The RETRO inventory has improved temporal and spatial resolution and a more inclusive suite of speciated NMVOCs than many of the inventories currently employed. The new code allows for input of 13 anthropogenic VOCs, with a notable exception of acetone. In addition to the new input data from RETRO, this update fixes a bug associated with EPA/NEI CH2O emissions data.

Overview

Dear colleagues:

Updating the anthropogenic VOC emissions was identified as a priority update for GEOS-Chem at the previous GEOS-Chem Scientific and Users' Meeting. We have recently completed an update which allows RETRO anthropogenic VOC emissions to be read into the model. The RETRO inventory has improved temporal and spatial resolution and a more inclusive suite of speciated NMVOCs than many of the inventories currently employed. The new code allows for input of 12 anthropogenic VOCs, with a notable exception of acetone.

A description of RETRO and a comparison with the existing inventories is posted here. We have submitted this update to the GEOS-Chem support team for inclusion in the mainline model. It will remain an optional inventory (rather than the default) until there is some opportunity for comparison against observations.

Best regards,

Update 29 March 2011: The RETRO code was ported from v8-02-01 to v8-03-01 with minor changes. Please refer to the above documentation for details.

Update 20 May 2011: Updated documentation with full-chemistry simulation results and several minor edits.
