DataStreams: | sgpaeriB4.00, sgpaerich1B4.a1, sgpaerich2B4.a1, sgpaeriprofB4.c1, sgpgaeriprofB4.c1, sgpaerisummaryB4.a1, sgpaeriengineerB4.a1 |
Description: | The detector dewar failed during a power failure at midnight GMT on 10Feb02. All data through 10Feb02 are good. The detector dewar failure resulted in the detector not being cooled. A warm detector produces only noise. There is no usable data beginning 11Feb02 through 14Feb02 at which time the system was shut off and the detector removed for repair. All spectral data is not usable in this period. Some meta data such as temperatures are usable. |

Subject: | SGP/AERI/B4 - Intermittent Failure of LW detector |
DataStreams: | sgpaeriB4.00, sgpaerich1B4.a1, sgpaerisummaryB4.a1, 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). |

Subject: | SGP/MFRSR/E10 - Data not quality assured |
DataStreams: | sgpmfrsrE10.a0, sgpmfrsrE10.b1 |
Description: | Data from October 1, 1999 through March 2001 from MFRSR.E10 should be used with caution. During this time period only minimal quality control and maintenance were provided to the SGP extended facility MFRSRs because these data were considered to be of questionable value under the best of circumstances. That decision was reversed in 2001 when Joe Michalsky identified a means to make the MFRSR data scientifically useable. In the interim, the MFRSRs developed problems with shading, leveling, calibration and all-out hardware failures and the stock of spare MFRSRs was depleted and not replenished. Most of the shading and leveling problems have now been corrected in the field as well as possible, but almost all of the extended facilty MFRSRs still need to be recalibrated or replaced. |

Description: | The time response of the temperature measurement was 1.0 sec instead of 0.1 sec (which it should have been to accommodate the 5Hz sample rate). |
