Description:
We present an assessment of the trend detection capabilities of ground-based microwave measurements of ozone, focusing on the 20-60 km region. Uncertainty due to variable forward model and calibration errors is 3-5 percent; due to temperature profile errors, 1-2 percent; and due to spectral measurement errors, 1-3 percent. The measurement resolution is 8-10 km below 40 km, and increases to 17 km at 60 km. The net error for trend detection is 4-6 percent. Comparison with other measurements suggests interannual variations can be measured to 3-5 percent. We conclude a trend of 0.5 percent per year would be detected in about 10 years.
