Fifty undergraduate students (10 per year for five years) will be recruited to participate in a 10-week summer residential research experience in Atmospheric Science Department at Colorado State University. The vision is that graduate students in Earth System Science will reflect the diversity of life experiences and demographic characteristics of the US population. The intended impact of this REU-site is to recruit a talented and diverse pool of undergraduate students into graduate study in Earth System Science through the following objectives: (1) to provide a diverse cohort of undergraduate students the opportunity for discovery-based exploration of Earth System Science; (2) to give interns a feel of the graduate school experience; (3) to provide training in effective communication for cross-disciplinary studies, including those that apply data science methods to the Earth Sciences; and (4) to introduce students to the concept of implicit bias, its effects, and counter-measures to promote a more vibrant and productive scientific community.
