Re: Water vapour, ozone and aerosol data from MERRA-2 datasets

Hi Jimacker, Thank you very much for your info. I want the reanalysis data of AOT_550, total precipitable water vapor (in cm unit) and total ozone (in cm-atm) as input for a radiative transfer model for atmospheric correction. In this sense, do you know which ozone product from the MERRA-2 datasets ...

Aerosol type from satellite data

Dear EARTHDATA FORUM, I wonder how to interprete the Aerosol_Type_Land variable from the MYD04_L2 product? Generally, the aerosol types include maritime, continental, and etc. But I did not find such information from this variable. In addition, I want to know the aerosol type over a coastal water re...

Re: Water vapour, ozone and aerosol data from MERRA-2 datasets

Hi jimacker, Thank you very much for your reply. I am sorry for your confusion. Actually, I already got TO3, TQV, TOTEXTTAU, and TOTSCATAU data from the MERRA-2 datasets. But I was not sure how do these data correspond to the total amount of water vapour and ozone and AOT_550 which are the data I ne...

Satellite and airborne atmosphere and aerosol data

Hello!

For the satellite products of water vapour and aerosol optical thickness at 550 nm (AOT_550) data, is there any way to convert them to the data at the airborne altitude which is about 2 km?

Thank you in advance.
Kind regards,
Mengmeng.
