Eugenia Enriqueta Kalnay
1942–2024

Eugenia Kalnay, who made highly consequential theoretical and practical contributions to a wide range of scientific subjects, especially numerical weather prediction and predictability, and who was a beloved mentor to generations of students, passed away on August 13, 2024.

Eugenia’s seminal scientific contributions were marked by her exceptional creativity and singular ingenuity, often in the service of practical goals beyond the usual remit of academics. Her leadership of modeling and prediction research elevated the United States weather service to the top rank. She was the driving force behind the NCEP/NCAR Reanalysis Project, which, according to the American Academy of Arts and Sciences, “is certainly the most scientifically fertile dataset in climate science.”
