“The present study assesses the impacts of climate change on blue and green water in the Kessie Watershed of the Ethiopian Upper Blue Nile Basin using the SWAT+ model.
[The authors] set up [a] SWAT+ model using quality-controlled and homogenized observational climate time series… and calibrated it using a multisite calibration approach. [They] selected CMIP6 climate models for future simulations and bias-correction methods through a comprehensive performance assessment... Building on these previous studies, the present research further evaluates the reliability of combining robust climate-model selection with optimal bias-correction methods to improve the reliability of hydrological simulations. [They] then used the best-performing climate models, bias-corrected using the optimal methods, to project future changes in blue and green water in the study area…
KEY FINDINGS:
• SWAT+ effectively represented hydrological processes across multiple gauging stations in the Ethiopian Upper Blue Nile Basin.
• Ensembles of CMIP6 climate models improved the reliability of hydrological simulations compared with individual climate models.
• Optimized climate-model selection reduced biases in hydrological simulations more than bias correction alone.
• Arbitrary selection of climate models can degrade hydrological simulations, even when their outputs are bias-corrected using robust methods.
• Both blue and green water are projected to increase under future climate change in the Ethiopian Upper Blue Nile Basin.
• Blue water exhibits greater seasonality and climate sensitivity than green water flow and green water storage.
The study also provides sustainable water management options for adapting to the impacts of climate change, with implications for water resource planning and management in the Upper Blue Nile Basin…”

Why has GC-MS (gas chromatography- electron impact ioniation- mass spectrometry) had such enduring value for the field of metabolomics? How do we identify metabolites based on mass spectrometry data?

I hope you'll enjoy this video explaining the basics of GC-MS and the spectral library methods we use for explaining these spectra!

Just spent four hours trying to make a leak-free seal between a tank of UHP He and a regulator.

Turns out the seat in the tank was corroded and no matter how tight I attached the regulator, nothing was going to work.

(Luckily my wife suggested I try another regulator, and w/in ten mins of my conversation with her I realized I was on a fool's errand.)

I need a beer. 🍻#GCMS

I spent SO MANY HOURS in grad school manually adjusting peak baselines and deciding what should or shouldn't count as a peak and then going back and doing it all again because I called it a peak in one sample but not the other. I'm SO happy that progress is being made on this problem and very excited to read this preprint!

This morning I have been sitting in a review of our #PolarRES project with EC + an independent scientist.
It's incredibly cool, seeing progress over the last 18 months, some incredible work already done + lots more on the way.

This figure shared by PI Priscilla Mooney struck me again.
What we're trying to do with the very high resolution #RCMs and the stretched grids in the #GCMs is *hard* + never really tried before.

Awesome #outreach plan too

@mosterh1 @team Ja, für die "klink"-Elemente usw. ist das plausibel. Allerdings kann man auch (in diesem Sinne) funktionsfähige Links in dem Seitentext platzieren.

Funktioniert..., ist aber nicht elegant - ein solcher "getrickster" Link wird dann ja nicht unter "Links" - als eigenständigem Design-Element - angezeigt.

Are you an #analytical #scientist based in the #UK? A new #PI who has a #data story to tell? I’m organising a webinar series and want to #invite #speakers to showcase how they look at #big #data. It can be #LCMS #GCMS #NMR other #spectroscopy or any #analytical #data. Interested? Drop me a toot! Pls #boost so I can cross :mastodon: servers and land into them all! :vaccinated_skintone3: :rstats: :python:

My #introduction --
I'm an #atmospheric and #analytical chemist, studying multiphase #chemistry on air-exposed surfaces.

My group at #Bucknell Univ. uses mass spectrometry (#TeamMassSpec), and we are looking to bring #ionmobility techniques more into the environmental chemistry realm.
