MERRA-2 60 minute (hourly) PM 10 ?

[alexkubiniec]

Is PM10 at 60 minute temporal resolution available via MERRA-2?

The description on this page suggest that it might be possible? https://disc.gsfc.nasa.gov/datasets/M2T1NXAER_5.12.4/summary

Specifically this text from the description:
"The total PM1.0, PM2.5, and PM10 may be derived with the formula described in the FAQs under the Documentation tab of this page."

However, when reviewing the MERRA-2 tavg1_2d_aer_Nx data, this specific file for example: "MERRA2_401.tavg1_2d_aer_Nx.20210702.nc4"
variables such as DU001 are not present.

Is it correct to assume based on the documentation and datasets:

1. PM10's highest temporal resolution is 3 hourly, and calculated from the inst3_3d_aer_Nv collection
2. PM2.5's highest temporal resolution is 1 hourly, and calculated from the tavg1_2d_aer_Nx collection
?

You are right by saying below
1. PM10's highest temporal resolution is 3 hourly, and calculated from the inst3_3d_aer_Nv collection
2. PM2.5's highest temporal resolution is 1 hourly, and calculated from the tavg1_2d_aer_Nx collection
