Overview:
===============================================================================

netCDF file containing GEIA NH3 emissions for year 1990.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%% IMPORTANT NOTE: These emissions are mostly obsolete now
%%%%%                 and should be replaced at the same time
%%%%%                 that files in v2014-07 are replaced.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

This directory contains GEIA NH3 emissions file v2014-07/NH3_geos.4x5.nc
regridded to 2x2.5 using conservative regridding. A 2x2.5 file exists
in the v2014-07 directory but it does not contain the same emissions totals
as the 4x5 file and therefore should not be used. The file in this directory
should be used instead for consistency.
