LPJ & LPJmL Versions

LPJmL version 4.0

LPJmL version 4.0 as described by Schaphoff et al. 2018a and evaluated by Schaphoff et al. 2018b is freely available under the AGPLv3 license. You are very welcome to download the code at github. Please note that there is absolutely no support for anything, including inputs, setup etc. unless additional resources can be provided to us. In that case, please get in touch to discuss details.


LPJ Version 3: with and without managed lands

Language: C. Main development period: 2005-. Citations to refer to the code: Sitch et al. 2003; Gerten et al. 2004, Bondeau et al. 2007 (LPJmL with agriculture only); Rost et al. 2008 (LPJmL with agriculture only).


LPJ_v3.1

The PIK version of LPJ prior to the "mL" implementation. It does not contain the agricultural module.

LPJmL_v3.2 and later 3.x versions

Versions of LPJmL including the agricultural modules. We do not distribute it but can provide the code upon request for evaluatory purposes only. Please note that LPJmL version 4 (most recent version) is available openly under the AGPLv3 license (see above).

LPJ Version 2: combination with GUESS

LPJ Version 2.1 and 2.2: LPJ-GUESS

Language: C++. Main development period: 2000-.

LPJ-GUESS is developed and maintained at Lund University, Sweden. Please contact collaegues there (Benjamin Smith) for possible access to the code. Note the educational version of LPJ-GUESS intended for use on intermediate to advanced university courses. Windows installer available for download from http://www.nateko.lu.se/personal/benjamin.smith/software.

LPJmL_v2.3

This is the original testbed for the development of the LPJmL agricultural model as published by Bondeau et al. (2007). We do not distribute it but can provide the code upon request for evaluatory purposes only.


LPJ Version 1: The Original

Language: Fortran-77. Main development period: 1997-2004. Citations to refer to the code: Sitch et al. (2003); Gerten et al. (2004).

LPJ_v1.1

The originally published LPJ version used in Sitch et al. (2003). We provide this version of LPJ only for evaluatory purposes. It features a frequently too low water stress on vegetation due to insufficient formulations in the water balance. For scientifc applications we recommend to use the updated version LPJ_v1.2 (2004) if not the latest version, LPJmL version 4.

LPJ_v1.2

The latest and (at least from PIK) last version of LPJ in Fortran, including the updated hydrology of Gerten et al. (2004). We provide this version of LPJ only for evaluatory purposes. For scientifc applications we recommend to use the latest version, LPJmL version 4.
