Towards an operational seasonal forecasting system for the Arabian Peninsula

Seasonal forecasting is a key tool for managing climate risks in arid regions, yet its performance over the Arabian Peninsula (AP) remains insufficiently characterized. In this study, we developed and evaluated a multi-model seasonal forecasting system for the AP, comparing simul...

Antarctic sea ice response to meltwater due to Antarctic ice sheet mass loss in a multi-model ensemble

Abstract. We present the first multi-model study of the Antarctic sea ice response to enhanced meltwater due to dynamic mass loss from the Antarctic ice sheet. This meltwater flux (and its future increase under global warming) is not included in the most recent state-of-the-art c...

Mutual constraints on global aerosol composition from novel PACE data and ModelE

Abstract. Aerosol climate impacts remain uncertain, in part because global aerosol composition observations have been unavailable to constrain Earth System Models (ESMs). We present the first comparison of aerosol composition from the Plankton, Aerosol, Cloud, ocean Ecosystem (PA...

The Cold-Air Outbreaks in the Marine Boundary Layer Experiment model-observation intercomparison project (COMBLE-MIP) – Part 1: Model specification, observational constraints, and preliminary findings

Models struggle to represent the coupled microphysical, turbulent and radiative processes within widespread, long-lived marine cold-air outbreak (CAO) cloud fields, contributing to forecast and climate biases. Here we combine ground-based and satellite measurements to initialize...

The Cloud Feedback Model Intercomparison Project (CFMIP) contribution to CMIP7

Cloud processes constitute one of the key uncertainties for climate change projections. The fourth iteration of the Cloud Feedback Model Intercomparison Project, CFMIP4, contributes to the Coupled Model Intercomparison Project phase 7 (CMIP7), by providing a set of global climate...

Efficient nitrogen management as a win-win strategy for air quality, health, and climate

Reactive nitrogen (Nr) management links climate policy, air quality and food production, yet its combined impacts remain poorly quantified. Here, we conduct ensemble simulations with two global climate models, Goddard Institute for Space Studies (GISS) and Community Earth System...
