Internal and structural variability in global urban climate projections in CMIP6
… that are specific to built landscapes. A robust modeling framework to address uncertainty in local- or regional-scale climate change should include the roles of internal variability, model parametric and structural uncertainty, and scenario uncertainty. Quantitative attributions of the structure …

Investigating Tropospheric Hydrogen Peroxide Trends from 1950-2014
… the history of tropospheric oxidants relies on modeling studies. We quantify the global H₂O₂ burden and trends between 1950 and 2014 from the Community Earth System Model - Whole Atmosphere Community Climate Model version 6 (CESM2-WACCM6). This is a global chemistry-climate model, with each of …

The influence of heat transport on Arctic amplification
… Arctic amplification have used either a single model run or have compared results from a multi-model ensemble. While the multi-model ensemble approach may potentially average out biases in individual models, the ensemble spread confounds the model differences and the internal climate …

Assessing and Improving the Representation of Hydrologic Processes in Atmospheric, Ocean, and Land Modeling and Dataset Generation
Water is essential to life on Earth. Since water exists in all three phases (solid, liquid, and gas) on Earth, it exists in various reservoirs throughout the planet that compose the hydrologic cycle, and its movement through these reservoirs requires energy. Thus, water is a key component of the …
