Our lab's mission is to understand the links between optical, biochemical and functional traits of vegetation.
Univ. of Helsinki, Finland
Joined August 2016
This week in @Nature, on our long-term field observation in @HyytialaHY, @INAR_fin, @ForestSciences. https://t.co/r3cWDHe8mh. 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! https://t.co/xsLf25pucv
@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

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: https://t.co/mUnwsJEZPq

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

The chl fluorescence emission distribution of whole tree crowns cannot be measured, right? It can at night! New @OptPhotoLab work https://t.co/iYExnWrQ3i

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
