Sensitivity analysis with R

After last week’s post, I thought it might be useful to have some practical examples of how to do sensitivity analysis (SA) of complex models (like climate models) with an emulator. SA is one of those things that everyone wants to do at some point, and I’ll be able to point people here for code […]

Choosing your next design point

You can use the R package DiceOptim to choose the next point to run your expensive simulator. Here’s a gif of function EGO.nsteps() in action, choosing one point at a time, with an initial design of three points.   It doesn’t behave in exactly the way I expected, putting lots of points in that well […]

Behind the scenes at the new podcast from the Met Office

I’m pretty excited to be part of the regular team for the new Met Office podcast, Mostly Weather. We’re trying to capture a fun, relaxed and hopefully interesting discussion of science, history and little-known facts about weather and climate. I’d like to think that we hit the nerdy-but-accessible sweet spot. We’ve a couple of episodes […]

The best climate science journals (update)

What are the best/most influential/most read/most overrated journals in climate science? This turns out to be quite hard to judge, as climate science these days can seemingly include everything from economics, to biochemistry, and back to psychology. Google Scholar has a list of what it thinks are the best journals in atmospheric science. Here is […]

More ways to win at twitter

Here is a further list of ways to win at Twitter*. Some other ways can be found here. 7. Be heard Demand that your opponent reads everything that you ever wrote, on any subject. If they haven’t, or they won’t, chide them for being ignorant or narrow minded as appropriate. 8. Victim Bully Victim bully. […]

Could we run a twitter poster session?

I’ve been enjoying following the mega-meetup-12k-scientist-strong EGU conference via the hashtag #EGU15. In particular, people are tweeting pictures of and links to their posters, as adverts for other scientists that happen to be on twitter. This got me to thinking: could we use twitter to run an online-only poster session? I really like poster sessions […]

Internal variability in surface temperature and the hiatus

Our paper Quantifying the likelihood of a continued hiatus in global warming is published today in Nature Climate Change. Here is the New Scientist take, the Carbon Brief take, and the Met Office Research News article. Chris Roberts took on a huge task, processing massive amounts of data in the CMIP5 climate model archive, and leading […]
