Subject: | NSA/HSRL/C1 - Reprocess: Missing atten_beta_r_backscatter |
DataStreams: | nsahsrlC1.a1 |
Description: | Due to a processing error the atten_beta_r_backscatter variable is missing 100% of the time. This is not a critical problem as the rest of the subsequent derived fields are properly reported. Data will be reprocessed at a later date. |

Subject: | NSA/HSRL/C1 - Laser instability |
DataStreams: | nsahsrlC1.a1 |
Description: | The HSRL laser still exhibits instability causing calibration uncertainty, especially for the beta_a (extinction profile), beta_a_backscatter (backscatter profile), and depol (depolarization ratio). Cloud and aerosol layer heights are quantitative and accurate however the calibrated quantities above have increased uncertainty. Nevertheless, the sensitivity of the HSRL in this degraded mode is still superior to other lidar on site (MPL and VCeil). The laser failed on 07/19/2013 at 22:30. |
