TPXO8-atlas, version 1,
history mask: patches of local HR solutions are shown
with different colors. Arrows point patches DIFFERENT from version 0 for 8 major constituents.
Version 1 does not differ from version 0 elsewhere.
Versions 0 and 1 are the same for M4,MM,Mf,MN4,MS4.
TPXO8-atlas, version 1, now replaces zero version, which was 1st one from new generation atlas
solution. Like older ATLAS solutions a new generation solution combines a basic
global solution (TPXO8, obtained at 1/6 resolution) and
high resolution (HR) local solutions. Unlike all
previous ATLAS solutions, it keeps resolution of HR
solutions rather then averaging them on coarser
grid. This provides dramatic improvement in tidal
predictions for coastal areas. For user convenience we
provide TPXO8-atlas in several formats:
1. our traditional binary format (OTPS
2. netcdf format;
3. atlas-compact format;
Due to HR the files are large, thus we provide one tidal
constituent/file for first 2 formats. Atlas-compact
format contains all constituents, but at various
resolution (i.e. 1/30 resolution where the patches are,
and 1/6 resolution for the rest of the Ocean).
Atlas-compact is readable by next version of OTPS
(OTPS2) to provide extraction of harmonic constants/tide
prediction at any location. OTPS2 is functionally the
same as OTPS and works for any our model plus it also is
applicable for the Atlas-compact.
now provides functionality for extracting a local
tidal solution (bathymetry, elevations and transports)
from TPXO8-atlas-compact for any given rectangular
area and outputting the solution in the regular OTIS
binary format at 1/30 degree resolution. Thus a user
has the option to deal with an area of interest only
in a simpler uniform
IMPORTANT! You have to download the newest
version of TPXO8-atlas-compact for this new feature to
work properly. TPXO8-atlas-compact versions download
before April 2, 2014 will not work with this new
misfit (sm) to pelagic and some local tide gauges
