Simulated top-of-atmosphere (120 km) downward and upward solar and thermal-infrared irradiances and ice cloud optical thickness; calculated solar, TIR and net cloud radiative effect. Simulated with ice crystal properties for aggregates, droxtals, and plates based on Yang (2013).

This dataset consists of three .nc files for ice crystal shapes of aggregates, plates, and droxtals. The files include ice cloud optical thickness \(\tau\) (550nm), the simulated upward and downward irradiances \(F\) at the top-of-atmosphere (with and without the presence of the ice cloud), and the calculated ice cloud radiative effect \(\Delta F\) (solar [0.3-3.5 \(\mu\)m], thermal-infrared [3.5-75 \(\mu\)m], and net). The data set allows the user to extract \(\Delta F\) values for their parameter combinations. The available cloudy and cloud-free irradiances further allow to calculate the cirrus radiative effect (RE) by scaling the 'cloudy' RE with the required cloud cover. This serves as a first-approximation because, as 3D effects are neglected.
