ASSESSMENT OF GREENHOUSE GAS DATA SETS ACROSS THE DATA LIFE CYCLE

Researchers and educators are increasingly interested in accessing greenhouse gas data sets and related atmospheric concentrations both for research and active learning activities focused on climate science. This presentation discusses challenges in acquiring greenhouse gas GIS and remotely sensed data for the US and internationally, including discussion of related metadata and data quality issues. Acquisition and use of NASA data sources for mapping atmospheric concentrations of greenhouse gases and the extent of their data curation, discovery systems, and formal publication using persistent identifiers will be discussed. These issues represent a significant challenge in an escience workflow, particularly in reuse and data provenance lineages.
