NPEO PMEL/CRREL Ice Temperature and Mass Balance Buoys for 2003, 2004, and 2005
Because of the large temperature arrays presented by the CRREL buoys, their data
is provided in three or four separate files. All contain header information
ended by a line with a single character '#', followed by the data in
tab-delimited ASCII columns. The first five columns provide a time stamp for
that data line.
- IceTemp files: Internal Ice Temperature (degrees C) from the air through the
ice into the ocean beneath typically every 10 cm and every 2 hours. The header
lists the heights/depths at which temperature was measured. A depth of 0 is the
position of the top of the ice at the time of deployment, positive numbers are
heights above the surface of the ice, negative numbers are depths from the top
surface of the ice. To the right of the time stamp the remaining columns list
measured temperature at those depths. Missing data are flagged as -99.0.
- Mass files: Ice and snow thickness measured measured with acoustic pingers,
a positive snow depth and a negative ice bottom depth, both measured in cm,
typically every 2 hours. Missing data is flagged as -9999.0. Buoys 2003B
and 2005A either were not equipped with top and bottom pingers or they failed,
so a mass balance file is not included. Mass balance information may be
inferred from the temperature profile from the thermistor string, and such an
interpretation will be available on the CRREL Buoy Website when available.
- Position files: Position usually from GPS, but a few from Argos, usually
recorded hourly.
- Met files: Atmospheric pressure and air temperature typically recorded every
2 hours. A few buoys are missing pressure. Missing data is flagged as -9999.0.
These buoys are complimented by PMEL Weather and Radiometer buoys as well
as the JCAD Buoys deployed by JAMSTEC.
