| Zusammenfassung |
| We present version 14 of the photolysis module JVAL. Taking
atmospheric conditions as input, JVAL calculates photolysis rate
coefficients, i.e. the speed of dissociation of atmospheric
molecules in the sunlight. Computational efficiency is obtained
through the use of parameters for polynomial curve fitting and lookup
tables. Physical changes compared to the previous version include a
parameterization of the Lyman-alpha absorption, and an update of the
UV/VIS cross sections to the most recent recommended values. JVAL also
includes the auxiliary program JVPP (JVal PreProcessor) which
pre-calculates these parameters based on the absorption cross sections
and quantum yields of the atmospheric molecules. It is possible to
use JVAL either as a stand-alone program or as a module inside the
Modular Earth Submodel System (MESSy). JVAL is a community model
published under the GNU General Public License. |
