Two CRREL snow/ice balance buoys and JAMSTEC's JCAD-4 were also deployed at NPEO in 2002. Data from those buoys will be archived separately. One weather station buoy and two radiometer buoys were deployed in 2002. Weather station redundancy is available from the JCAD-4 buoy. AirT1 was fan-aspirated. AirT2 was in a thermistor shield. The wind-sensor was a black RMYoung Arctic model; however if winds are reported as 0 for more than a few records, as in December 2002 and January 2003, we assume the rotor was frozen. Wu is Eastward wind component. Wv is Northward wind component. Wdir is wind direction From. One set of radiometers consisted of an Eppley PSP and PIR, and the other set was a Kipp & Zonen CM22 pyranometer and CG4 pyrgeometer, both deployed adjacent to the weather station buoy on the same floe. At least one set of radiometers functioned through summer 2002. The data from the radiometers are not useful after mid-to-late September. The radiometers had heaters and a fan constantly blew air over the surface of the radiometers. However, the heaters and fans were powered by solar panels and therefore stopped in late September. Neither radiometer buoy recorded position information. The drift track from the weather station buoy applies to each. Radiation units are in Watts/m^2. Missing data is flagged with the value '1.e35' in the weather station file and '1.e35' in the radiometer files.

This was powered by the radiometer solar panels and sent back an image via Iridium every 6 hours.
