|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?

=== Organic Aerosol Density (v.10-01) ===
<span style="color:green">'''''This update was validated with [[GEOS-Chem_v11-01_benchmark_history#v11-01b|1-month benchmark simulation v11-01b]] and [[GEOS-Chem_v11-01_benchmark_history#v11-01b-Run0|1-year benchmark simulation v11-01b-Run0]]. This version was approved on 19 Aug 2015.'''''</span>
The organic aerosol density (1800 kg/m3) for calculating aerosol optical depth in aerosol_mod.F, based on Hess et al. (1997), is outdated and not representative of organic aerosols. The value is for a generic water soluble aerosol that could include sulfate, nitrate, SOA etc. Instead, we suggest GEOS-Chem users replace this with a density of 1300 kg/m3. There are numerous references that corroborate this value, or a value between 1200-1400 kg/m3. There are too many to list, but see for example p. 5174-5175 of Hallquist et al., ACP, 2007.
To make the change in aerosol_mod.F simply replace '''MSDENS(3) = 1800''' with '''MSDENS(3) = 1300''' in the RDAER subroutine. This leads to a 40% increase in organic carbon AOD.
Update by Eloise Marais (Harvard) and Melanie Hammer (Dalhousie).

=== Sedimentation of stratospheric aerosols ===
<span style="color:darkorange">'''''This update is slated for inclusion in [[GEOS-Chem v11-02]].'''''</span>
'''''Daniel Jacob wrote:'''''
:An issue has come up with our treatment of stratospheric aerosols. Seb Eastham applies sedimentation to sulfate and BC aerosols in his UCX code but he does not apply sedimentation to other aerosol species nor is his sedimentation code used in other GEOS-Chem simulations. It would be good to have consistency across aerosol types and across simulations (tropchem, RnPbBe...).
