TWP/MWR/C3 - Instrument failure, Power outage
DataStreams:twpmwrC3.00, twpmwrlosC3.a1, twpmwrlosC3.b1, twpmwrtipC3.a1
Description:
A lightning strike sent the MWR offline. The radiometer suffered extensive damage, was 
removed from the site and sent to the vendor for repair. A spare radiometer was sent to the 
TWP/C3 site and was installed on 12/07. However, some hardaware communication issues 
prevented data collection until 12/10.

TWP/MWR/C3 - REPROCESS- Updated retrieval coefficients
DataStreams:twpmwrlosC3.b1, twpmwrtipC3.a1
Description:
The statistical retrieval coefficients currently in use at the Darwin (TWP/C3) site were 
developed using radiosonde RS80 launched from Manus Island during the TOGA-COARE 
experiment.
Data from Manus Island have minimal seasonality, therefore a single, annual set of 
coefficients was used at all three sites. Retrievals using these coefficients are sufficiently 
accurate especially during the local summer months (December-January). However, the Darwin 
site displays a summer/winter seasonality resulting in larger differences during the 
southern winter (May-
June).
Since we now have enough radiosonde soundings (RS80 and RS90) available at the Darwin 
site, the Darwin coefficients were modified to better reflect the local seasonality.

  • MWR column precipitable water vapor(vap)

TWP/ARSCL/C3 - Reprocess: ARSCL CloudBasePrecipitation field incorrect

Description:
The CloudBasePrecipitation field is incorrect and has no physical meaning.  An ARSCL 
processing error occurred when the smet60s data stream format changed, causing the wrong data 
field to be used to supply precipitation measurements to the ARSCL VAP.  The error caused 
no significant degradation in other ARSCL fields, since manual quality control corrected 
any related errors.

TWP/ARSCL/C3 - Reprocess: MMCR Height offset affects ARSCL cloud boundaries

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.
