CESM Tutorial 2022

The 2022 CESM Tutorial will take place 08 - 12 August 2022. At this time we are planning to have the 2022 Tutorial in-person, however we are aware there is continued uncertainty associated with the COVID-19 pandemic. Specific details regarding the Tutorial content and format will be posted to the website listed below as soon as they are available. In the case that we are unable to hold the Tutorial in-person we will return to online only format with activities occurring during a 9 am to 3 pm MDT window including live lectures and practical sessions.

The CESM Tutorial will consist of:

• A mix of live and pre-recorded lectures on simulating the climate system. Students are expected to watch the pre-recorded lectures before the corresponding live Q&A session;
• Pre-recorded practical sessions on how to run CESM, modify components, and analyze the output. During the tutorial week there will be daily live office hours dedicated to help students with any potential problems encountered during the practical sessions. Again, students are expected to complete the practical sessions before the corresponding office hours;

The CESM Tutorial is targeted at the graduate student level (2nd year and beyond), but postdocs, research scientists, and faculty members are also welcome to apply. We are committed to providing equal opportunity for all applicants regardless of race, age, creed, color, religion, national origin or ancestry, sex, gender, disability, veteran status, genetic information, sexual orientation, gender identity or expression, or pregnancy.

Acceptance criteria

• Balance attendees across institutions
• Project descriptions that fit with broader CESM goals and activities
• Preference given to early career graduate students, though we will aim for a mix of graduate students, postdocs, early career research scientists, and faculty.

We very much encourage applications from students from diverse backgrounds of all kinds; whatever your gender, race/ethnicity, gender identity, gender expression, sexual orientation, body size and shape, veteran status, and/or disability, you are very welcome here at NCAR.

Introduction to Programming & Fortran Lesson

Lesson Description:

This 2-unit module from The COMET Program introduces users to scientific programming structures and methods and the history, basic syntax and functionality of Fortran, which makes up much of CESM.



Recommendations for Module Use:

• Users who have little to no programming experience should take both units in full
• Users that do have some programming experience, such as a web-based language like HTML, but have limited experience in scientific programming, such as a C-based languages, should start with unit 1 and may find they can complete it quickly. While unit 2, covering Fortran and CESM Fortran examples, should be taken in full
• Users that have significant scientific programming experience (C-based languages, for example) can safely start in unit 2, which covers Fortran and CESM Fortran examples
• Users that have significant programming experience in Fortran can likely begin at the "Fortran and CESM" subsection (near bottom of table of contents) in unit 2

Currently, my research focuses mainly on atmospheric circulations in Southern Oceans and its impact on various Sea-ice parameters. I am using climate models to study how well they simulate sea-ice in the Antarctic and for understanding the impact of extreme weather on southern oceanic sea-ice in the future. I have previously worked as a researcher in a climate modeling institute in India where the focus of my work was on understanding the impact of changing Antarctic sea-ice on South-Asian Monsoons. In my free time, I like to cook, learn and try out various new and different recipes. If not in my kitchen, you will find me outside in the natural world, travelling whenever I get time.

Vidya Venkatesan

I am an Astrophysics Ph.D. student at the University of California, Irvine. I work with Professor Aomawa L. Shields and explore the climate and habitability of exoplanets by combining observational data with computer models. Most habitable zone studies assume a circular orbit, but ~50% of confirmed planets have eccentricity greater than 0.1. As these planets spend a significant amount of time at large distances from their host star, they may have conditions where the atmosphere falls onto the surface and forms a variety of frozen species like carbon dioxide ice and water ice. My current NASA FINESST-funded project explores how the interaction between host star spectrum and surface ice composition shapes the fraction of an eccentric planet’s year over which it can be habitable using a suite of climate models. Besides research, I am also involved in outreach with the Rising Stargirls program and collaborate on some DEI efforts with the Cal-Bridge program. My hobbies include reading/watching science fiction, running, traveling, and one of my life goals is to become a certified scuba diver!

Laura Sobral Verona

I am a second-year PhD student in Physical Oceanography at the Oceanographic Institute of the University of São Paulo (Brazil). I am studying the responses of the Atlantic ocean-atmosphere system to volcanic forcing. Specifically, my focus is to identify how large eruptions can change the dominant mechanisms of interdecadal variability of the Atlantic subtropical subsurface circulation, how it is connected with the Tropical Atlantic variability, and, therefore, understand how the South American hydroclimate responds to these processes. For that, I use an ensemble of climate models simulations for the Last Millennium and experiments based on large volcanic eruptions such as Tambora. In my free time, I love outside sports like cycling, outrigger canoeing, and hiking. My other hobbies include aerial silk, studying french, and baking."

Peidong Wang
