Description:
We consider the problem of integrating environmental data from several monitoring systems over time and space. Many different monitoring instruments and analytical techniques have been used to measure ambient air quality due to advances in measurement technology. Quite often, the newer, more reliable measurements are not compatible with the earlier data. For detecting long-term changes and trends in tropospheric ozone, it is desirable to combine the disparate data to form a single time series. We present a method for combining temporally correlated ozone data. A second situation occurred when auxiliary data from a newer, cheaper measurement system was in operation in tandem with the existing network of continuous ozone monitors. We present a method for combining ozone data from two networks with different supports for spatial interpolation in complex terrain.
