Intercomparisons of Cloud Observations from the AL S-band Profiler and the ETL K-band Millimeter-Wave Cloud Radar on the R/V Ronald H. Brown during Nauru99

Nauru99 took place in the western and central Pacific during June and July 1999. During Nauru99, a diverse suite of instruments was located on the research vessel (R/V) Ronald H. Brown to measure cloud radiative interactions, among other things. An important observational tool for the Atmospheric Radiation Measurement (ARM) Program is the Millimeter Wave Cloud Radar (MMCR) developed for ARM by the Environmental Technology Laboratory (ETL) (Moran et al. 1998). The MMCR is a sophisticated instrument designed to continuously monitor the vertical structure of a variety of clouds. It is designed to operate unattended and provide cloud observations with high vertical and temporal resolution.
