Re: Merra2

Thanks for answering I didn't understand it. I searched in google and i got this (https://developers.google.com/earth-engine/datasets/catalog/NASA_GSFC_MERRA_flx_2) Here they have mentioned 60 m as HLML. From the Merra2 File specification(https://gmao.gsfc.nasa.gov/pubs/docs/Bosilovich785.pdf) I am ...

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

Apart from MERRA2, is there any other source where i can get chloride in terms of aerosols.

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?

Re: Corrosion

Hi Mike
Thanks for the reply
For chloride will you suggest to add all chloride bins or is there any tracer associated with it.
and do you think scaling will have bigger influence?

According to ISO 9223-2012, we have a formula for R(Corrosion), in that formula we have to include chloride and sulfate. From MERRA, which parameters i need to consider (https://gmao.gsfc.nasa.gov/global_mesoscale/dyamond_phaseII/docs/DYAMOND_PHASEII_4km_Ocean_6km_Atmosphere_FileSpec.pdf) We have ma...

Re: Regarding bins in MERRA

we have sea salt wet deposition from Bin 001 to Bin 005, what does that 5 bin represent.
SSWT001 to SSWT005
