Long-term Records for Climate Understanding
SPARC promotes activities to guide construction, analysis, and interpretation of CDRs that require international cooperation. For example, merging ground-based, balloon, aircraft, and space-based measurements and accounting for the spatial and temporal sampling characteristics of each measurement type.
- What are the vertically and spatially resolved trends in SPARC-relevant ECVs?
- What are the requirements on observing programmes, both in terms of measurement uncertainties and measurement sampling regimens, such that these observing programmes can reliably detect and quantify trends?
- Which species and state variables are needed, and with what resolution, frequency, and uncertainty, to better diagnose those changes in atmospheric composition and dynamics relevant to SPARC research?
- Is the atmosphere, both in terms of chemistry and dynamics, evolving in a way that is consistent with our understanding?
- What is the temporal evolution of global and regional forcing of the climate system, considering both natural and anthropogenic forcing?
- To what extent do current observations test our knowledge of atmospheric composition and dynamics? Which observations would provide more robust tests of our current level of understanding?
