Subject: | SGP/AERI/B4 - Intermittent Failure of LW detector |
DataStreams: | sgpaerisummaryB4.a1, sgpaerich1B4.a1, sgpaeriB4.00, sgpaeriengineerB4.a1 |
Description: | The amplifier gain for the long wave (LW) detector intermittently failed. The result was a decrease in LW responsivity by a factor of 2 whenever this occurred. The loss of responsivity will increase the noise of the LW data. The user will need to determine whether this increase in noise is significant enough to affect the data quality for their application. The amplifier rapidly changed from failed to working. When the amplifier was working the data are all green (good). |
Suggestions: | If the LW responsivity is greater than 0.8, the data can be considered green (good). To be safe the user can just select these data. For values of LW responsivity that are below this value, the user will have to determine if the extra noise affects data quality for their application |
