Data and code

A complete and up-to-date overview of our open source products is on github here.

As a group, we are committed to an Open Science Practice. We’re building an environment of open source tools for ecosystem data and modelling. This should empower the community to use latest methodological innovations, developed in our group. Here is a list of our most important contributions:

Code

rpmodel

An implementation of the P-model for leaf-level acclimation of photosynthesis Stocker et al., 2019 GMD). Implemented as an R package (fully in R). This is used as reference code for P-model implementations in other modelling frameworks and for experimental model development. For efficient time series simulations use its implementation within rsofun.

Code on CRAN

Development code

rsofun

A modelling framework for site-scale simulations of ecosystem processes, implemented as an R package (back-end in Fortran 90). Implements the following models:

  • P-model for leaf-level acclimation of photosynthesis, Stocker et al., 2019 GMD
  • SPLASH for bioclimatic variables, including the surface radiation budget and the soil water balance, Davis et al., 2017 GMD
  • LM3-PPA for comprehensive simulations of ecosystem carbon and water cycling, tree growth, and tree cohort-explicit forest dynamics following the Perfect Plasticity Approximation, Weng et al., 2015

Development code

ingestr

Functions to extract (ingest) environmental point data from large global files or remote data servers and create time series at user-specified temporal resolution. Facilitates forcing and evaluation data preparation for rsofun. The main functionalities are:

  • Temporal downscaling from montly to daily resolution
  • Quality filtering, temporal interpolation and smoothing of remote sensing data
  • Handling of different APIs and file formats, returning ingested data in tidy format.

DYPTOP

A cost-efficient TOPMODEL implementation to simulate sub-grid spatio-temporal dynamics of global wetlands and peatlands (Stocker et al., 2014 GMD). Written in Fortran.
