The picture shows a tripod with a LED-lamp producing the right wavelengths for photosynthesis, hanging underneath it. Below the lamp is a transparent chamber sealed to the ground, connected to a trace gas analyzer from the LI-COR brand. This set-up measures CO2 and CH4 concentrations within the chamber, that are emitted/absorbed by the ecosystem which is boosted by the extra 1000 PAR from the lamp.

Trying out my new set-up in the forest behind my house🌲🏡 The lamp from #heliospectra is increasing the photosynthetically active radiation #PAR on the ground by 1000! Now I can measure #CO2fluxes at different light intensities no matter the weather 🌥️ Looking forward to bring it to the #ArcticTundra!
