Forests aren't just carbon sinks, they protect people from climate extremes. In the tropics, intact forests cool by 6ยฐC.
But heat from deforestation could reduce safe work conditions for ~3M people & linked to ~28k deaths/yr.

Diving deep into Singapore's water cycle! ๐ฆ From urbanized areas to tropical forests, we've set up experimental catchments across Singapore with friends @ NUS to unravel the hydrological response of these diverse landscapes (incl. water retention in tropical litter layers & isotope sampling)
Another great effort and teamwork from the past #WATSON #COST #Action www.watson-cost.eu to show a pan-European #database of #isotope #data in #soil #water and #xylem in #beech and #spruce #trees.

And thank you @lehmannmm.bsky.social for the efficient leadership!
Last month I got the chance to explain our exciting Waldlabor research in the @revolve.media "Everything is Changing" Podcast -> open.spotify.com/episode/5PtW... (Picture credit: Alessandro Della Bella)
A new dataset on the water quality in Swiss river catchments is now available. CAMELS-CH-Chem incorporates up to 40 water quality parameters for 115 Swiss catchments between 1981 and 2020 ๐ก

The last weeks we spent preparing the AWS for our @cryoscope.bsky.social field campaigns in Ladakh - apologies to my office mates for the mess ๐ Everything is working & the shipment arrived in India. We are excited to start our field campaign soon, stay tuned for updates! @harshberia.bsky.social
Great start of our @cryoscope.bsky.social & @hyclimm.bsky.social collaboration in the beautiful Dischma Valley in Davos. Looking forward to join forces to explore the runoff generation processes in high Alpine environments together!
โ๏ธ Meet CryoSCOPE!
A 4-year EU-funded research project uniting 19 partners across 8 countries to better understand snow, glacier and permafrost processes - how they respond to climate change, and how these shifts affect downstream hydrological and biogeochemical cycles.
Happy to share that if you are interested in large sample hydrology datasets and specifically water quality data you can now check our now officially published dataset:

Why do trees preferably transpire winter precipitation? ๐ณ๐ฆ In our latest commentary we argue that it's not a big surprise but the effect of seasonal differences in soil recharge. onlinelibrary.wiley.com/doi/10.1002/... @canopyinclouds.bsky.social @harshberia.bsky.social @scottallenunr.bsky.social
Successful 3-hr stream sampling during a major weekend storm, will be interesting to trace its signatures in streamflow isotopes. We installed a rain sampler and hosted Zuosinan Chen from @unioulu.bsky.social
You can also see @mfhydro.bsky.social hard at work fixing the pipes
@cryoscope.bsky.social
Five years ago we started with first installations and sampling at our WaldLab Forest Experimental Site! ๐ฒ ๐ง Thanks to all the amazing people that supported me in the last years, enabled us to do exciting research and to @ethz.ch for celebrating the anniversary with this nice article! ๐ฅณ
Excited to start our new EU-Horizon project called "CryoSCOPE" to better understand hydrological partitioning in diverse landscapes with @mfhydro.bsky.social

To what extent do beech ๐ณ and spruce ๐ฒ trees shift their water uptake to deeper layers in dry periods? Can deep roots alone sustain full tree transpiration? Find out out more in Stefanos excellent PhD paper in Tree Physiology, based on root measurements @waldlabor -> doi.org/10.1093/tree...
We invite contributions on experimental and modelling studies that present methodological developments and applications of isotope tracers to improve our process knowledge of water and nutrient fluxes between the subsurface, plants and the atmosphere, across different scales.

Using continuous 3-year soil water isotope sampling in different depths & hillslope locations at "WaldLab" we reveal the mysteries of streamflow generation. Check out our new HESS manuscript: hess.copernicus.org/articles/28/... @usyseth.bsky.social
How much of groundwater seepage & mixing occur around main-river knickpoints? We conducted extensive synoptic sampling, mixing & groundwater modelling to learn more about this in our recent #AGU #GRL publication! So happy to see this paper out: agupubs.onlinelibrary.wiley.com/doi/10.1029/... ๐ฅณ
How much of streamflow in Swiss & Austrian Alpine rivers is younger than 1 month? How is this related to catchment characteristics & hydro-climatical variables?
We answered these questions in our recent @eurogeosciences.bsky.social publication together with BOKU

This is also a proud supervisor moment for myself, I had the honor to guide Maria from first results in her BSc thesis, through hours of fieldwork & data evaluation to the acceptance of an awesome paper! Very well done Maria, it was a pleasure working with you! ๐ฒ๐ณ
To what extent do trees affect nutrient composition of precipitation reaching forest soils? Our recent
publication from WaldLab Zurich led by Maria Grundmann shows seasonal enrichment patterns & we assess potential drivers based on data from 222 rainfall events.

Spent a hot & humid week for fieldwork, discussions and a seminar at NUS Singapore. Great start of our project on runoff generation processes & the role of different vegetation types in tropic urban & semi-urban environments (with Simone Fatichi & his awesome team! ๐)
Last week we had the pleasure to host an international group of students Waldlabor Zรผrich for the 1st edition of the @ethzurich.bsky.social & EPFL Ecohydrology Summer School! Such an amazing group of people, I really enjoyed showing you around & introduce our latest results and sampling efforts!
Thanks to an @ethzurich.bsky.social Innovedum Fund we were able to update our hydraulic lab equipment -> hands-on weir experiments in mini-flumes, a pipe airflow kit & implement data evaluation in Jupyter Notebooks! A huge effort of all staff involved, but totally worth it! ๐๐ #teaching
This week another exciting field measurement class took place at Waldlabor. Our friends from Uni Zurich Ilja van Meerveld & @jansei.bsky.social invited their students to learn about the forest water cycle during challenging but hydrologically interesting weather conditions! ๐ฆโ๏ธ
it was a pleasure to present these findings @eurogeosciences.bsky.social last week!
Winter precipitation is the major source of summer tree transpiration at our WaldLab Zรผrich Forest Site! ๐ฆ๐ณRead more about seasonality signals in soil & xylem waters in our recent Ecohydrology publication: onlinelibrary.wiley.com/doi/full/10....
Happy to share that our litter & deadwood study ๐๐ฆ๐from WaldLab made it to the list of top downloaded Ecohydrology papers! ๐ฅณ onlinelibrary.wiley.com/doi/10.1002/...
