General Algorithm

1. Map aerosol data to model grids
   • Map grid in longitude direction, lon from 0 to 355 deg resolution
   • Map grid in latitude direction, lat from 90n to 90s in 5 deg resolution

1. Determin the type of aerosol profile (kp) and scale hight for domain 1 (h1) to be used at this grid point.

1. Compute horizontal bi-linear interpolation weights

1. Do horizontal bi-linear interpolation on aerosol partical density (denn)

1. Do horizontal bi-linear interpolation on mixing ratios

1. Prepare to setup domain index array and effective layer thickness, also convert pressure level to sigma level to follow the terrain.

1. Call radclimaer() to calculate SW/LW aerosol optical properties for the corresponding frequency bands.
