1. Jack Dongarra (2021 Turing Award)

  • Credit line: “Jack Dongarra, 2022. Photo: ICLTSG / Wikimedia Commons, CC BY-SA 4.0.”
  • Dimensions: 1024x1280 px, 261 KB JPEG
  • Use context: Dongarra — University of Tennessee & ORNL — received the 2021 ACM A.M. Turing Award for LAPACK, BLAS, ScaLAPACK, MPI, and decades of numerical-library work that underpins modern computational science. A clear, well-lit portrait in front of a whiteboard full of linear-algebra notation.

2. Syukuro Manabe (2021 Nobel Prize in Physics)

  • File: assets/images/Syukuro_Manabe.jpg
  • Source URL: https://commons.wikimedia.org/wiki/File:Syukuro_Manabe_20211103.jpg
  • Direct URL: https://upload.wikimedia.org/wikipedia/commons/9/9f/Syukuro_Manabe_20211103.jpg
  • License: CC BY 4.0
  • Author: 大臣官房人事課 (Minister’s Secretariat Personnel Division, Government of Japan / MEXT)
  • Credit line: “Syukuro Manabe, 2021. Photo: Government of Japan (MEXT) / Wikimedia Commons, CC BY 4.0.”
  • Dimensions: 416x555 px, 60 KB JPEG
  • Use context: Formal portrait taken in November 2021 in connection with Manabe receiving Japan’s Order of Culture, shortly after the Nobel Prize in Physics announcement (5 October 2021) for “the physical modelling of Earth’s climate, quantifying variability and reliably predicting global warming.” Note: an older Manabe_portrait.jpg already exists in the repo (236x296, used in Part 2); this new file is the higher-quality 2021-era version for the Nobel discussion in Part 3.

3. Modern HPC machine (CSCS Alps supercomputer)

  • File: assets/images/CSCS_Alps_supercomputer.jpg
  • Source URL: https://commons.wikimedia.org/wiki/File:CSCS_Supercomputer_Alps_1.jpg
  • Direct URL: https://upload.wikimedia.org/wikipedia/commons/9/9c/CSCS_Supercomputer_Alps_1.jpg
  • License: CC BY-SA 3.0 Unported
  • Author: Marco Abram, Swiss National Supercomputing Centre (CSCS)
  • Credit line: “The Alps supercomputer (HPE Cray EX) at CSCS, Lugano. Photo: Marco Abram / CSCS, CC BY-SA 3.0.”
  • Dimensions: 1200x800 px, 278 KB JPEG
  • Use context: Filename slot was originally ECMWF_supercomputer.jpg, but ECMWF’s own photos on Flickr are CC BY-NC-ND 2.0 (incompatible with this blog’s PD/CC-BY/CC-BY-SA standard), and no suitable ECMWF image exists under a compatible license on Wikimedia Commons. Swapped in the CSCS Alps image as an equivalent “modern European HPC machine used for weather and climate” — CSCS hosts MeteoSwiss’s operational NWP runs and couples to ECMWF output, so the thematic fit is strong. The photo is also striking (the “ALPS” machine-room wall branding reads clearly). Body text should describe it accurately (“CSCS Alps, not ECMWF”).

4. GFS forecast chart

  • File: assets/images/GFS_forecast.png
  • Source URL: https://commons.wikimedia.org/wiki/File:GFS_850_MB.PNG
  • Direct URL: https://upload.wikimedia.org/wikipedia/commons/d/d9/GFS_850_MB.PNG
  • License: Public domain (US Government work, 17 U.S.C. § 105)
  • Author: NWS / NCEP / NOAA
  • Credit line: “96-hour GFS forecast of 850 hPa height, temperature and wind, 21 July 2006. NOAA / National Weather Service, public domain.”
  • Dimensions: 1280x1024 px, 135 KB PNG
  • Use context: Classic monochrome NCEP forecast chart style — upper-air contours, wind barbs, frontal analysis. Perfect illustration of operational NWP output from the Fortran-heavy GFS model. Caveat for body text: it’s 850 hPa, not 500 hPa, but the visual is identical in character; label accurately.

