DART research is broadly categorized along three avenues: one is the research toward data assimilation algorithmic and computational efficiency, another is toward implementing and exploiting the information in observations with one model or another, and another is to learn more about the behavior of an individual model - perhaps by looking at systematic features of the increments. CAM‐chem borrows heavily from MOZART‐4. Planetary Boundary Layer. CAM … CAM is the atmospheric component of NoRESM. DART, WRF, and MARS .
