Fotosynteesin mittaus alkoi - Photosynthesis measurement is on

Kotovaaran Smear-asemalla käynnistettiin vuoden 2007 fotosynteesin mittaus, viikkoa aikaisemmin kuin edellisenä vuonna. Vaikka metsässä on lunta vielä 60-70 cm, lumesta puhdistuneet männyt sieppaavat runsaassa kevään valossa jo ilman hiilidioksidia. Lämpötila on 2-5 astetta nollan yläpuolella. Kuvan kyvetin taustalla näkyy Sauoiva (615 m).

Photosynthesis measurements of 2007 were initiated in Kotovaara Smear station, one week earlier than in 2006. Although there is a snow cover of 60-70 cm in the forest, the trees are free from snow. As there is plenty of spring light available and the temperature is above zero (typically 2-5 degrees), carbon dioxide capture in the cuvettes is already clearly measurable. The fell far behind the cuvette is Sauoiva (615 meters above sea level).
