I used to download Merra2 data using from merra scraping script, it fetches from opendap, recently i am getting 32kb netcdf file which is a error file, earlier i used to get the 18kb which has data. What might be the possible cause, is there any changes with authentication, login, change in format h...

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?

Re: PM 2.5 unit conversion from kg/m3 to kg/m2
Based on your answer, i need to download HLML from tavg1_2d_flx_Nx (M2T1NXFLX) and multiply with the SSSMASS.

I have data from merra 2 for sea salt mass concentration, the unit is kg/m3 , i need it in kg/m2 for my application. I like value for length scale which needs to multipled to it. How to find a length scale for specific location.
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...
Merra2
I like to download some data from Merra2, i found a script from github to download data(https://github.com/emilylaiken/merradownload) also found Giovanni.
Which is better Giovanni or the script, what is the difference between the two.
