Hunting where the ducks are: Regional scale measurements, models, and synthesis of concentrations and fluxes of CO2 and CH4
Abstract
Anthropogenic emissions of CO2 and CH4 are strongly concentrated in urbanized and industrialized regions of the United States and around the world. Measuring and interpreting the concentration anomalies in these areas pose a wide range of scientific and engineering challenges. The Carbon Monitoring System (CMS) research program has asked fundamental questions in this area, and yielded enormous progress in understanding and addressing the issues underlying these challenges. This paper uses examples from studies supported by NASA's CMS and closely aligned NOAA programs to examine some key issues and insights. We will focus on the interplay and synergy of bottom-up inventories and top-down emissions estimations. The focus will include: i. the requirement for multi-scale, time-resolved inventories and multi-scale, sustained measurements; ii. the need to distinguish biogenic and fossil fuel fluxes, and ii. the emergence of innovative observational strategies.
