FOCUS PEARL 3.3.3 is a bug-fix release. The following errors were fixed:
 | In version 2.2.2 a small bug was found in the simulation of the soil temperatures. This bug has been solved in version 3.3.3. |
| | The database of version 2.2.2 was based on wrong dates for the maximum LAI and for leaf fall in the Porto-apples scenario. These wrong dates were 31 July and 30 September, whereas the correct dates are 30 June and 31 October. Version 3.3.3 is based on these correct dates. |
| | In version 2.2.2 occasionally a run failure occurred for substances with Freundlich exponents exceeding 1.0. The procedure for the calculation of the time step has been improved, so that this run failure does not occur anymore in version 3.3.3. |
| | In version 2.2.2 there was a bug was in the calculation of the temperature-dependency of the sorption coefficient: this bug affected only results of runs that assumed a non-zero molar enthalpy of sorption whilst zero is the default value of this enthalpy. This bug has been eliminated in version 3.3.3. |
| | The upper limit of the wash-off coefficient has been changed from 0.1 m-1 into 100 m-1 because the 0.1 m-1 was too low. |
| | Performance has improved by about 25% by using more efficient loop structures and more efficient screen handling. |
