Hydrological modelling on atmospheric grids: using graphs of sub-grid elements to transport energy and water Open
Land surface models (LSMs) use the atmospheric grid as their basic spatial decomposition because their main objective is to provide the lower boundary conditions to the atmosphere. Lateral water flows at the surface on the other hand requi…
Evaluation of Native Earth System Model Output with ESMValTool Open
Projections from Earth system models (ESMs) are essential to allow for targeted mitigation and adaptation strategies for climate change. ESMs are state-of-the-art numerical climate models used to simulate the vastly complex Earth system in…
Evaluation of native Earth system model output with ESMValTool v2.6.0 Open
Earth system models (ESMs) are state-of-the-art climate models that allow numerical simulations of the past, present-day, and future climate. To extend our understanding of the Earth system and improve climate change projections, the compl…

The Climatic Impact‐Driver Framework for Assessment of Risk‐Relevant Climate Information Open
The climate science and applications communities need a broad and demand‐driven concept to assess physical climate conditions that are relevant for impacts on human and natural systems. Here, we augment the description of the “climatic imp…

Increased risk of near term global warming due to a recent AMOC weakening Open
Some of the new generation CMIP6 models are characterised by a strong temperature increase in response to increasing greenhouse gases concentration 1 . At first glance, these models seem less consistent with the temperature warming observe…
Increased risk of near term global warming due to a recent AMOC weakening Open
This archive contains data from the IPSL-CM6A-LR ensemble of extended historical simulations dataset used in the main Figure of the publication: Bonnet et al., 2021, Nature Communication, "Increased risk of near term global warming due to …

Presentation and Evaluation of the IPSL‐CM6A‐LR Ensemble of Extended Historical Simulations Open
The Institut Pierre‐Simon Laplace Climate Modeling Center has produced an ensemble of extended historical simulations using the IPSL‐CM6A‐LR climate model. This ensemble (referred to as IPSL‐EHS) is composed of 32 members over the 1850–205…
Better representation of dust can improve climate models with too weak an African monsoon Open
The amount of short wave radiation absorbed by dust has remained uncertain. We have developed a more accurate representation of dust absorption that is based on the observed dust mineralogical composition and accounts for very large partic…

The Tuning Strategy of IPSL‐CM6A‐LR Open
The assessment of current and future risks for natural and human systems associated with climate change largely relies on numerical simulations performed with state‐of‐the‐art climate models. Various steps are involved in the development o…
Model evaluation expectations of European ESM communities: results from a survey Open
Developing an Earth system model evaluation tool for a broad user community is a real challenge, as the potential users do not necessarily have the same needs or expectations. While many evaluation tasks across user communities include com…
Dust Induced Atmospheric Absorption Improves TropicalPrecipitations In Climate Models Open

Improved Near‐Surface Continental Climate in IPSL‐CM6A‐LR by Combined Evolutions of Atmospheric and Land Surface Physics Open
This work is motivated by the identification of the land‐atmosphere interactions as one of the key sources of uncertainty in climate change simulations. It documents new developments in related processes, namely, boundary layer/convection/…
