Summary:
===============================================================================

In GEOS-Chem v9-01-01, the following updates were made that impact the 
emissions of lightning NOx:

  (1) Bug fix for incorrect cloud-top-height determination
  (2) Addition of updated vertical release profiles (cf. Ott et al 2010)
  (3) Removal of obsolete options from the source code (lightning_nox_mod.f)

For detailed information about these updates, please see the document prepared
by Lee Murray (ltmurray@seas.harvard.edu):
