Subject: | TWP/MMCR/C2 - Intermittent missing data |
DataStreams: | twpmmcrcalC2.a1, twpmmcrmomentsC2.a1, twpmmcrmonC2.a1, twpmmcrpowC2.a1, twpmmcrmonC2.00, twpmmcrC2.00, twpmmcrmomentsC2.00, twpmmcrcalC2.00, twpmmcrpowC2.00 |
Description: | During the time period identified in this DQR the MMCR was experiencing a variety of hardware problems that resulted in intermittent missing data. |

Description: | The MMCR was not operating properly during this period so the data should not have been used in determining cloud boundaries or radar moments. |

Subject: | TWP/VCEIL/C2 - Reprocess: Incorrect serial_number and sum_backscatter fields |
DataStreams: | twpvceil25kC2.b1 |
Description: | Attribute serial_number: In most cases, this field is not representative of the actual serial number of the instrument because the value did not change when an instrument changed locations or was replaced with a spare. Variable sum_backscatter: An out-of-range condition for the "sum of detected and normalized backscatter" was reported as 0 instead of missing (-9999). The valid range is 0 - 0.0999 /srad. This DQR also applies to a1 level data. |

Subject: | TWP/MPLCMASK/C2 - Cloud layer metadata misleading |
DataStreams: | twp30smplcmask1zwangC2.c1 |
Description: | The comment in the header for cloud_base_layer indicates that a value of -1 indicates that no cloud is detected. For the specified time range, a value of 0 indicates that no cloud is detected. Values greater than zero indicate cloudy conditions, otherwise it is clear. |
