The NPP scholar will perform climate studies through analyzing observations from the state-of-the-art satellite and reanalysis datasets (e.g., AIRS, CERES, GPM, ERA5, and MERRA-2) as well as climate model simulations from the latest phases of the Coupled Model Intercomparison Project (e.g., CMIP6). The scholar can pursue a wide range of research topics depending on his/her research interests. However, several possible research topics are listed below. How well do CMIP6 models simulate the historical climate in comparison to observations? Has the double-ITCZ bias been reduced in CMIP6 models in comparison to CMIP3 or CMIP5 models? Why does the double-ITCZ bias persist in CMIP models and how to reduce or remove it from the models? Why is there a spread of model climate sensitivity in CMIP6 models and how to constrain the model climate sensitivity using observations? How does the double-ITCZ bias influence model cloud feedback and climate sensitivity?
