In this dataset we provide hyper-spectral fields of visible and near infrared cloud top radiance observed by the AISA Eagle instrument. This instrument was part of the HALO-(AC)³ campaign in March/April 2022. The dataset contains hyperspectral fields of visible and near infrared cloud top radiance observed. AISA Eagle uses a single-line push broom sensor comprising 1024 across-track pixels, it captures measurements of 2D fields of upward radiance across 504 channels spanning wavelengths from 400 nm to 993 nm. Featuring a 36.3° field of view (FOV), it achieves a spatial resolution below 1 meter for targets positioned 1 kilometer away. Throughout HALO-(AC)³, it operated at a frame rate of 20 Hz.
