Raw spectra measurements of scattered sunlight collected using a MAX-DOAS (Multi-Axis Differential Optical Absorption Spectroscopy) instrument in the austral summer of 2016/17 during the Antarctic Circumnavigation Expedition (ACE).

Data file(s): LiveInfo_DDDhhmmss.WWW
where DDD is the day of the year and WWW the central wavelength of the measured spectrum in the ultraviolet or visible region

Loop: cycle number
Filename: DDDHHMMSS, where DDD is the day of year and HHMMSS is the time of the measurement [UTC]
Elevation: elevation viewing angle [degree]
Pitch: inclination of the vessel about an axis that is perpendicular to both the local vertical axis and the nominal forward motion direction of the platform [degree]
Roll: inclination of the vessel about an axis that is perpendicular to the local vertical axis and is coplanar with the nominal forward motion direction of the platform [degree]
Et: parameter not used or recorded within these data files. Default value of 1 is not meaningful
