Dr Sara Mikaloff-Fletcher

Biography

My research focuses on using greenhouse gas observations from ground-based stations, aircraft, ships and satellites to quantify greenhouse gas emissions. In particular, I'm interested in quantifying greenhouse gas emissions and carbon uptake by the land biosphere at urban, regional and national scale to support climate mitigation and policy. I lead NIWA's Changing Atmosphere Flagship Programme, which focuses on measurements and modelling of gases linked to climate change, atmospheric chemistry, and ozone depletion. In addition, I am the Science Leader for New Zealand's MethaneSAT Science Programme, a multi-institutional research programme focused on mapping agricultural emissions around the world from satellite data.

Scientists discover abrupt increase in CO2 uptake by the land biosphere

News article

12 July 2012

Scientists have discovered an abrupt increase in the uptake of atmospheric carbon dioxide by the land biosphere since1988. Without this natural increase in uptake, the amount of carbon dioxide in the atmosphere would probably have increased even more rapidly over the last two decades.
