Next week, #NASA Goddard Institute for Space Studies turns 60, and we are celebrating our anniversary with some retrospective talks on our history… and forward thinking talks about our future.

I have been appointed to present “History and Future of #Climate Modeling”, so I’ve been interviewing many GISS alumni.

The back-stories to the published development are fascinating.

I’ve asked my boss to get a film maker to document these oral histories better. It would make a great documentary imho.

Instantaneous cloud cover from Somerville et al 1975. This early NASA GISS weather model (derivative of UCLA’s Mintz and Arakawa 3-layer model) was moved wholesale to GSFC in the late 1970’s and evolved into their weather model, while NASA GISS started from scratch with a 1D Radiation model.
The first publication of what became the GISS climate model. At this point, it is mostly a 1D radiative model driven by Hansen and Lacis. “Climate Impact of Increasing Atmospheric Carbon Dioxide” Hansen et al 1981. Jim was inspired by seminal work of Suki Manabe at GFDL, but he believed (turns out rightly) that the global radiative balance is THE critical thing to get global temperature…
