Station Data Tools

hb_extract - Extracts stations from Hydrobase station files by a variety of criteria.
hb_propcalc - Computes properties at each pressure level in a station and outputs a Hydrobase format station file containing all the properties specified with the -P option.
hb_xyprop - Creates a listing of x,y property pairs. Use hb_propcalc to compute properties and pipe the output to this utility.
hb_xyzprop - Creates a listing of x,y,z property triplets.
hb_mssort - Sorts file(s) of HydroBase stations by geographic squares. The size of square is specified by the -S parameter. Up to MAXF files can be simultaneously opened. Any stations that do not fit into an open file are stored in a file called msextra.dat -- which can be sorted subsequently. An accounting of numbers of stations in each file is written to stdout.
hb_stationsort - Creates a list of input files.
hb_siftsta - Determines whether a station has a value of a property which falls between specified minimum and maimum values. If so, it prints the station to stdout. Profiles can be separated by saving the ones that don't meet the criteria to -Rreject file.
hb_siftlevs - Determines whether an observation level has a value of a property which falls between the specified min/max ranges. If so, it prints the scans to stdout in Hydrobase Station format. Scans that do not meet the criteria are written to the file specified by -R.
hb_columns - Computes properties specified with -P option at each depth level in a station and outputs a column listing of each level plus any optional lat/lon/year/month/station/cruise of the observation.
hb_getpos - Extracts latitude/longitude from Hydrobase data files and writes it to the stdout device or an output file specified with -O.
