GSWP3 is an ongoing terrestrial modeling activity that produces a long-term land reanalysis and investigates the changes of the energy-water-carbon cycles through the 20th and 21st century. A wide range of state-of-the-art land surface, hydrologic, and ecological models make up super-ensemble land simulations combining big data, and are evaluated by process-wise model verifications and uncertainty estimations. GSWP3 also plays a role as a liaison, sharing experiment designs and input datasets as a standard for the broader modeling community.
In ALMIP2, land surface, vegetation, and hydrological models will be evaluated and inter-compared in order to identify key processes that are not well-modeled over West Africa, and to offer guidelines for future model development for all three classes of models. Phase two deals with local to meso scales.

PALS PLUMBER is a model comparison experiment that uses out-of-sample empirical models as benchmarks.

The LoCo project’s goal is to understand, model, and predict the role of local land-atmosphere coupling in the evolution of land-atmosphere fluxes and state variables, including clouds.

The Coupling Metrics Toolkit (CoMeT) brings together many commonly used land-atmosphere coupling metrics into a single, standardized set of Fortran 90 modules. Calculate everything from soil moisture retention over time, to the link between convective initiation and surface properties.
The LS3MIP experiment intends to assess the performance of current land surface modules of Earth System Models and quantify land surface feedbacks in a changing climate. Its goal is to provide a comprehensive assessment of land surface-, snow-, and soil moisture-climate feedbacks, and to diagnose systematic biases in the land modules of current ESMs using constrained land-module only experiments.
The GEWEX SoilWat Initiative brings together two research communities to improve the representation of soil and subsurface processes in climate models. The soil and groundwater community and the climate modeling community (the latter represented by GEWEX) are working together to identify the most pressing challenges and topics related to this effort.
