What do you want?

• Refractive indices, size distribution (log-normal mode parameters) etc

OR

Pre-calculated (from Mie code) extinction, single scattering albedo, asymmetry parameter and phase function

Note, some issues with how we deal with RH depending on choice above

Aerosol typesComponents

planned• Ammonium sulphate

(different size modes?)

• Ammonium nitrate• Soot• Mineral dust• “Organics”• Sea salt• Volcanic

Types planned• Desert• Maritime• Biomass• Urban?• Rural continental?• Polluted continental?

+???

Timescales

• Original deliverable Jan 2010 But…

Will try to get this done by September 2009 (i.e. pre-leave). However, will have to scale back types etc a little due to needing to work on aircraft side too….
