Looking forward to the excellent programme of day 2 of our @OxfordAOPP retreat, kicking off with a talk by @OxfordAOPP‘s Tim Palmer!

What is the travel carbon footprint of a big scientific conference like #EGU19? 16,273 scientists from 113 countries emitted 22,300 tCO2e. How to reduce it by more than 90%? Answer: 25% virtual participation and Europe arrives by train. 🖥️🚆 @EGU flyingless #netzero

We are looking for a post-doctoral researcher to work in our dynamic (and fun) Climate Processes group on observational constraints on aerosol-cloud cloud interactions in models across scales as part of the FORCeS project. Interested? (via email) bit.ly/32yPios

ECMWF @s_e_hatfield Awesome talk from @s_e_hatfield with results from collaborative work with Predictability of Weather and Climate @PDueben. Single precision computations once operational in ECMWF #IFS47r2 will realise impressive savings that can be invested in higher vertical resolution of the ensemble forecasting system!

Fast climate models in 16-bit arithmetic? On a #GPU? Doesn't work? Yes it can! New paper on challenges for #16bit floats (or posits!), how to use mixed-precision, rescaling equations &reduced-precision communication agupubs.onlinelibrary.wiley.com/doi/10.1029/20… Everything in #JuliaLang & open-source!

We've been working on stochastic rounding, which is definitely on our wish list for next generation computing! Finally stochasticity baked deeply into weather and climate models! 🌍

16 bit not enough? I doubt it! After 3yrs of emulation, we finally run simulations on real 16-bit hardware at 3.5x the speed! Everyting 👇in Float16 & #JuliaLang and run on Isambard's A64FX - the same Arm processors that power the fastest supercomputer #Fugaku 🗻!

Attending #vEGU21 this year? You've just saved many million kg of carbon by not flying to Vienna 🥳EGU would have emitted 25,000,000 kgCO2 by the end of next week: 26kg every second due to attendees flying in long-haul. The carbon clock is ticking... egu21.eu/about/green_eg…

Our information-preserving compression is in review for Nature Computational Science! What's real information in #climate data?🌍↔️💿Why do large archives store mostly random bits, and how to separate the false from the real information. Preprint doi.org/10.21203/rs.3.… summary 🧵here⬇️ 1/n

Going online: We've built a Paris Olympics Heat Forecast for the #Olympics from ECMWF's data. How hot will it feel? How does wind💨, sunshine☀️ and humidity💦 affect the feels-like temperature in Japan? TL;DR: It's hot, stay hydrated! Follow this account to receive daily updates ⬇️

Heat forecast for #TokyoOlympics2021: Strong winds continue through Tue, Wed and Thu, still reaching 31˚C daily. Heavy rain likely to stop Tue afternoon but some rain still possible on Wed/Thu. Hotter again thereafter! #OlympicGames #Olympics2021 #Tokyo2020

Can a #weatherforecast be used to minimize the risk of heat-illnesses in sport? Short answer: yes, long answer ⬇️⬇️⬇️

🚨Our #newpaper made it to the front cover of nature Computational Science Nature Computational Science 🥳 nature.com/articles/s4358… #openaccess 📖 Data archives are exploding, ECMWF stores 500,000,000 GB📈 but many bits are just noise with no real information. We propose ... 🧵1/4

Hello #BigData world! Our #newpaper is the editor's pick in the current issue of Nature Computational Science Nature Computational Science 🥳 Read it, it's #openaccess. How to make #BigData small again? We found a way, at least for climate data!

4 years, 9 papers (jeez 🤫), 50+ talks, 8 posters, ~5000 github contributions, 6 radio/news interviews, some 4,000km of 🚲commute, uncountable friends and colleagues, too many pints of cider, 35 housemates and 200L of olive oil later, Dr Milan has finally defended his thesis⬇️

🚨Fluid simulations in only #16bits?🚀~4x faster than good old 64-bit double precision (😴boring!) on the #A64FX processor that powers the world's fastest computer Fugaku? Our new paper explains how agupubs.onlinelibrary.wiley.com/doi/10.1029/20… Run in the The Julia Language we squeeze the model ... 1/4

📽️aaaand action! How do you cheat on chessboards using #fluiddynamics? No, what you see is the (probably) first fluid simulation entirely computed in #16bits! Can you spot the difference to 64 bits? No? There's only one: 16 bits is computed ~4x faster saving time⏰ and energy🔋

We now have a global circulation model developed @OxfordAOPP! Not to replace existing forecast models, but as a computational playground to develop and test new ideas! Looking good already 🥳

Soooo cool! ☁️🌧️🌨️

Forecasting heat and feels-like temperatures with ECMWF|s ensemble prediction system - applied to sport events! How can we bridge the gap between tons of forecast data and what users actually need to know? Communication of forecast data is never easy, maybe 👇this is a way?
