A42E:
Methodologies and Resulting Uncertainties in Long-Term Records of Ozone and Other Atmospheric Essential Climate Variables Constructed from Multiple Data Sources I


Session ID#: 11111

Session Description:
We will discuss uncertainties in long-term ozone and climate data records introduced from merging more than one measurement source. Data sources are combined to improve spatial or temporal sampling, or to extend the record in time. Relative offsets and drifts between measurements used in the climate date record introduce uncertainties on top of the measurement error for each individual instrument. Furthermore, individual instrumental records might vary in sensitivity to aerosol interference, sampling regime, spatial resolution, etc. All of these issues can introduce additional errors currently not assessed in analyses of long-term trends from climate data records, thus complicating attempts to confidently quantify long-term changes. This session will discuss prospective approaches for estimating the uncertainties and drifts in atmospheric climate data records constructed from multiple sources.
