FireMIP

The Fire Model Intercomparison Project (FireMIP) is dedicated to strengthening the development of global fire models through a systematic comparison of current approaches and providing robust insights on global fire dynamics and impacts using an ensemble of coupled fire-vegetation models.

At the core of the project are standardized model simulations of modelling groups from all over the world and annual meetings where in-depth discussions, not only between modelers but also with experts in atmospheric chemistry, fire ecology, and groups generating observational datasets, are the drive and basis to refine the project goals. FireMIP is an international, unfunded initiative, started in the year 2014 and initially coordinated by Almut Arneth and Stijn Hantson.

Currently the group is performing revised historical simulations to revisit the performance of fire models over the historical period and extend analysis on the N-cycle-fire interactions, fire behaviour and impact, and the representation of extreme fires.

We are now moving towards a second phase where FireMIP simulations will be incorporated within the ISIMIP framework. This will facilitate the definition of protocols, preparation of input data, but also the data analysis, model comparison and data distribution. During this second phase we are planning to simulate fire activity under a set of the future climate and socio-economic conditions. The protocol for the future simulations is currently under development.

Background

Fire is a crucial Earth system process that impacts vegetation distribution and structure, carbon storage in terrestrial ecosystems and atmospheric composition. These impacts have consequences for biodiversity, ecosystem services, human health and climate. Unusually high and intense levels of fire activity have recently been seen across the globe from the Australia to the Amazon rainforest to the Arctic circle, often with catastrophic consequences for humans and ecosystems. These unusual fire activities show the need of fire models to provide insights on future changes and to support the adaptation to changes in fire regimes due to global change.

The main drivers of fire regimes on the global scale are climate, vegetation and humans, which are simulated in coupled fire-vegetation models including critical feedbacks between fire and vegetation. Such models are invaluable tools for understanding the dynamics of present and past fire regimes and for projecting changes in the future. These participating models vary from empirical models scaling functions calibrated using global satellite data to process-based models that separate fire ignition, rate of fire spread, and duration based on field and laboratory measurements.

Previous work

The FireMIP consortium provided a review on the status and the challenges of global fire modelling and defined the aims of the project (Hantson et al., 2016). A first phase of model comparison started with a documentation of participating models and the protocol for a set of simulations defined in Rabin et al. (2017). Fire modelling groups around the world contributed simulations for the historical period (1700-2013), complemented with sensitivity simulations to quantify the effect of the main drivers on fire and of fire itself on ecosystems. The systematic comparison of current approaches is achieved using a selection of benchmarking and evaluation methodologies and integration with a wide range of observational datasets.
