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

This directory contains the same monthly emission fluxes of organic iodine
compounds (CH3I, CH2I2, CH2ICl, CH2IBr) from Carlos Ordonez as in
directory HEMCO/IODINE/v2017-09, but with latitudes shifted to be symmetric
around 0 and offset from the poles. The original files in v2017-09 are 1x1
with latitudes [-90,-89,...,88,89] while th enew files are 1x1
with latitudes [-89.5,-89,...,88.5,89.5].
