Description
Summary:Here, the production, transport and atmospheric release of dissolved organic carbon (DOC) from high-latitude permafrost soils into inland waters and the ocean is explicitly represented for the first time in the land surface component (ORCHIDEE) of a CMIP6 global climate model (IPSL). The model presented here mechanistically represents vegetation and soil physical processes for (a) high latitude snow, ice and soil phenomena, and (b) DOC production and lateral transport and atmospheric evasion as CO2 through soils and the river network, respectively, at 0.5° to 2° resolution. The model is subjected to a range of input forcing data, parameter testing and inclusion of contentious feedback phenomena (e.g. priming). We present simulation results for the Lena river basin over years 1901-2007, and show that our modeling approach is able to broadly reproduce observed state variables and their emergent properties across a range of interacting bio-rhizo-hydro-cryo –sphere processes, including: 1) NPP, respiration and ... : This version of ORCHIDEE has been used in ORCHIDEE MICT-LEAK, a global model for the production, transport and transformation of DOC from Arctic permafrost regions by Simon Bowring, Ronny Lauerwald, Bertrand Guenet, Dan Zhu, Matthieu Guimberteau, Ardalan Tootchi, Agnés Ducharne and Philippe Ciais ...
