Metrics | |
Global mean OH (from log file): | 13.3152237747292 x 105 molec/cm3 |
Methyl chloroform lifetime: | 4.7044 years |
Did either of these change by more than 5%? | No |
At the SURFACE, list all species that changed by 10% or more: |
PAN (downwind of South America), ALK4 over oceanic basins, ISOP downwind of South America, MEK tropics, MVK, MACR (downwind of South America), PMN, PPN, PRPE, N2O5, DMS |
Comments on SURFACE differences: |
Sort of makes sense. Changes are in regions that are NOx starved (South America) or cold (the loss from GLPAN will be greatest). Changes are small overall and almost always negative. The changes for DMS are relatively large (10-20% decrease) |
At 500 hPa, list all species that changed by 10% or more: |
ALK4, ISOP, MEK, MVK, MACR, PRPE (large changes in polar regions > 20%), DMS |
Comments on 500 hPa differences: |
Changes are generally bigger than at the surface (temperature dependence of GLPAN) |
In the ZONAL MEAN differences, list all species that changed by 10% or more: |
ISOP (but at high altitude and in polar regions), ALK4 in polar regions, MEK, MVK, MACR, PMN, PRPE |
Comments on ZONAL MEAN differences: |
Small changes overall (in an absolute sense). DMS has the largest change. |
In the EMISSION RATIO maps, list all species that changed by 10% or more: | |
Comments on EMISSION RATIO differences: | |
