Land-atmosphere coupled models are widely used for investigating the land-atmosphere interaction in the studies on regional weather and hydrological analyses as well as climate projections. Land surfaces consist of many types of land cover/use and thus the exact parameterization of each type of surfaces is a key for the success of those studies. Cropland occupies substantial area in certain regions, so-called breadbasket. However, in many land surface models, croplands are expressed as a small number of virtual/actual crop species and not precisely parameterized for crop growth and crop/field management. Moreover, the spatial distributions of crop/field management as well as the characteristics of cropland are highly variable depending on farmersʼ circumstance and governmental policy. This paper provides a short review and future direction on those topics towards the improvement of land-atmosphere coupled models.
