Observations of the broadband solar and terrestrial, upward and downward irradiance were made by the Broadband AirCrAft RaDiometer Instrumentation (BACARDI) onboard the High Altitude LOng range research aircraft (HALO) during the HALO-(AC)³ campaign in March and April of 2022. BACARDI consists of two sets of Kipp and Zonen instruments - pyranometers (CMP-22) for the solar range (0.2 - 3.6 μm) and pyrgeometers (CGR-4) for the terrestrial range (4.5 - 42 μm). The data is provided at a measurement frequency of 10 Hz and has been corrected for dynamic temperature effects. More detailed information can be found in Ehrlich et al. (2023, doi:10.5194/amt-16-1563-2023). Observations of the downward solar irradiance are provided with and without a correction for the aircraft attitude, which corresponds to cloud-free and cloudy conditions above the aircraft. Furthermore, simulated, cloud-free downward solar irradiances are also given as a reference.
