Global Attributes:	type: ROMS GRID file title: East Coast Community Ocean Forecast System (ECCOFS) 3-km forecast grid. creator: John Wilkin - Aug 24, 2023, @Hanse-IAS.de details: Created using files in /Users/wilkin/Dropbox/_roms-db/eccofs/izo. Basic grid is made with izogrid (from Sasha Shchepetkin) with input ECCOFS_v5.dat. The grid is rectangular in a Mercator projection, and rotated approximately 37 degrees counter-clockwise from east. izogrid output is remapped by linear interpolation using eccofs_stretching.m. Dimensions were selected so that factor of 2 decimation to the 6-km mixed resolution 4D-Var inner loops grid has efficient NtileI,NtileJ partitions. land_sea_mask: Initially interpolated from WATL, then edited in editmask with guidance from GSHHS (high) coastline. 3-km and decimated 6-km grids interactively compared for kinematic consistency of islands, bays and apaages. Script eccofs_grid_mixedres_issues.m used to find problematic cells in u,v grid. 3-km and decimated 6-km grids interactively compared for kinematic consistency of islands, bays and passages. Script eccofs_grid_mixedres_issues.m (J. Wilkin 28-Jan-2024) used to find problematic cells in u,v grid citation: GEBCO (2023). GEBCO Compilation Group (2023), doi:10.5285/f98b053b-0cbc-6c23-e053-6c86abc0af7b hrawinfo1: First record of hraw interpolated on eccofs grid from median 10x10 filter of Gebco 23 bathymetry hrawinfo2: cut off hmin=5m and hmax=5000m from record 1 of hraw, in the areas with large r-factor, use hmin=20 hrawinfo3: Local smoother with r-factor limit 0.35. In areas with high r-factor, blend it with bathy from local smoother with r-factor limit of 0.3 hrawinfo4: Blended with Mercator bathymetry hrawinfo5: additional smoothing in areas where decimation to coarse grid produced stiff coarse bathymetry hrawinfo6: log shapiro on h>2000, then 4-th order shapiro NCO: netCDF Operators version 5.1.5 (Homepage = http://nco.sf.net, Code = http://github.com/nco/nco) history: Mon May 6 20:15:35 2024: ncatted -a subdomain,global,c,c,Extracted from /Users/wilkin/Dropbox/_roms-db/eccofs/grid/grid_eccofs_3km_08.nc for subdomain xi=490,1168, eta=758,1280 using script extract_roms_subset_eccofs_4_dorian.sh (John Wilkin) grid_sabeccofs_3km_08.nc Mon May 6 20:15:33 2024: ncks -4 -L 1 --overwrite -d xi_rho,490,1168 -d eta_rho,758,1280 -d xi_u,490,1167 -d eta_u,758,1280 -d xi_v,490,1168 -d eta_v,758,1279 -d xi_psi,490,1167 -d eta_psi,758,1279 /Users/wilkin/Dropbox/_roms-db/eccofs/grid/grid_eccofs_3km_08.nc grid_sabeccofs_3km_08.nc subdomain: Extracted from /Users/wilkin/Dropbox/_roms-db/eccofs/grid/grid_eccofs_3km_08.nc for subdomain xi=490,1168, eta=758,1280 using script extract_roms_subset_eccofs_4_dorian.sh (John Wilkin) Unlimited_Dimension: bath
