LPX Dynamic Global Vegetation Model


The “Land surface Processes and eXchanges” (LPX: Kelley et al., 2014; Prentice et al., 2011) is a coupled process-vegetation model derived from the LPJ Dynamic Global Vegetation Model family (LPJ-DGVM: Sitch et al., 2003). The model describes dynamical vegetation and terrestrial biogeochemical processes, and how these processes interct with climate to control wildfire disturbance. The model has been developed and benchmarked for Australian fire regimes and fire adapted vegetation Kelley et al., 2014 - incorporating vegetative resistance and reliance adaptations common to Australia but important for the rest of the world - evolutionary adaptive bark protection and post-fire resprouting. The next stage of model development will focus on improving the simulation of fire dynamics for the rest of the world.


 

LPX model code


LPX model code is hosted on bitbucket using git version control. For access, please email.

Benchmarking system


The LPX benchmarking system links LPX converted outputs to the vegetation model benchmarking system. This is hosted on bitbucket and is openly available, but is new so email me if you have any problems.

All in one model run and benchmarking


This will be the ultimate all-in-one download and benchmark LPX system when finished. But is still under development. Give it a go though, it might work. For now, you will still need to contact me for access

Drought and resprouting plants


Many species have the ability to resprout vegetatively after a substantial loss of biomass induced by environmental stress, including drought. Many of the regions characterised by ecosystems where resprouting is common are projected to experience more frequent and intense drought during the 21st Century. However, in assessments of ecosystem response ...


Future Carbon in Australia


Climate projections show Australia becoming significantly warmer during the 21st century, and precipitation decreasing over much of the continent. Such changes are conventionally considered to increase wildfire risk. Nevertheless, we show that burnt area increases in southern Australia, but decreases in northern Australia. Overall the projected increase in fire is ...


LPX-Mv1


The Land surface Processes and eXchanges (LPX) model is a fire-enabled dynamic global vegetation model that performs well globally but has problems representing fire regimes and vegetative mix in savannas. Here we focus on improving the fire module. To improve the representation of ignitions, we introduced a reatment of lightning ...
