Wow!
I'm incredibly proud to share NeuralGCM, our new AI and physics based approach to weather and climate modeling with state-of-the-art accuracy, published today in @Nature:
nature.com/articles/s41586-0…
The Python interface for PDAF is really nice to see, great job!
2 new preprints open for discussion in @EuroGeosciences journals. First is led by @cymjiong on a Python interface to the PDAF data assimilation software (1/2)

Congratulations to everyone involved in the migration!
MeteoSchweiz hat das #Wettermodell #ICON in den operativen Betrieb eingeführt und ersetzt damit das bisherige Modell COSMO. ICON verwendet ein Dreiecksgitter, das eine höhere Auflösung ermöglicht und so die komplexe Topografie der Schweiz genauer abbildet: bit.ly/4cAD6rw

On Friday (15-17 UTC), I will give a talk at the ISDA session on "Machine Learning in Data Assimilation. I'll discuss what impact the AI revolution in NWP could have for DA.
Check link for how to join live. Recording should be on Youtube after.

ECMWF has embraced AI early on. Still the pace is staggering. From raised eyebrows to routine-like operations in what seems little more than five years.
Today we launch an important companion to the #IFS, the #AIFS, our #ArtificialIntelligence/#IntegratedForecastingSystem; a component of our new #MachineLearning project.
Follow our new blog to keep up with ongoing developments to this complementary model➡️ ecmwf.int/en/about/media-cen…
Good morning on day 3! Today will be all about plenary discussion and distilling recommendations. So far, the increasing alignment of surface analyses with atmospheric systems was interesting to see, as well as the increased interest in use of ensembles for surface analyses.
IESWG-5 session on #Land #DataAssimilation hosted 3 excellent talks from @DWD_presse @GernotGeppert, @Metoffice Samantha Pullen and @ECMWF @PRosnay reviewing #LDAS state-of-the-art & the requirements/priorities of these global systems moving towards more #CoupledDataAssimilation
En route now. And looking forward to Helsinki!
Grateful to the Finnish Meteorological Institute #FMI that will host the International Earth Surface Working Group #IESWG that in 2023 officially joined the Coordination Group for Meteorological Satellites #CGMS.

Sadly true. My personal experience is that in particular US-based researchers have reduced their activity. And while I only passively watched/read many conversations, eg in AI/ML for weather and climate, they seem to have ceased nearly completely.

There are two open positions @NCEOscience in Reading, UK. Both challenging, both promising:
- data assimilation and verification for @HydroJules and
- Earth system data assimilation and evaluation of the coupled energy, water and carbon cycles.

This tweet and the linked blog post are well worth reading if you're using pandas and DataFrames with real data, ie. anything that isn't gap-free floats or integers. #Python #data
Pandas 2.0 is here! This is the biggest overhaul of Pandas since its inception, and it has been years in the making. However, you will probably not notice too many changes, and all your existing Pandas code will most likely run the same as before. All the major changes are under the hood. That's because Pandas has moved away from the way it represents data, from numpy to Apache Arrow. Pandas was originally built on top of numpy, and it was an adequate solution for many tasks. However, three are many limitations of numpy that have only become more obvious over the years. Apache Arrow will significantly help with those pain points, and will speed up many Pandas tasks.
I've only played with the new version for a day so far. My limited impression is that it significantly speeds up loading and saving of csv files, and puts the new version of Pandas on par with Polars in that regard. Lookign forward to playing more with it in the weeks and months ahead.
Great blog post about what's new in Pandas: datapythonista.me/blog/panda…

Leider hinter der Paywall aber trotzdem ein schöner Artikel u. a. über die Villigster Förderung @Villigst. Stipendium ist nicht gleich Elite und Evangelisch ist mehr als die Konfession bei den Lohnsteuerabzugsmerkmalen.

Ohh Hamburg meine Perle, du wunderschöne Stadt!
Third time lucky! Finally ran the half marathon after the beast from the east (2018) and COVID (2020) thwarted my plans twice.
But boy was it hot today! Big thanks to everyone with a hose, water gun or spray flask!
