Did different Earth Science communities agree on a definition for Representation Uncertainty? Find out in our workshop commentary! Enjoyed working with @EmmaWoolliams and others from @metoffice @NCEOscience and @NPL on this.

[Dr Emma Woolliams 🛰 🌍💡 ⚖️ @EmmaWoolliams]

Representation Uncertainty in the Earth Sciences - how do the observation, data assimilation and forecast verification and post-processing communities use this term, and can metrology help? See our publication with @NPL @Metoffice @NCEOscience https://t.co/gBIrz38ji9

[Met Office Science @MetOffice_Sci]

We’re hiring scientists & software engineers for our Data Assimilation (DA) team!

DA is the process of combining observational data with output from a numerical model to produce an estimate of initial conditions for a weather forecast.

Apply by Sunday👉https://t.co/gAd8nvcAGT

Want to find out more about errors due to unresolved scales in convection permitting numerical weather prediction?

Check out our new joint @MetOffice_Sci & @UniofReading research published in QJRMS https://t.co/G7oyAvMacB.

Enjoyed working with @hwlean & @DrSarahDance on this!

This ECMWF/EUMETSAT @NWP_SAF Workshop has been great so far. Looking forward to this afternoons presentations and a lively panel discussion! #NWPSAF2020

[ECMWF @ECMWF]

Get set to watch day 3 of the ECMWF/EUMETSAT @NWP_SAF Workshop on the treatment of random and systematic errors in #satellite #DataAssimilation for NWP which focuses on “Observation errors”. Starts 09:00 GMT https://t.co/I5jHJq1Tba #NWPSAF2020

Great memories, of collecting the data for this paper. Oh the excitement when mathematicians venture out of the office! I will never forget the lock gate at Diglis @DrSanitaVetra @jemimatabeart 😂

[Joanne Waller @J_A_Waller]

Very honoured to be awarded the LF Richardson prize from @RMetS. Thanks to all those who made it possible and for all the congratulations 🎉

[Royal Meteorological Society @RMetS]

🏅 Dr Joanne Waller @metoffice receives the LF Richardson Prize for her series of innovative papers reporting significant advances in understanding & implementing new observation uncertainty techniques.

A great collaboration between #UoR and #DWD scientists (including @roland_music and @DrSarahDance ) to quantify uncertainties in radar superobservations. Check out the results in our @MonWeaRev article: https://t.co/nGWdS7ES1J

[Joanne Waller @J_A_Waller]

Is it feasible and beneficial to assimilate dense observations with spatially correlated errors in an operational NWP system? Our new paper has the answer RMetS Journals https://t.co/mbtYsMu9Rm
