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

#Hyytiälä has been canofied! app.cano.fi

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

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

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

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

Less than four hours latter :)... 2nd trailer coming tomorrow noon...welcome!

First impact from our #kärkihankeet #vihreavalo project. Today harvest time! Welcome to pick some potatoes today and tomorrow from Latokartanonkaari 7. @helsinkiuni #viikki #MMTDK

Our key funding projects are about to end. Today we learn what the outcome of these 101 projects is! Minister of Education, @sannigrahn emphasizes importance of research to cope with our society's challenges. #kärkihankkeet #vihreavalo @ForestSciences @helsinkiuni

This week multiscale campaign grand finale with @headwall fluorescence imager with guest star @albert_loren from @BrownUniversity, plus canopy Kautsky and night fun 😊. Now time for a rest and some fresh potatoes! #vihreavalo @helsinkiuni @SuomenAkatemia

Can we track midday depression of photosynthesis, and its dependency on water stress, with solar-induced fluorescence?... physiology and/or canopy structure? #vihreavalo @helsinkiuni @SuomenAkatemia

More on potatoes :): today diurnal profiles of PAM F, SIF, thermal, and transpirarion rates on water control and treatment using the lift. Stay tunned for timelapse video! Now lunch time 😊🌞 #vihreavalo

Excellent weather today for quasi synchronous spectral and fluorescence measurements. Plenty of differences between well irrigated and stressed plots at 30C 🌞! With @fgi_nls. #vihreavalo @helsinkiuni @SuomenAkatemia

Lift and plants ready for this week's multiscale measurements...nice view of our potato plants from up here :) #vihreavalo

@hsfi promised exceptional hot week! Looking fantastic for our drought experiments! Although, given the effort we made in preparing the rain shelters it would feel nice to use them 😄! #vihreavalo

this year's drone features DFOV spectrometer system for fluorescence, stabilised with gimbal, and with synchronised RGB video, in collab with @fgi_nls #vihreavalo #remotesensing

At last, day 1 is over :). First reference measurements done! A bit of rain but we will repeat flights tomorrow, hopefully more sun #vihreavalo
