specMACS on (AC)3 campaign (March/April 2022)

general remarks

We had problems with the shutter of the VNIR camera which was closed during most of the flights. When the shutter was open is indicated below.

the specMACS instrument

specMACS is a hyperspectral imager, capturing one image line at a time. It is sensitive in the range of approx. 400nm to 2500nm and has a field of view of approximately 35°. During (AC)3 it is mounted on the HALO aircraft facing downwards and is accompanied by two 2D polarization resolving cameras. More information can be found in Ewald et al. (2016).
