Feel free to contact Fang Li (lifang@mail.iap.ac.cn) and Sam Rabin
(sam.rabin@gmail.com) with any questions about the dataset, whether related to content,
access, processing, etc.

File naming conventions:

SPECIES.zip:
These archives contain NetCDF-4 files (see below) of each species of emissions as
simulated by each model (see Table 1).

NetCDF-4 files in archives:
Archives contain files RESOLUTION/MODEL_SPECIES_RESOLUTION.nc4. Names follow the
following convention:
    - MODEL: Model name (see Table 2)
    - SPECIES: Element or molecule (Table 1)
    - RESOLUTION:
        - orres (original spatial resolution of model) 
        - 1deg (one-degree resolution)
Variable femis in NetCDF-4 files gives the total fire emissions of the species in
question, with units g/second/m2. Temporal resolution and extent vary among models, as
do spatial resolution and extent in orres (original-resolution) files (Table 2).

Note that femis is saved in single-precision floating-point format, but in some models'
files contains an attribute _FillValue that may cause it to be read as double-precision
(as occurred in MATLAB during quality assurance testing).
