Report summary

Columbia University Lamont Doherty Earth in 2022-2026 reads as a 48-PI network with 26 internal PI collaborations. The research center of gravity is Earth and Planetary Sciences as the leading field (39% of slots across 35 PIs; 35 labels), Atmospheric Science as the leading subfield (22% of slots across 24 PIs; 24 labels), and Cryospheric studies and observations as the leading topic (7% of slots across 10 PIs; 10 labels). Overall the pattern is balanced: there is enough structure to identify active groups, while the field mix still leaves room for multiple research identities. The most prominent PIs by weighted works are Paul E. Olsen (11.2 weighted works; Geological formations and processes, Geology and Paleoclimatology Research); Daniel M. Westervelt (11.1 weighted works; Air Quality Monitoring and Forecasting, Air Quality and Health Impacts). The strongest pairings are Michael K. Tippett and Jorge L. García‐Franco (5 shared works, weight 2.3). The strongest breakdown groups are group 1 with 10 PIs, 9 internal connections, weight 9, around Global and Planetary Change, Atmospheric Science, Environmental Engineering, led by Daniel M. Westervelt, Michael K. Tippett, Jorge L. García‐Franco; group 2 with 9 PIs, 9 internal connections, weight 8.3, around Atmospheric Science, Geophysics, Earth-Surface Processes, led by Paul E. Olsen, Folarin Kolawole, William Menke.
