Two CRREL snow/ice balance buoys and JAMSTEC's JCAD-8 were also deployed during NPEO 2004, but at different locations. Data from those buoys will be archived separately. One weather station buoy and one radiometer buoy were deployed in 2004. Positions are ARGOS recorded for the weather buoy only. AirT1 was in a thermistor shield. AirT2 was ventilated. The wind-sensor was a black RM Young Arctic model; however, if winds are reported as 0 for more than a few records we assume the rotor was frozen. Wu is Eastward wind component. Wv is Northward wind component. Wdir is wind direction From in degrees True, obtaining magnetic declination from NOAA's Geomagnetism website at (http://www.ngdc.noaa.gov/seg/geomag/geomag.shtml). The set of radiometers consisted of a Kipp & Zonen CM22 pyranometer and CG4 pyrgeometer, both deployed adjacent to the weather station buoy on the same floe. The radiometers had heaters and a fan constantly blew air over the surface of the radiometers. The heaters and fans were powered by solar panels and therefore stopped in late September. However, the extreme melt season in 2004 badly affected both buoys, melting the snow and ice under the ablation shield until both tilted in late July. Wind and radiation measurements became unreliable about that time. The drift track from the weather station buoy applies to each. Radiation units are in Watts/m^2. The missing data flag in both files = '1.e35'.

These were powered by solar panels and sent back an image via Iridium every 6 hours.
