		:comment = "The W-band radar is a vertically-pointing cloud radar designed for ship deployments. See reference for specifications. The radar was deployed with a 10 dB attenuator during this cruise to prevent malfunctioning transmit/receive switches. Thus, radar echoes from non-precipitating clouds tend to be absent while clouds with larger drops capable of rain are usually detected. The radar only operated successfully on the second half of the ATOMIC ship based experiment. The radar was turned off a few times when the NOAA P3 aircraft was flying within close range. The radar was also turned off during a several day port stop from Feb 4 through Feb 6. The pitch-roll motion stabilization system failed twice and was reset with a software protocol. It is unclear how long the data were not motion-compensated. These times can be identified by coarser vertical and horizontal resolution since the radar was not pointing true vertical, acting as a low-pass filter. The radar is property of Dr. Paquita Zuidema at University of Miami and deployed through her NOAA CPO CVP grant. The radar was operated by NOAA PSL during this cruise." ;
