Ants Leetmaa Memorial Symposium:
Climate Variations, Change, and Predictability

Ants Leetmaa

Wednesday, June 20, 2018

Venue: Princeton University Frick Lab (Main Campus)

Please join NOAA’s Geophysical Fluid Dynamics Laboratory (GFDL) and Princeton University’s Atmospheric and Oceanic Sciences program as we honor the life ​and career of a departed colleague, Dr. Ants Leetmaa, former director of GFDL. Dr. Leetmaa served as GFDL director (2001–2007), and director of NOAA’s National Weather Service Climate Prediction Center (1997–2001). His contributions to climate variability and predictability research and forecast applications substantially advanced how we understand and predict natural climate variability, and the role of oceans in the climate system.
