Greenhouse Gases and Satellite Methods

In Greenhouse Gases and Satellite Methods group, we study the distribution of atmospheric greenhouse gases – mainly carbon dioxide and methane – through both space-based and ground-based remote sensing.

Background shows one month of OCO-2 SIF retrievals in July 2018. Solar-induced chlorophyll fluorescence (SIF) is emission from vegetation in the far-red to near-infrared wavelengths. SIF has proven to be a powerful Gross Primary Production (GPP) proxy especially in large scales but also in short temporal scales. One OCO-2 satellite measurement covers about 1.2 km x 2.25 km.

  • We utilize and develop extensive ground-based greenhouse gas measurements at Sodankylä in Northern Finland.

  • These measurements provide an essential validation source for increasing volumes of satellite observations at high latitudes, e.g.

  • One of our focus areas is to develop methods for satellite-data driven estimations of greenhouse gas sources and sinks.

  • We also investigate and develop mathematical methods for time series analysis, data assimilation, data fusion, and satellite data interpretation, including uncertainty quantification.

  • The group is part of the Academy of Finland Centre of Excellence in Inverse Modeling and Imaging.
