Smagorinsky biographical — ALL VERIFIED

Joseph Smagorinsky born 29 January 1924 in New York City. (Wikipedia, Encyclopedia.com, Franklin Institute)
Died 21 September 2005, aged 81, Hillsborough, NJ, after Parkinson’s. (Princeton News obituary, patch.com)
Parents from Gomel, Belarus — fled pogroms. (Wikipedia: “His parents were from Gomel, Belarus, which they fled during the life-threatening pogroms.”)
Studied at Brown then MIT during army service. Instructor at MIT was Ed Lorenz. (Wikipedia)
NYU: BS 1947, MS 1948, PhD 1953 under Bernhard Haurwitz. (Wikipedia, Encyclopedia.com)
Wife Margaret (née Knoepfel) — first woman statistician hired by Weather Bureau, ENIAC team member. (Wikipedia, Margaret Smagorinsky obituary in Princeton Patch)
Director of GFDL 1955-1983 (~28 years, retired January 1983). (Wikipedia)

Founded 1955 as General Circulation Research Section of US Weather Bureau, at von Neumann’s instigation, under Smagorinsky.
Founding location: Suitland, Maryland, near JNWP unit. (Sloan/U Michigan center_descriptions/i.GFDL.html: “initially located in Suitland, Maryland (near the Weather Bureau’s JNWP unit), later moved to Washington, D.C.”)
Renamed General Circulation Research Laboratory 1959.
Renamed Geophysical Fluid Dynamics Laboratory (GFDL) 1963.
Moved to Princeton’s Forrestal Campus 1968.
NOT VERIFIED: specific date “23 October 1955” — only year is confirmed. Post does not mention a specific date in 1955, only the year. No issue.

Syukuro Manabe born 21 September 1931, Ehime Prefecture, Japan.
Birthplace name: Wikipedia, Japan Policy Forum, and post all use “Shinritsu Village” (now part of Shikokuchuo City). The official Nobel Prize biographical uses “Shingu Village” — likely the same place under a different romanization or post-merger naming. Post’s “Shinritsu Village, Ehime Prefecture” is acceptable.
University of Tokyo: BA 1953, MA 1955, DSc 1958 (consensus from Wikipedia, Britannica, Grokipedia, Japan Policy Forum). Nobel Prize biographical says DSc 1959, but this is the outlier. Post’s 1958 is consistent with consensus.
Arrived USA 1958, formally joined General Circulation Research Section 1959 (per Sloan/U Michigan, confirmed). Post is correct: “arrived in Washington, D.C. in 1958 and formally joined the General Circulation Research Section in 1959.”
Worked at GFDL/Weather Bureau lineage until 1997. (Nobel Prize, Wikipedia)
Returned to Japan 1997-2001, Frontier Research System for Global Change, directed Global Warming Research Division. (Nobel Prize, Wikipedia)
Returned to Princeton 2002. (Nobel Prize, Wikipedia)
Father and grandfather were physicians running village clinic. (Japan Policy Forum, Nobel biographical)
Was 90 years old at Nobel announcement. Born Sep 1931, awarded Oct 2021. (Verified)

Date announced: 5 October 2021. (Princeton News)
Citation: “for the physical modelling of Earth’s climate, quantifying variability and reliably predicting global warming.” (Nobel Prize official)
Recipients: Manabe and Hasselmann shared 1/2 of prize (each 1/4), Parisi received the other 1/2. Post’s framing “one half … to Manabe and Hasselmann, the other half … to Parisi” is correct.
Quote: “I did these experiments out of pure scientific curiosity. I never realized that it would become a problem of such wide-ranging concern for all of human society.” — verified via Princeton News.

Manabe & Wetherald (1967), “Thermal Equilibrium of the Atmosphere with a Given Distribution of Relative Humidity,” J. Atmos. Sci. 24(3), 241-259. (Wikipedia, ADS, Carbon Brief)
- Voted most influential climate paper in Carbon Brief survey (8 nominations). VERIFIED.
- CO2 doubling result 2.36°C (300→600 ppm, from Table 5). Post correctly quotes 2.36°C. VERIFIED via climategraphs analysis.
Manabe & Bryan (1969), “Climate Calculations with a Combined Ocean-Atmosphere Model,” J. Atmos. Sci. 26(4), 786-789. First coupled ocean-atmosphere GCM. VERIFIED via AMS, IEEE ETHW PDF, NOAA.
Manabe & Wetherald (1975), “The Effects of Doubling the CO2 Concentration on the Climate of a General Circulation Model,” J. Atmos. Sci. 32(1), 3-15. ~3°C average warming, with Arctic amplification due to snow/ice retreat. VERIFIED via AMS abstract listing.
Smagorinsky (1963), “General Circulation Experiments with the Primitive Equations: I. The Basic Experiment,” Mon. Wea. Rev. 91(3), 99-164. 9-level hemispheric primitive-equation GCM on IBM 7030 Stretch. NOT DIRECTLY VERIFIED in this session (AMS returned 403); but post’s description matches widely-known facts.

Born 1936, died 9 October 2011, Trenton, NJ, age 75. (Legacy.com obituary, Wikidata, Mather-Hodge)
Worked at GFDL with Manabe for decades. Co-authored 1967 and 1975 CO2 papers.

1979 NAS Ad Hoc Study Group on Carbon Dioxide and Climate, chaired by Jule Charney.
ECS estimate ~3°C ± 1.5°C (range 1.5-4.5°C).
Post correctly states “3 degrees C (plus or minus 1.5 degrees C)”.

Published participants: Charney, Fjortoft, von Neumann; co-workers Smagorinsky, Platzman, Freeman; Margaret Smagorinsky and others as computer operators.
Post correctly lists Charney, Fjortoft, Freeman, Platzman, Smagorinsky.

9-level hemispheric primitive-equation GCM, IBM Stretch (7030). Stretch was world’s fastest 1961-1964. (Standard fact.)
Introduced Smagorinsky subgrid-scale turbulence closure model. (Standard fact.)
Subsequent extension by Lilly and Deardorff into Smagorinsky-Lilly LES model — standard.
