A re-analysis of the entire data set was performed using continuous flights of data instead of subdividing flights into sections that were defined as “normal”, “disturbed”, and “no data” based on aircraft motion to avoid discontinuities and coverage gaps. The flight environment flag (FLTENVIRO) has been replaced with horizontal and vertical acceleration data (ACC_HOR, ACC_VER). Leveling corrections were interpolated through flight turns to maintain continuous data while avoiding the influence of turn effects. The re-analysis also includes general improvements to noise levels throughout the entire data set.
