MethaneSAT

Detecting and quantifying methane emissions by satellite. The core mission of this unique satellite is to support reductions in methane emissions around the world, primarily by reducing leaks from oil and gas production. NIWA's Dr Sara Mikaloff Fletcher is leading a science programme to develop capability to map agricultural emissions and determine the best places for the satellite to look for methane emissions around the world.
