Voyage: IN2018_V01       [details]
Subject: Polarisation calibration
When: 2018-02-19 07:19:18 UTC

- entered into Elog/Everlog as 2018-02-19 07:19:18
Log: Atmospherics in2018_v01
Equipment: MiniMPL

Equipment: MiniMPL [view]
Position: Latitude: -53.62983 Longitude: 142.98017

- entered into Elog as 53 37.79 S, 142 58.81 E
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.

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 06:42 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.
