Online visualization of the MYSTIC simulation
The following two pictures show the model domain which we used in the
MYSTIC calculation (left) and an animation of a number of photons.
In backward mode the photons start at the location where we want to know the
irradiance (Weissfluhjoch) and are traced until they leave at
top-of-atmosphere towards the sun.
Diurnal variation of integrated solar irradiance (low-res forward calculation)
Global (surface-parallel) solar irradiance
Direct (surface-parallel) solar irradiance
Diffuse downward (surface-parallel) solar irradiance
Upward (surface-parallel) solar irradiance
