FOCUS PEARL and GeoPEARL use the Interbase Database Management System, which is installed as part of the (Geo)PEARL installation. Users can use Interbase free during the first 90 days, but they have to ask for a so-called deployment licence thereafter. The registration fee will be covered by the PEARL team, so registration is free of charge for the user. To get a free deployment license, you have to register as a (Geo)PEARL user.
Download the most recent version of FOCUS PEARL from the FOCUS PEARL website. Following recommendations of the FOCUS working group on version control, this is the only place where you can download the model. The current FOCUS PEARL version is FOCUS PEARL version 3.3.3.
Download the GeoPEARL model from the PEARL website. Following recommendations of the GeoPEARL working group on version control, this is the only place where you can download the model. This version should be used when submitting a registration dossier.

Download the ASCII version of the GeoPEARL model from the PEARL website. Following recommendations of the GeoPEARL working group on version control, this is the only place where you can download the model. As described in the manual, there are two versions available, i.e. a version with a graphical user interface and an ASCII version. The ASCII version should only be used by experienced users; it can be used for grid computing. Please refer to the manual for further details. You can also download the map with the unique combinations (or plots) here.
FOCUS PEARL 2.2.2 uses Interbase as a database system instead of Microsoft Access 97. Advantage is that the system is no longer dependent on specific Office versions. However, old databases must be transferred via a separate software tool, i.e. "PEARL 1 to 2 Converter". This tool can be downloaded here.

In the PEARL context, a compound residing in the non-equilibrium domain is not subject to transformation, which implies that the half-life of transformation refers to the equilibrium domain only. An important consequence is that the transformation half-life, which usually refers to the total mass content, should be obtained in a special procedure. The PEARLNEQ program can be used to obtain the half-life at reference temperature, the desorption rate coefficient, and the non-equilibrium sorption coefficient in the case of sorption/desorption kinetics. If the incubation experiment has been carried out at multiple temperatures, the molar activation energy can be optimized simultaneously.
