Seasonal variation in energy and carbon budget over the boundary between taiga and tundra in North-eastern Siberia

Abstract

In Arctic, temperature has increased almost twice the global average rate in the past 100 years. We aim to clarify the land-atmosphere interaction over the boundary between taiga and tundra in northeastern Siberia, where the climate change effect might be remarkable. We have started the energy and carbon budget observation as well as hydro-meteorological observation in Kodack site (77° 33’ 50.4” N, 148° 16’ 1.23 E, altitude 7m), Sakha Republic, Russia, located in taiga-tundra boundary since June 2013. The seasonal variation of energy and carbon budget has been investigated based on our observation.
