− | * | + | *HEMCO now reads all input data from netCDF files and automates the emission calculation process. Specifically, all input data (base emissions, scale factors, masks) are regridded onto the simulation grid before any data manipulation is performed. This fact alone may cause local emission differences on the order of 10%, e.g. for GFED-3 emissions over some areas in Africa. |
− | *The difference in ISOP and related biogenic species can be attributed to the fact that the MEGAN biogenic emissions in HEMCO were modified to only use the current day's leaf area index (LAI). In v10-01d and prior versions, the LAI was interpolated from the previous and current months. | + | *NO emissions over the US are approx. 25% higher compared to v10-01d. This is partly because of the regridding artifact mentioned above and partly because the NEI2005 emissions have now been lumped into the surface level. In v10-01d, NEI-2005 input data was distributed over 5 levels but only the lowest 2 were used for emission calculation. |
− | *Differences in | + | *The difference in ISOP and related biogenic species can be attributed to the fact that the MEGAN biogenic emissions in HEMCO were modified to only use the current day's leaf area index (LAI). In v10-01d and prior versions, the LAI was interpolated from the previous and current months. This change may be responsible for the large relative change of e.g. ISOP above 60 degrees N. Absolute concentrations are very small in the areas where relative changes are large. |
− | * | + | *Differences in DMS may be attributed to the fact that HEMCO uses a new updated air-sea exchange module. The air-sea exchange module centralizes this computation and uses the same parameterization scheme for all compounds. (In v10-01d and prior versions, this computation was repeated in several locations in the code.) The new air-sea exchange module seems to give lower DMS concentrations than the prior code. |
− | + | *The C2H6 differences are due to biofuel emissions over Europe, North America and Asia, which were not taken into account in v10-01d. This effect is most obvious in Asia, where biofuel emissions are highest. | |
− | *SO2 | + | *SO2: HEMCO uses a different volcanic input file (still the same Diehl inventory) and a new vertical regridding scheme, which may be responsible for the SO2 differences. |
− | + | *HEMCO carries only BC and OC, and the separation into hydrophobic/hydrophilic parts is done outside of it. As a result, biogenic OC emissions computed by MEGAN become split into OCPI and OCPO. | |

*GEOS-Chem v10-01d and prior versions use a klunky emissions interface. There was a significant amount of hardwiring, especially in the application of scale factors and masks. In v10-01e, HEMCO has completely replaced this legacy emissions interface. We have tried to replicate the emissions output r of v10-01d to the greatest extent possible. But in v10-01e+HEMCO, we have also brought in a couple of newer inventories (volcanoes, etc.) while also introducing a new vertical regridding scheme.

v10-01c
Because GEOS-Chem v10-01c was the version where we introduced the UCX chemistry mechanism, we performed two 1-month benchmark simulations:
- v10-01c_trop: 1-month benchmark with tropopsheric chemistry
- v10-01c_UCX: 1-month benchmark with UCX strat-trop chemistry (72 vertical levels)

Final recommendation for J-values
We were not able to include this final recommendation for J(HAC) and J(PAN) into the v10-01c_trop and v10-01c_UCX 1-month benchmarks. We will include these in the 1-year benchmarks for v10-01c.

Additional or summary comments: | We still need to determine what caused the changes in the MODIS LAI input files. As per our earlier discussion, we have put in an error trap in drydep_mod to make sure that the changes are only made for simulations using GEOS-FP and the Olson 2001 land map. |
