NSA/AERI/C1 - External Temperature Sensor Failed
DataStreams:nsaaerich1C1.a1, nsaaerich2C1.a1, nsaaerisummaryC1.a1, nsaaeriengineerC1.a1
Description:
There appear to have been some problem with the external temperature sensor. The outside 
temperature sensor data is not used in the derivation of the spectral IR data and are just 
a diagnostic tool. We have not found what
caused this behaviour.
Measurements:nsaaerisummaryC1.a1:
  • Ambient air temperature at hatch opening(outsideAirTemp)

nsaaerich1C1.a1:
  • Ambient air temperature at hatch opening(outsideAirTemp)

NSA/AERI/C1 - AERI extended range detector at Barrow
DataStreams:nsaaerich1C1.a1, nsaaerich2C1.a1, nsaaerisummaryC1.a1, nsaaeriengineerC1.a1
Description:
The extended range detector had failed and a borrowed replacement detector was installed. 
The replacement detector had enough air present in the dewar to cause the cryogenic 
cooler to work at full current. The detector was still warmer than optimal and there is more 
noise present in the data than is considered normal. The data must be used with 
discretion. The system was shut off on 020516 due to noise and rising detector temperatures.
