This 1-year benchmark simulation was approved by HEMCO developer Christoph Keller and the GEOS-Chem Steering Committee on 01 Dec 2014.

Comments about the 1-year benchmark v10-01e
Jeff Pierce wrote:
- The carbonaceous aerosols have definitely changed since the last benchmark, but now OCPI over tropical forests is less than 10% of the OCPI pre-HEMCO (page 35 of the ratios). Can you confirm that the 0.1*monoterpenes is being added to OCPI as it was pre-HEMCO?
Melissa Sulprizio responded:
- I found an error in the MEGAN emissions. In the HEMCO configuration file, we have MEGAN_SOA turned on by default because HEMCO knows to ignore the SOA species if we are not running a SOA simulation. However, with MEGAN_SOA turned on, we don’t execute the part of the code where we add 0.1*monoterpenes to OCPI. Therefore, as you noted, we see lower OCPI concentrations over tropical forests. Turning MEGAN_SOA off fixes this problem.
Shiliang Wu wrote:
- The O3 profiles show some large increases (up to 30ppb or more) in Jan for certain locations, such as Uccle(51), Hohenpeissenberg(48), Kagoshima(32), Shanghai(31), etc. - these don't look to be due to emission change, so I wonder what's causing this?
Christoph Keller wrote:
- There were two open questions regarding the 1-yr benchmark (at least to my knowledge):
- 1. The ozone ‘blob’ forming over Europe in January
- 2. The much lower concentration of NITs and SO4s in v10-01e compared to v10-01c.
- I think I have an explanation for both points, and I would argue that the new code makes more sense physically:
- 1. The ozone blob is actually a good thing as it removes an issue that was introduced in v9-02r. As Melissa pointed out to me, ever since v9-02r we have been seeing a drastic decrease of ozone over Europe (and to a lesser extent East Asia) in January. This was because PARANOX could produce - under low O3 conditions - incredibly high O3 deposition values (division of a high number by a very, very small number). This would basically create a black hole for ozone at the surface that would then remove more and more ozone from the entire column. Melissa did a number of sensitivity studies where she ran v10-01c with and without PARANOX, and those plots show this effect very nicely. The new code does not allow such a behavior anymore, which explains the higher ozone concentrations in January compared to v10-01e.
- 2. NITs and SO4s are closely linked to sulfate chemistry and thus alkalinity. Alkalinity is directly obtained from the total mass of emitted sea salt aerosol, e.g. we approximate alkalinity = SSA. Since SSA is a 2D field but alkalinity is 3D, the sea salt aerosol need to be distributed vertically. In the old code, alkalinity was set to the total mass of emitted sea salt aerosol for every grid box that was below the PBL (zero otherwise). In other words, if the PBL was at level 11, the integrated alkalinity over this column was 10 times higher than the total mass of emitted sea salt aerosols in the same column. I found that not very realistic and therefore changed the alkalinity calculation so that it takes into account the fraction of the PBL. I also checked in with Fabien Paulot who has been working on this and he also thinks that this is the better way of doing it. After all, it ensures that the total alkalinity equals the total amount of emitted sea salt aerosols. This explains the much lower values for NITs and SO4s that we see in v10-01e compared to v10-01c.

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)
--Bob Y. 13:15, 30 May 2014 (EDT)
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.
