This week in @Nature, on our long-term field observation in @HyytialaHY, @INAR_fin, @ForestSciences. go.nature.com/4eRyFtv. Collecting key data to understand link between radiation and plant physiology.
We join CREDIBLE action to build carbon farming markets and policies we can trust!
project-credible.eu/
@helsinkiuni takes the lead in the focus group of proximal sensing and digitalization for carbon farming.
Interested in joining the focus group?

Season's greetings from OPL! Tested: 1)Red #Poinsettia leaves absorb PAR but do not fluoresce👉they do not photosynthesize, 2)We have a fluorescent logo😮! No wonder #SIF is great at capturing the optical expression of photosynthesis in its purest state. @ForestSciences,@INAR_fin
Ever wanted to take a hemispherical photo up in the canopy? our new drone method solves this problem...sans hemispherical camera! @NewPhyt
nph.onlinelibrary.wiley.com/…
You can find some more information about the method here www2.helsinki.fi/en/node/111…
Is your hemispherical photography kit weighing you down? Craving spontaneous #forest structure-related fieldwork? Then app.cano.fi/ is for you! Use Canofi to produce hemispherical photos with your phone, no additional hardware required. @PlantSpps @ForestSciences
Canofi is a work in progress (source code on GitHub) improvements and suggestions welcome via [email protected]
We are proud to share our @NaturePlants Perspective on solar-induced chlorophyll fluorescence: what is it? what could it be used for? what are the next steps? Check it out: rdcu.be/ctIOC @INAR_fin @viikki_plants @ForestSciences @SuomenAkatemia helsinki.fi/en/news/carbon-s…
Dancing in the drought. Dynamic canopy structure and foliar physiology are captured by Solar-induced fluorescence (SIF) during water stress. Read our open access paper: doi.org/10.1016/j.rse.2021.1… @INAR_fin @Viikki_plants @AgriForHelsinki @fgi_nls @dronefinland
We simulated the faint glow of #fluorescence in a virtual 3D forest. Check out the open access paper here sciencedirect.com/science/ar… #TLS #LaserScanning #photosynthesis

Check out our new paper (congrats Troy @photo_spec ) showing how well SIF can be used for evergreens: Mechanistic evidence for tracking the seasonality of photosynthesis with solar-induced fluorescence pnas.org/content/early/2019/…

Groundbreaking method from @OptPhotolab to observe from distance the full spectrum of fluorescence of mature trees in the forest. This brings us one step closer to remote sensing of terrestrial carbon sinks and vegetation health. @INAR_fin @helsinkiuni bit.ly/2vY4bD2
The chl fluorescence emission distribution of whole tree crowns cannot be measured, right? It can at night! New @OptPhotoLab work sciencedirect.com/science/ar… #remotesensing #photosynthesis #Fastcam17
Check out new work from @OptPhotoLab member Paulina Rajewicz who measured fluorescence from broad leaves and needles mdpi.com/2072-4292/11/5/532 @RemoteSens_MDPI
Brainstorming sessions today at #FAST2019WS @HyytialaHY around our #Fastcam17 multiscale #fluorescence campaign results. Themes: Molecular/Leaf, Canopy/Ecosystem and Modelling. Trying to find a common language from photosystems to global models. #remotesensing @Suomenakatemia
First impact from our #kärkihankeet #vihreavalo project. Today harvest time! Welcome to pick some potatoes today and tomorrow from Latokartanonkaari 7. @helsinkiuni #viikki #MMTDK
