Short summary

Severe drought stresses vegetation and causes reduced emission of isoprene. We study the impact of including a new isoprene drought stress (y_d) parameterization in NASA GISS ModelE called DroughtStress_ModelE, which is specifically tuned for ModelE. Inclusion of y_d leads to better simulated isoprene emissions at the MOFLUX site during the severe drought of 2012, reduced overestimation of OMI satellite ΩHCHO (formaldehyde column), and improved simulated O₃ (ozone) during drought.
