[BUG/ISSUE] Issue with offline dust emissions -- use online dust until further notice

[msulprizio]

Randall Martin and Jun (@Jun-Meng) have reported the offline dust emissions currently used in GEOS-Chem may be problematic. The primary issue is that these emissions accidentally included experimental code without a clear reference. The recommendation is to therefore use online dust emissions (i.e. the DustDead extension) until further notice. In GEOS-Chem 13.2.0, we will propose to update the online dust emissions to the scheme described in Meng et al. (in review). Once the online emissions have been updated and gone through the benchmark validation process, we will generate new high-resolution offline emission files.

In commit eb97d0b, OFFLINE_DUST is set to false and DustDead to on by default. A note has also been added to HEMCO_Config.rc telling users to avoid using offline dust emissions until further notice. This will be included in 13.0.1.

Is there an update on this issue and/or a timeline for the reactivation of offline dust? [tagging @lizziel ]

EDIT: Never mind! I see from #816 that this is now resolved.

Hi, @msulprizio ! I'd like to know whether the online dust emission scheme was updated according to the scheme described in Meng et al. (a high-resolution dust source function and global annual dust emission strength of 2000 Tg yr−1 rather than 909 Tg yr−1 ) for the current version of GEOS-Chem (e.g., v14.x.x)?
