Additional or summary comments: | Removal of biomass burning updates
After the 1-month benchmark for v11-02a, the GCSC decided we should remove the code updates for vertically distributed biomass burning emissions (see this wiki post for more details). In addition, after the 1-year benchmark v11-02a-Run0, the GCSC asked that we comment out the partitioning of NOx biomass burning emissions directly to PAN and HNO3 (see this wiki post for more details). An unofficial 1-month benchmark was run for v11-02a to evaluate the model changes with the biomass burning injection height updates removed. The plots for that run may be viewed at: Results from our v11-02a benchmark using the GNU Fortran Compiler In order to evaluate the performance of GEOS-Chem using the the free and open source GNU Fortran compiler, we performed an additional 1-month benchmark for v11-02a. For this additional benchamark, we used GNU Fortran v6.2.0 to compile GEOS-Chem instead of our usual Intel Fortran Compiler version 11.1.069. For more details, see this post on our GNU Fortran compiler wiki page. Summary: The benchmark using GNU Fortran yielded essentially identical results to the benchmark using Intel Fortran. This is very encouraging, as it will allow GEOS-Chem development to take place on computational platforms that do not have proprietary compilers (such as Intel Fortran or PGI Fortran), which can be prohibitively expensive to purchase. | ||||||||||||||||||||||||||||||||||||||||||||||
