Field measurements of soil carbonyl sulfide fluxes

During my years in the graduate school, I have participated in field measurements of soil carbonyl sulfide fluxes at these sites.

  1. UC Stunt Ranch Natural Reserve, Santa Monica Mountains, CA

    This site features a mediterranean-type oak woodland. The field campaign ran from March to May, 2013. We measured soil fluxes of carbonyl sulfide, CO2, and water using dynamic soil chambers.

    The data set is available at For a description of the key findings, see Sun et al. (2016) JGRB.

  2. Hyytiälä Forest, Finland

    This site features a Scots pine forest, with mostly young stands established after 1960s. The field campaign to measure soil fluxes of carbonyl sulfide, CO, CO2, and water ran from June 2015 to November 2016, excluding winter months. The data set from 2015 has been published with Sun et al. (2018) ACP, and can be downloaded at

  3. San Joaquin Freshwater Marsh, Irvine, CA

    Data coming soon.

  4. La Selva Biological Station, Costa Rica

    Data coming soon.

Soil carbonyl sulfide flux model code (archived)

The repository contains legacy code of a model that simulates soil–atmosphere flux of carbonyl sulfide. The model solves a 1-D diffusion–reaction equation of carbonyl sulfide in the soil column. There are two implementations of the model, one in IDL (a proprietary high-level scripting language) and the other in Python 3.

Development of the model has been discontinued due to lack of funding support. However, I would be happy to help if you are interested in implementing this model in your favorite earth system models.
