Dear @ganluoasrc

I am currently understanding the code related to sea salt. The code is contained in apm_init_mod.F. However, I am not clear on how the bin sizes for sea salt are determined. Additionally, I am curious about why YVRAT is needed, why is DR calculated this way? and the meaning of DR.

The file apm_init_mod.F should be a necessary one, but when I used the command：'gdb gcclassic' and 'b apm_init_mod.F:1404', it did not pause at line 1404 in the apm_init_mod file.

Thank you for your assistance.

Best regards

These codes were used to calculate number size distribution based on aerosol microphysics shown in Seinfeld&Pandis textbook (2006). DR is the width of each bin.

Do not know what 'gdb gcclassic' and 'b apm_init_mod.F:1404' mean.
