unit conversion of MERRA2 variabless

I need to use Sea Salt Surface Mass Concentration (SSSMASS). it is with unit of kg m-3, i need it in the format of kg/m3day
For that should i just multiply by 24 or divide by 24?

Merra2

Hi I am not a chemistry expert, i need your support on unit conversion. Sea Salt Surface Mass Concentration - PM 2.5 is in Kg/m3 (Volumetric method), i need to convert into mg/m2 (Deposition method). For Example if i get 9.95 * 10^-9 kg/m3 as Sea Salt Surface Mass Concentration, what is the value in...

Re: Corrosion

Hello
My purpose is to find how much chlorine is deposited into the wind turbines.
consider wind turbine height is 200m from the ground.
For that purpose, can i use SSSMASS25, do i need to scale the value or directly use it.

Re: Corrosion

Also what is SUSD002?
Can Sulfate mass concentration be skipped?
Could you tell something about Sulfate Convective Scavenging, what does that mean, any referral doc?
