A fantastic opportunity for early-mid career scientists to carry out research at the forefront of weather and climate modelling, open to international candidates too! #postdoc #meteorology #climate #research

But, perhaps more importantly, we suggest that the inclusion of simple clumping factors in these 1D schemes is unlikely to capture the effect of the 3D structure on photosynthesis correctly. More on this coming out soon.

In a nutshell, the results suggest that land surface models, which tend to use 1D radiative transfer solutions for vegetation canopies, will tend to predict more photosynthesis per unit leaf area than models incorporating more realistic 3D structure.

The influence of 3D canopy structure on modelled photosynthesis Vegetation is one of the largest terrestrial sinks of atmospheric carbon dioxide, driven by the balance between photosynthesis and respiration. Unders…

New Open Access paper from the NERC SPLICE project, which examines how modelled predictions of photosynthesis change as the 3D description of the canopy becomes more complex. Led by Meg Stretton, with @kungphil.bsky.social and @matdisney.bsky.social.

Same plot as before but with the SSP CO2 concentration data. This doesn't feel quite so dramatic given that we are mostly under the curve, but obviously what's not great is the extent to which we have closed that gap in the last 3 years.

Every so often, over on the other site, I used to post a plot of CO2 concentration at Mauna Loa against the old RCP data. I haven't done that for probably 3 years, so thought I'd quickly re-run my scripts. Looks like we're slowly drifting away from 2.6 & 4.5. Will add SSP data when I get a moment.

Oh wow. Thanks Katherine!

So this is where everyone went! :-)
