[PPS06-P07] Examination of potential microphysical drivers of NIR emitted radiance variations on the Venus night side
Keywords:Venus, Akatsuki, Meteorology, Atmosphere
In a separate work, I had shown that plausible changes in microphysical properties produce observable variations in the distribution of the cloud mass and cloud particle sizes. Most notably, a two-regime quasi-steady state cloud was found in the simulations. The most notable difference between the two regimes was the presence and absence of a 1-2 km thick cloud layer near cloud base. This layer bears some similarity to the intermittently observed lower cloud deck between 48-50 km that is believed to be responsible for much of the observed NIR radiance emission on the night side of Venus. Here, I calculate the radiance variations that these changes can produce, specifically considering the spectral ranges observable using the Akatsuki IR2 camera and its associated filters.
