There are some questions about the parameter synthesis of pm2.5

Thank you very much for the help you have provided, I have recently encountered a new problem, the problem is this, I have downloaded the nc data from the following dataset: MERRA-2 tavgM_2d_aer_Nx: 2d,Monthly mean,Time-averaged,Single-Level,Assimilation,Aerosol Diagnostics V5.12.4 (M2TMNXAER). And ...

Re: Magnitude and Unit of PM2.5, MERRA-2: Conversion Necessary?

Thank you for your serious answer, it is very helpful for my research. In the last sentence of your answer you mentioned that you don't understand the meaning of the phrase: "Can I use this month's data?". This sentence means can I utilize the following dataset: MERRA-2 tavgM_2d_aer_Nx: 2d...

Re: Questions about data synthesis

Sorry, I am a beginner. I want to calculate the aerosol optical thickness (AOD) of a region. In addition to that, I want to calculate the regional distribution of black carbon aerosol, sand aerosol, organic carbon aerosol, sea salt aerosol and sulfate aerosol in this region. I see that there are man...

Questions about data synthesis

I have been able to extract the parameter data in the merra2 dataset, but I don't know how to use these parameters to synthesize some data, for example, I want to synthesize the data of sulfate aerosol or black carbon aerosol in a certain area, please ask if there is any calculation formula or refer...
