~ Electricity sensors on each launch: i. Miniature Fieldmill Electrometer (MiniMill) & ii. Space charge sensor 

~ Radiosonde Type: GRAW DFM09 with XDATA interfacing protocol

~ Meteorological Data: available upon request

~ Retrieval software: GRAWMET 5, info@graw.de

~ Launching site: OSCM, Mindelo, Cabo Verde (16° 52' 40.3356'' N 24° 59' 43.746'' W)

~ Launching periods: June 2022 & September 2022


CSV contains:
column 1 - timestamp in UTC

column 2 - frametime of the sensors output in [ms]

column 3 - is_valid: state index for both sensors, when operational = TRUE, when not operational = FALSE

column 4 - space_counts: the raw Analogue-to-Digital (ADC) converter ouput in counts between 0 - 1024 for the space charge sensor

column 5 - space_state: space charge sensor state indicator for 0 -> normal operation, 1 -> calibration mode1, 2 -> calibration mode2, everything else -> not_valid

column 6 - mill_valid: minimill sensor state indicator for 0 -> non operational, 1 -> minimill works fine, everything else -> not_valid

column 7 - mill_counts: minimill sensor raw ADC counts between 0 - 1024

column 8 - mill_roll: the roll angle of the minimill sensor in [degrees*100]

column 9 - mill_pitch: the pitch angle of the minimill sensor in [degrees*100]

column 10 - mill_yaw: the yaw angle of the minimill sensor in [degrees*100]
