############################################################################
This folder contains FOUR sets of files:
1. Emissions for DRF (Direct Radiative Forcing)
2. Emissions for NPP (Net Primary Productivity)
3. Radiative fields for DRF
4. Deposition fields for NPP

############################################################################

1. Emissions for DRF
Files: DRF_EMISSION_CENTRAL.nc and DRF_EMISSION_HIGHOXIDE.nc

Coverage: Global
Year: 2010
Resolution: 1x1 degrees latxlong
Format: netCDF
Units: kg/m2/s

Variable nomenclature: 
In each of the variable name: FINE refers to Fine (PM1) and COA refers to Coarse (PM1-10) aerosol size, respectively. 
HEM, ILL, KAO, and MAG refer to hematite, illite, kaolinite, and magnetite, respectively.

Hence, FINE_HEM would refer to hematite emissions in the PM1 size fraction.

Variable list: 
FINE_HEM
FINE_ILL
FINE_KAO
FINE_MAG
COA_HEM
COA_ILL
COA_KAO
COA_MAG
------------------------------------

2. Emissions for NPP
Files: NPP_EMISSION_CENTRALANTHRO.NC and NPP_EMISSION_HIGHANTHRO.nc

Coverage: Global
Year: 2010
Resolution: 1x1 degrees latxlong
Format: netCDF
Units: kg/m2/s

Variable nomenclature:
In each of the variable name: Fine refers to Fine (PM1) and Coar refers to Coarse (PM1-10) aerosol size, respectively. 
SolFe and InSolfe refer to initially-soluble and insoluble anthropogenic iron emissions, respectively.

Hence, Coar_Insolfe_Comb refers to insoluble iron emissions in the PM1-10 size fraction.

Variable list: 
Fine_Solfe_Comb
Fine_Insolfe_Comb
Coar_Solfe_Comb
Fine_Insolfe_Comb
------------------------------------

3. Radiative fields for DRF
Files: DRF_RAD_FIELD_ALLMINERALS_2010.nc, DRF_RAD_FIELD_ONLYOXIDE_2010.nc, and DRF_RAD_FIELD_HIGHOXIDE_2010.nc
Coverage: Global
Year: 2010
Resolution: 0.96x1.25 degrees latxlong
Format: netCDF
Units: W/m2

Variable nomenclature:
This file has multiple variables, but to calculate the DRF, only two are required: NTOA and FSNTOA_d2
FSNTOA is the net top-of-atmosphere solar flux in the model

Variable list:
FSNTOA
FSNTOA_d2
------------------------------------

4. Deposition fields for NPP
Files: NPP_DEPOSITION_CENTRALANTHRO.nc and NPP_DEPOSITION_HIGHHRO.nc

Coverage: Global
Year: 2010
Resolution: 0.96x1.25 degrees latxlong
Format: netCDF
Units: kg/m2/s

Variable nomenclature: 
This file has multiple variables, but only two represent the anthropogenic soluble iron deposition, a value required to further calculate NPP.
FEANSOLDRY and FEANSOLWET represent the dry and wet anthropogenic soluble soluble iron deposition, respectively.

Variable list:
FEANSOLDRY
FEANSOLWET
