SURF interns contribute to CliMA Science at Caltech Over a 10-week summer period, the CliMA project welcomed three Summer Undergraduate Research Fellowship (SURF) interns. These undergraduate students were mentored by CliMA project scientists and software engineers on individual research projects that contributed to our model development. Thanhthanh Noel Nguyen, a second-year Caltech undergraduate, collaborated with Software Engineer Julia Sloan and the Land team. Her project focused on calibrating land models using FLUXNET observations, investigating how vegetation parameters vary with environmental conditions.

Rethinking Vegetation Optics in Climate Models By Renato Braghiere Vegetation plays a critical role in regulating Earth’s climate by absorbing sunlight, exchanging moisture with the atmosphere, and sequestering carbon. Yet, how vegetation is represented in climate models has remained surprisingly static for decades. Most climate models use a simplified classification called plant functional types (PFTs) — broad categories like “tropical trees” or “grasses” — and assign homogeneous optical properties to each.

Constraining 21st century ocean circulation changes The ocean contains a system of currents that connects different ocean basins. A significant feature of this system is found in the Atlantic Ocean basin and often referred to as the Atlantic meridional overturning circulation (AMOC). The AMOC is crucial because it transports warm water northward and helps circulate water between the deep ocean and the surface. As a result, the AMOC plays a vital role in regulating both regional and global climates and can influence weather patterns, such as the African and Indian monsoons, and the summer climate in North America and Western Europe.

A simple diagram showing the relationship between component models and the coupler, which exchanges information between them. Component models can easily be added, removed, or replaced with ClimaCoupler’s modular structure.

🌍 CliMA is developing an #ESM with independent atmosphere, ocean, and land components. Each can be run alone for focused studies or together for global climate predictions. ClimaCoupler.jl links these models, facilitating data exchange and comprehensive analysis. Read blog about it: bit.ly/3W7FWiD

Chart with vertical-shift and amplitude axis. Plots the resulting ensemble from a calibration in relation to a starred point labled "truth".

We're thrilled to introduce a powerful new package that brings the “Calibrate, Emulate, Sample” (CES) workflow to Julia, accelerating Bayesian inversion and uncertainty quantification.
