Current bug reports

These bug reports (listed on the HEMCO issue tracker) are currently unresolved. We hope to fix these in future HEMCO releases.

Masks cannot be applied to extensions

It is currently not possible to geographically tag emissions computed by HEMCO extensions in the same way that you would do for base emissions. We hope to add this feature into a future HEMCO release.

HEMCO may not recognize alternate spellings of units

If a unit string (e.g. kg/m2/s) read from a netCDF file matches the unit string listed under the SrcUnit column of the HEMCO configuration file, then no unit conversion will happen.

But if the unit string in the file is e.g. kg m-2 s-1 and the unit in the configuration file is kg/m2/s, then HEMCO detects this as a difference in units, and will try to apply an automatic conversion that is really unnecssary.

Therefore, we recommend not to rely on HEMCO’s automatic unit capability, and to specfiy all scale factors for unit conversions explicitly in the configuration file.