5. Modern Fortran code screenshot

  • File: assets/images/Modern_Fortran_code.png
  • Source URL: https://commons.wikimedia.org/wiki/File:Fortran90_Programm_auf_Deutsch.png
  • Direct URL: https://upload.wikimedia.org/wikipedia/commons/e/ee/Fortran90_Programm_auf_Deutsch.png
  • License: CC0 1.0 Universal (Public Domain Dedication)
  • Author: Rhetos (Wikimedia Commons user)
  • Credit line: “Fortran 90 program (quadratic formula). Source: Rhetos, CC0 / public domain.”
  • Dimensions: 650x658 px, 80 KB PNG
  • Use context: A PROGRAM abcformel with IMPLICIT NONE, type declarations (REAL :: a, b, c), the :: syntax introduced in F90 — a clean, honest example of modern Fortran style. Comments in German, which is fine (the visual of IMPLICIT NONE and :: is the point). Editor is Gedit/similar.

6. Fortran logo (modern Fortran community)

  • File: assets/images/Fortran_logo.svg
  • Source URL: https://commons.wikimedia.org/wiki/File:Fortran_logo.svg
  • Direct URL: https://upload.wikimedia.org/wikipedia/commons/b/b8/Fortran_logo.svg
  • License: Public domain (below threshold of originality; simple geometric shapes)
  • Author: Fortran-lang community (uploaded by HapHaxion, 2020)
  • Credit line: “Fortran logo. Source: fortran-lang.org, public domain.”
  • Dimensions: SVG (scalable), 1.1 KB
  • Use context: Official logo of the modern Fortran community (fortran-lang.org, fpm, stdlib, LFortran). Pairs well with any discussion of the Fortran renaissance circa 2020-2026.

7. NASA global temperature anomaly (2024)

  • File: assets/images/NASA_temperature_anomaly.png
  • Source URL: https://svs.gsfc.nasa.gov/5450/
  • Direct URL: https://svs.gsfc.nasa.gov/vis/a000000/a005400/a005450/2024GISTEMPMap.png
  • License: Public domain (NASA, US government work)
  • Author: NASA Scientific Visualization Studio / NASA GISS (GISTEMP)
  • Credit line: “Global surface temperature anomaly, 2024 (GISTEMP baseline 1951-1980). NASA Scientific Visualization Studio, public domain.”
  • Dimensions: 3840x2160 px (4K), 3.4 MB PNG
  • Use context: The 2024 frame from NASA’s long-running GISTEMP visualisation series — a stark red Earth with a year counter reading “2024”. Thematically perfect for the Part 3 discussion of climate modelling outputs and the Nobel (Manabe 2021). Full resolution saved; also used as source for the header below.

8. Header image — “Fortran’s Afterlife”

  • File: assets/images/header-fortran-afterlife.jpg
  • Source: Resized from NASA_temperature_anomaly.png (3840x2160 -> 1600x900, Lanczos, JPEG q88)
  • License: Public domain (derivative of NASA SVS public-domain source)
  • Credit line: “Header derived from NASA Scientific Visualization Studio, 2024 GISTEMP global temperature anomaly, public domain.”
  • Dimensions: 1600x900 px, 172 KB JPEG (16:9)
  • Use context: Dramatic global climate image in the same visual family as header-climate.jpg, header-model-clouds.jpg, header-butterfly.jpg. A model output, not a photo of a machine — which fits Part 3’s theme (Fortran’s afterlife is defined by the scientific outputs it still produces, not the hardware).

Notes and skips

  • ECMWF official photos: Skipped. ECMWF Flickr (flickr.com/photos/ecmwf/) is CC BY-NC-ND 2.0; incompatible with the PD/CC-BY/CC-BY-SA policy established in earlier posts. ECMWF’s media-centre page has no clearly-licensed PD alternative. Used CSCS Alps as a thematically-equivalent modern European HPC machine.
  • NCAR CESM visualization gallery: Skipped. UCAR’s terms require case-by-case clearance for non-news-media/non-nonprofit reuse; the gallery images are not blanket-CC-licensed. NASA SVS temperature-anomaly map covers the same thematic slot (climate-model output) with unambiguous public-domain status. If a specific CESM visualisation is needed, email copyright@ucar.edu for clearance.
  • LAPACK / BLAS visual: Skipped. No clean CC/PD option surfaced. The netlib homepage and the LAPACK logo exist but lack clear licensing. The Dongarra portrait plus narrative text is sufficient to carry the LAPACK/BLAS thread.
  • NCAR-Wyoming Cheyenne / Derecho: Not on Wikimedia Commons under a clean license. Skipped.
  • Existing assets still usable for Part 3: Manabe_portrait.jpg (Part 2 version; the new Syukuro_Manabe.jpg above is for the Nobel section), NCAR_Mesa_Lab.jpg, GFDL_building.jpg, Smagorinsky_portrait.jpg, header-climate.jpg, header-model-clouds.jpg.
