Broadband solar and terrestrial, upward and downward irradiance measured by BACARDI on HALO during the EUREC4A Field Campaign.

The Broadband AirCrAft RaDiometer Instrumentation (BACARDI) combines two sets of Kipp and Zonen broadband radiometer
measuring upward and downward irradiance in the solar (pyranometer model CMP-22, 0.2 - 3.6 μm) and terrestrial
(pyrgeometer model CGR-4, 4.5 - 42 μm) spectral range. The data from EUREC4A is of 10 Hz measurement frequency and corrected for
dynamic temperature effects. For the downward solar irradiance, data are providided with and without aircraft attitude correction
correconding to cloud-free and cloudy conditions above HALO. The radiometric calibrations of the pyranometer and pyrgeometer as secondary
standard are provided by the manufacturer and have an accuracy of about 1% for the pyranometer and 4% for the pyrgeometer.
The total uncertainty of the measured up- and downward irradiance is a combination of these different effects and depends on
the measurement conditions. Details are given in Zöger et al. (2021, in preparation).
