Radiocarbon modeling indicates wintertime respiration of older carbon from wet meadow control points on solifluction lobes. Model results from the a dry meadow, b wet meadow (summer), and c wet meadow (winter) scenarios show a lower decay rate of light fraction carbon (kLf) and a higher decay rate of heavy plus occluded light fraction carbon (kHf*) at the wet meadow site during winter. The input partitioning parameter (α) describes the fraction of the light carbon pool that is transferred to the heavy carbon pool at each time step. d Seasonal comparison of modeled versus measured Lf and Hf* carbon fractions suggests non-steady-state carbon cycling at the wet meadow site, i.e., seasonal pools are not well captured
