| Performed a test of the instrument under different azimuth angles to assess possible issues with the polarisation properties. To do this, I ran the instrument around all azimuth angles (10 degree increments) pointing vertically (i.e. zenith). Conditions were clear blue sky. So, there should now be data between 2018-02-19 06: | 50 UTC that rotates between azimuth -180 to +180 (at +90 elevation) that we can use to assess these polarisation properties in the field. |
| Also note: | 07 UTC; I wanted to do a calibration but clouds came over so I stopped. |

So, there should now be data between 2018-02-19 06:42 and 2018-02-19 06:50 UTC that rotates between azimuth -180 to +180 (at +90 elevation) that we can use to assess these polarisation properties in the field. Also note: No data was collected between about 2018-02-19 05:55 and 2018-02-19 06:07 UTC; I wanted to do a calibration but clouds came over so I stopped. |
