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 most up-to-date version of LPJ from PIK. We recommend it as the version to use in your scientific studies. It does not contain the agricultural module. Please ask for correct citation, as this version is continuously being updated. We do not provide input datasets.

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_v2.3This 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_v1.1The 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, LPJ_v3.1.
LPJ_v1.2The 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, LPJ_v.3.
