NOTE: Only PEM-Tropics-B, SONEX, POLINAT-2 and PEM-Tropics-A
have bee re-processed to include additional species. For the other
data sets, the old files have just been re-written in the new format.
They will be re-processed as well for additional species.
Species file labels
Some abbreviations for species labels have been used in the composite file names (also used in the Profile plots above). File headers give full variable names:File Formats
- pannox: PAN/NOx
- hno3nox: HNO3/NOx
- h2o2ch3ooh: H2O2/CH3OOH
- c3h8c2h6: C3H8/C2H6
- nono2: NO/NO2
- noday: NO when SZA<90deg
- rhi (rhw): Relative Humidity with respect to ice (water)
For both 5x5 grids and profiles, data files start with a header indicated by '#' in the first column. The header information is in the specified order:5x5 Grids:
