**Experiment title 🔔:** Fixing DMS ancillary files in ACCESS-AM2 simulations

**Summary 🔔:**  
I have several runs (4) in which I had assumed that the DMS climatology followed that of GA7.1. I have recently found that it was actually using an outdated climatology. I would like to re-run these simulations with the correct climatology. The runs are exploring aerosol sources in the ACCESS-AM2 model, which are significantly underestimated. They include a control run, turning on boundary layer new particle formation and primary marine organics, and enhancing the sea spray flux. See post here: [ACCESS-CM2/AM2 DMS Ancillary file error](https://forum.access-hive.org.au/t/access-cm2-am2-dms-ancillary-file-error/2129)  
**Scientific motivation:**  
Improve aerosol representation in ACCESS-AM2  
**Experiment Name 🔔:** dg657\_control  
**People 🔔:** Sonya Fiddes  
**Model:** ACCESS-AM2  
**Configuration:**  
**Initial conditions:**  
**Run plan:** runs are 6 years, 4 x experiments, 2014-2019.  
**Simulation details:** Hope to start ASAP  
**Total KSUs required 🔔:** 80KSUs per simulation = 320KSUs  
**Total storage required 🔔:** No storage needed  
**Outputs:** Lots  
**Restarts:**

@heidi @cnf @Yi_Huang

Any objections? Simulations are ready to go, for inclusion in a publication that is pretty much fully drafted

Sounds good to me.

Cheers, Yi
