MetVed v.2.0. Improvement and update of the MetVed emission model for residential wood combustion
Grythe, Henrik; Lopez-Aparicio, Susana (NILU report;19/2020, Research report, 2020)This report presents the update of the MetVed-model (Grythe et al., 2019). Among the updates are new emission factors and several new species that include climate gases (CO2, CH4 and N2O). There is now a new parameter that ... -
Model development for high-resolution emissions from residential wood combustion
Lopez-Aparicio, Susana; Grythe, Henrik; Vogt, Matthias (NILU report;32/2018, Research report, 2018)In this report, we describe the MetVed model developed to estimate emissions from residential wood combustion (RWC) at high spatial-temporal resolution. The model uses a downscaling method approach, which builds on bottom-up ... -

The MetVed model: development and evaluation of emissions from residential wood combustion at high spatio-temporal resolution in Norway
Grythe, Henrik; Lopez-Aparicio, Susana; Vogt, Matthias; Vo, Dam Thanh; Hak, Claudia; Halse, Anne Karine; Hamer, Paul David; Sousa Santos, Gabriela (Journal article; Peer reviewed, 2019)We present here emissions estimated from a newly developed emission model for residential wood combustion (RWC) at high spatial and temporal resolution, which we name the MetVed model. The model estimates hourly emissions ... -
