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

This data directory contains updated annual and monthly fossil fuel CO2 
emissions and scale factors from ODIAC. Note that other files required
for the CO2 fossil fuel simulation (Aviation_SurfCorr_SclFac.1x1.nc,
TIMES_diurnal_scale_factors.nc, TIMES_weekly_scale_factors.nc) have not 
been modified and are still available in the v2015-04/FOSSIL/ directory.
