Here is a list of updates that were considered when this was last reviewed in 2010 (2, 4 and 5 are included in the [[GEOS-Chem v8-03-01|v8-03-01]] update):

|Account for absorption in the 300-500 nm range by OC, which may be greater than presently treated.  Currently we have OC ss albedo in this range being > 0.95, though it may be lower than 0.85.

|Expand Mie table to include more wavelengths.  Most literature values compare at 500 or 550 nm. Current GC lookup table includes 400, then 600.  A wider range is also necessary for integrating to get total SW flux; something greater than 1500 perhaps?

|Treat the radius of hydrophylic organic aerosol similar to that of sulfate.  This is based on observations that organic aerosol and sulfate are often internally mixed.  Should we consider something similar for black carbon?
