 59.195 -7.688 -97.658 0.518 -97.140 -95.398 1.742 12053.70833 17 59.195 -7.688 -32.831 0.483 -32.348 -32.466 -0.118 12053.75000 18 59.195 -7.688 38.184 0.448 38.632 36.756 -1.876 12053.79167 19 59.195 -7.688 95.824 0.413 96.237 93.175 -3.062 12053.83333 20 59.195 -7.688 124.784 0.378 125.162 121.785 -3.378 12053.87500 21 59.195 -7.688 119.168 0.342 119.511 116.723 -2.788 12053.91667 22 59.195 -7.688 81.910 0.306 82.216 80.727 -1.489 12053.95833 23 59.195 -7.688 22.556 0.270 22.826 23.006 0.179

The netcdf header of the ocean_tide/m2.nc file reports this (from files downloaded in 2019):

// global attributes: string :cdm_data_type = "Grid" ; string :license = "http://www.aviso.oceanobs.com/fileadmin/documents/data/License_Aviso.pdf" ; string :title = "FES2014b tide elevations" ; string :product_version = "b" ; string :summary = "global tide solution using finite element mesh, T-UGO barotropic model and data assimilation of altimetry and tidal gauges" ; string :project = "FES2014" ; string :credits = "LEGOS, NOVELTIS, CLS, CNES" ; string :contact = "aviso@oceanobs.com" ; string :references = "http://www.aviso.altimetry.fr/en/data/products/auxiliary-products/global-tide-fes/description-fes2014.html" ; string :date_created = "2016-10-20 12:34:35" ; string :history = "2016-10-20 12:34:35:creation" ; string :Conventions = "CF-1.6" ; string :geospatial_lat_units = "degrees_north" ; string :geospatial_lon_units = "degrees_east" ; :geospatial_lat_resolution = 0.0625 ; :geospatial_lon_resolution = 0.0625 ;

Can you provide check values so I can verify if I am using the software correctly with the full FES2014 fields?

I added an example of output with the FES2014 v1.2 grids. The example file had not been updated since 2016. I did it.
