Abstract

Carbon-cycle modelling is essential for testing the main carbon sources and sinks as climate forcings, and we introduce and describe GEOCARB_NET, a graphical user interface for the geologic carbon and sulfur cycle model GEOCARBSULFvolc. The software system is menu-driven, user-friendly, and the user is never far removed from the basic input parameters from which atmospheric CO₂ and O₂ concentrations can be derived. GEOCARB_NET is supplied with several published models and the user can easily test and refine these models with different parametrizations. GEOCARB_NET also contains libraries of models and proxy data, which easily can be compared with each other. Our examples focus on how to use GEOCARB_NET in the context of Phanerozoic climate change and highlights how certain key input parameters can seriously affect reconstructed CO₂ levels.

方便用户的碳循环模型和新生代气候变化的各个方面

碳循环建模对于测试作为气候作用力的主要碳源和碳汇至关重要，我们介绍并描述了 GEOCARB_NET，它是地质碳硫循环模型 GEOCARBSULFvolc 的图形用户界面。该软件系统由菜单驱动，用户界面友好，用户可以随时查阅基本输入参数，并从中推导出大气中二氧化碳和氧气的浓度。GEOCARB_NET 提供了多个已发布的模型，用户可以使用不同的参数轻松测试和完善这些模型。GEOCARB_NET 还包含模型库和替代数据，可以很容易地相互比较。我们的示例重点介绍了如何在新生代气候变化的背景下使用 GEOCARB_NET，并强调了某些关键输入参数会如何严重影响重建的二氧化碳水平。
