Research direction

Reproduce the issue with the NOAA wave data and the gribdoctor smoosh and makesurface vectorize commands shown. Trace why nph.tif produces only a coastline outline, and consider the issue resolved when the generated surface displays the ocean data as well.

Written by the indexing model from the issue text.

Description

To reproduce:

  1. Download some wave data from NOAA (http://nomads.ncep.noaa.gov/cgi-bin/filter_wave.pl), select NPH from the dropdown, surface level, select HTSGW variable.
  2. Run gribdoctor smoosh -uw -dev nph.t18z.grib.grib2 nph.tif
  3. Then run makesurface vectorize -b 1 --outfile nph.json nph.tif

Result is the outline of the coast but no visible ocean data.
