Subject: | SGP/VCEIL/C1/B4/B5/B6 - Reprocess: Incorrect serial_number and sum_backscatter fields |
DataStreams: | sgpvceil25kB4.b1, sgpvceil25kB5.b1, sgpvceil25kB6.b1, sgpvceil25kC1.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 collected prior to b1 level. |

Subject: | SGP/VCEIL/C1 - Range normalization |
DataStreams: | sgpvceil25kC1.b1 |
Description: | The range gate data were not normalized during this period because, when the CL31 was first deployed, I was uncertain about this parameter and returned it to its default setting of "off". Range gate normalization was enabled after receiving the following from Vaisala: ''We do recommend to keep this 'profile noise_h2' setting on. If 'profile noise_h2' is off, then range correction of the signal would freeze at 2400 m, unless the algorithm has detected a cloud region. This had been designed to make profiles in CL-VIEW look less noisy and to emphasize the presence of clouds.'' |
