NOTE: the file pnoy_nox_hno3.geos5.2x25.prelim were regridded with only one day's worth of GEOS-5 surface pressure data. We will replace these files once we have the full year of GEOS-5 met field data processed and stored locally. For now these files are symbolically linked so that GEOS-Chem may read them. It may not make a huge difference, as this file contains stratospheric OH which is just used to make sure that stuff doesn't build up in the stratosphere (which is a kind of hokey algorithm anyway). In the GEOS-5 stratosphere, all of the levels above 176.93 hPa are fixed-pressure levels. 15 Feb 2007 Bob Yantosca bmy@as.harvard.edu
