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.

What a forest’s glow can reveal about the impact of environmental change

Nature - Albert Porcar Castell runs a small outdoor laboratory to draw connections between red-light fluorescence and gas exchange.

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? ➜ @PaulinaRajewicz

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/…

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 works by transforming panoramic imagery to a fish-eye type projection in the comfort of the web-browser using the excellent @pyodide. Find out more here cano.fi/

Canofi is a work in progress (source code on GitHub) improvements and suggestions welcome via info@cano.fi
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

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

Leaf-Level Spectral Fluorescence Measurements: Comparing Methodologies for Broadleaves and Needles

Successful measurements of chlorophyll fluorescence (ChlF) spectral properties (typically in the wavelength range of 650–850 nm) across plant species, environmental conditions, and stress levels are...

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
