Subject: | SGP/SIRS/E6 - Bad upwelling long_wave hemisp |
DataStreams: | sgpsirsE6.b1, sgpsirs20sE6.a0 |
Description: | The upwelling longwave hemispheric (up_long_hemisp) values were intermittently missing or incorrect. Sensor was replaced on 7/19 and the problem was resolved. |

Subject: | SGP/SIRS/E20 - Downwelling LW incorrect |
DataStreams: | sgpsirsE20.b1, sgpsirs20sE20.a0 |
Description: | The downwelling longwave hemispheric shaded (down_long_hemisp_shaded ) values periodically were missing or incorrect. Connections on the Multiplexer were reseated on 7/13/2011 at 18:11 resolving the problem. |

Subject: | SGP/SIRS/E13 - Intermittent upwelling longwave |
DataStreams: | sgpsirsE13.b1, sgpsirs20sE13.a0 |
Description: | Beginning 9/19/2011 @ 15:12, the upwelling longwave values are often spiking to large and small values throughout the day. A multiplexer was found to be the problem and the ops replaced it on 10/27/2011. Incorrect data are not recoverable for the specified time range. However, good data exists within the time range. The SGPQCRAD VAP data stream provides flags for "good" data and appears to accurately flag bad data during this time range. Users are advised to use this data stream to screen for correct up_long_hemisp values. |

Subject: | SGP/SIRS/C1 - NIP Failure |
DataStreams: | sgpsirsC1.b1, sgpsirs20sC1.a0 |
Description: | The short_direct_normal (NIP instrument) cable failed (broken wire in NIP connector) during this time period. Data are not recoverable. An estimate of direct normal values can be derived using the following formula: short_direct_normal = (down_short_hemisp - down_short_diffuse_hemisp)/cos(zenith angle) |
