| Subject: | TWP/QCRAD/C3 - Tracker inoperative |
| DataStreams: | twpqcrad1longC3.s1, twpqcrad1longC3.c1, twpqcrad1longC3.s2, twpqcrad1longC3.c2 |
| Description: | Tracker inoperative because hit by lightning. Diffuse and direct normal shortwave irradiance incorrect during this time. LW downwelling data can have higher uncertainties under direct sun. Problem described in instrument DQR D090129.1 |
| Suggestions: | Don't use SW direct or diffuse data during these time periods. If "source_BestEstimate_down_short_hemisp" is 0, don't use Best Estimate GSW data. Note that fewer quality checks can be applied accurately to the BestEstimate data. |
