Subject:	TWP/C1 - Generator Problem
DataStreams:	twpmfrsrC1.a0, twpmfrsrC1.b1, twpvceil25kC1.a1, twpvceil25kC1.b1, twpsondewnpnC1.a0, twpsondewnpnC1.a1
Description:	On November 18 the generator was turned off due to a fault in the oil pressure sensor. It had been having trouble for at least a day prior to the manual shut-down. ADaM, the MPL, and the WSI were also shut down to prevent an unscheduled power cycle. As a result, there is a block of missing data from November 20-27 for all of the instruments except those connected to the Zeno loggers (SKYRAD, GNDRAD, SMET).

Subject:	TWP/C1 - Incorrect elevation reported in Manus Data
DataStreams:	twpmfrsrC1.a0, twpmfrsrC1.a1, twpmfrsrC1.b1
Description:	(From Bill Clements) We have been using 6m MSL as the station elevation of Momote (Manus). This was based on information posted near the station barometer in the Momote Weather Service Office. It turns out that the official WMO station elevation for Momote is 4m MSL and the upper air elevation is 5m MSL. All Manus instruments except the sonde station are at 4m MSL. The sonde launching station is at 5m MSL.

Subject:	TWP/MFRSR/C1 - 870 nm channel (filter 5) failing on TWP.C1 MFRSR
DataStreams:	twpmfrsrC1.a0, twpmfrsrC1.b1
Description:	The 870 nm channel has been failing and generally is zero or too low. It returns intermittently but the quality/accuracy of the measurement is unknown. It is possible, with caution, some of the intermittent data can be used by an experienced user but generally for this time period the data is erroneous and thus it is colored red.

Subject:	TWP/MFRSR/C1 - Instrument noise problem, Shadowband Misalignment
DataStreams:	twpmfrsrC1.00, twpmfrsrC1.a0, twpmfrsrC1.b1
Description:	There was a slight shading problem from 05/04 to 05/29. Maintenance corrected the problem at around 0200 UTC on 05/29. The shading misalignment resulted in frequently noisy/oscillating data on all broadband/narrowband channels, making data questionable during this time.

Subject:	TWP/MFRSR/C1 - Calibration Drift
DataStreams:	twpmfrsrC1.a0, twpmfrsrC1.b1
Description:	Through this period we see significant drift in all of the MFRSR channels except the 862 nm channel. The most serious drift occurred in the 610 and 665 nm channels which suffered a loss in sensitivity of a factor of 5 or more over the affected period. The MFRSR head was replaced on August 27, 1997 during a RESET visit.

DataStreams:	twpmfrsrC1.a0, twpmfrsrC1.b1
Description:	From 1999/06/15 (or earlier), the MFRSR had shading problem in the morning hours. These shading problems can be identified by the fuzziness in the direct normal irradiance. The problem was corrected on 1999/08/17. Only the direct normal irradiance and the diffuse irradiance are affected, total irradiance is OK.
