Description:
The Nauru ARCS was installed during the period September-November
1998.  Data were being collected by the end of October, but for the
first several weeks of November, the site was undergoing considerable
change, so data from that period should be used with caution.  The
official site dedication occured on November 20.  Most on-site
activity ended following the dedication so we will consider November
20 to be the beginning of the Nauru operations.  The last members of
the installation team left Nauru on November 24.

TWP/ARSCL/C3 - Reprocess: MMCR Height offset affects ARSCL cloud boundaries
DataStreams:twparscl1clothC3.c1, twparsclbnd1clothC3.c1, twpmmcrmode1bl200511041clothC3.c1,

twpmmcrmode4pr200511041clothC3.c1
Description:
MMCR heights were recorded as being too high by the following amounts:
   Mode 1: 24.8756 m too high
   Mode 2: 25.6249 m too high
   Mode 3: 33.1176 m too high
   Mode 4: 33.1176 m too high

These errors may affect cloud boundaries that are determined by combining MMCR and MPL 
measurements;  radar moments heights will be off by these amounts also.

NOTE: reprocessing is underway.  20060101-20060228 have been reprocessed and archived.  
These data cover the period of TWP-ICE.
