Detailed Description

This subroutine retrieves biogenic emission factors and parameters based on the MEGAN2.1 framework. It provides plant-dependent emission capacities for various biogenic volatile organic compounds including: * Isoprene * Myrcene * Sabinene * Limonene * 3-Carene * T-β-Ocimene * β-Pinene * α-Pinene * 2-Methyl-3-buten-2-ol (MBO) * Methanol * Acetone * Other monoterpenes and sesquiterpenes

The parameters are provided for different vegetation functional types and include emission factors, light-dependent fractions, temperature coefficients, leaf age factors, and stress response parameters.

Parameters:

EMI_IND Input biogenic emissions index
LU_OPT Land use type option (0=VIIRS, 1=MODIS)
VTYPE Grid cell dominant vegetation type
EF Mapped emission factor (μg/m²/hr)
LDF Light-dependent fraction
BETA Empirical coefficient for temperature dependence of light-independent fraction
CT1 Activation energy (kJ/mol)
CEO Empirical coefficient
ANEW Empirical factor for new foliage
AGRO Empirical factor for growing foliage
AMAT Empirical factor for mature foliage
AOLD Empirical factor for old/senescing foliage
ROOTA Coefficient A for PFT dependent cumulative root depth fraction (m⁻¹)
ROOTB Coefficient B for PFT dependent cumulative root depth fraction (m⁻¹)
CAQ Coefficient for poor air quality stress
TAQ Threshold for poor air quality stress (ppm-hours)
DTAQ Delta threshold for poor air quality stress (ppm-hours)
CHT Coefficient for high temperature stress
THT Threshold for high temperature stress (K)
DTHT Delta threshold for high temperature stress (K)
CLT Coefficient for low temperature stress
TLT Threshold for low temperature stress (K)
DTLT Delta threshold for low temperature stress (K)
CHW Coefficient for high wind stress
THW Threshold for high wind stress (m/s)
DTHW Delta threshold for high wind stress (m/s)
