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.
Measurements:twpmwrlosC3.b1:
  • MWR column precipitable water vapor(vap)
  • Averaged total liquid water along LOS path(liq)
twpmwrtipC3.a1:
  • Total water vapor along zenith path using tip-derived brightness temperatures(vaptip)
  • Total liquid water along zenith path using tip-derived brightness temperatures(liqtip)
