    Description:
    The file named "Raw_Reference+OIDU_Data.xlsx" contains both raw data from the Phenom 300 reference scientific measurements and raw data from measurements by the Icing Detection System (IDS) Optical Icing Detection Unit (OIDU) installed in the Phenom 300. Each tab of the file named "Raw_Reference+OIDU_Data.xlsx" contains data from a specific flight with the flight number in the tab. Each tab contains columns for measurement time (in seconds of the UTC day), 905 nm OIDU signal (in counts), 1525 nm signal (in counts), 1635 nm signal (in counts), flight altitude (in ft), air temperature (in degrees C), liquid water content -LWC (in g/m^3), total water content -TWC (in g/m^3), ice water content -ICW (in g/m^3), and median volume diameter -MVD (in micron)., The file named "Raw_MRU_Data.xlsx" contains raw data from measurements made by the microwave resonator unit (MRU). The various columns contain data from engineering measurements and icing detection measurements. The data scientific relevant are in column A -the time stamp in UNIX time, column B -the time stamp in seconds of the GMT day, column G -the peak resonator frequency (Hz), and column H -the resonance quality factor (non-dimensional)., and The file named "Appendix-C-O_Data_Explained.xlsx" contains processed data from measurements by the Phenom 300 reference scientific measurements and processed data from measurements by the Icing Detection System (IDS) Optical Icing Detection Unit (OIDU) installed in the Phenom 300. As explained in Renno et al. (2025), the raw data was reduced by removing data points reported to contain measurement errors (identified by the NAN code in the data) and in-cloud measurements in which TWC ≤ 0 or MVD ≤ 0 before being analyzed. Each data column is described in the first tab.
