USCGC Healy HLY-02-01 Hourly Position and Weather Data [NCAR/EOL]

This dataset is a composite of several ship underway datasets produced by
the U.S. Coast Guard aboard the USCGC Healy during the Spring SBI Process
Cruise of 2002 (hly-02-01). Routine data logging procedures for underway data
aboard the Healy archive data of different types in physically separate files.
This has the unfortunate effect of separating interesting data from the
location of the ship when the measurement was taken. To remedy this situation, a perl script was written by the author to produce
a composite file that contained both ship position and weather information
collected during the above mentioned cruise. This file is a composite of the
PCode-Aft_GGA position datafiles (1 second resolution) and the RMYoung-AIR
weather datafiles (3 second resolution). The composite is a collection of grab samples (not averages) at approximately
1 hour intervals during the cruise. The composites were constructed by starting
with the time at which the weather observation occurred. The position files were
then searched until the position at the observation time was found. If the times
matched or were within 10 seconds of one another, the weather and position data
were written to the composite file. The position information was converted from
Degrees Minutes Seconds format (DDDMM.SSS) to a Decimal Degrees format
(DDD.DDDDD)
