To view radiosonde data and sub-sampled MSU/AMSU satellite time series, click:
a channel along the top, a radiosonde along the bottom, and a latitude zone along the right.
The summary plot shows linear trends for all radiosonde types and all 4 regions for each channel.
When the summary plot is shown, change channels by clicking on the channel along the top.
These time series have been smoothed using a filter that strongly attenuates variability that occurs on a 4-month timescale or less.
