Dr. Angell's focus was on the radiosonde measurements of the atmospheric temperature above the Earth's surface but he also gave results for surface temperature.

In conclusion, the research on radiosonde measurement problems looks promising but it is only a small part of a larger problem of poor measurements and poor models.

The satellite measurements appear to be substantiated by independent trend estimates for this period based on radiosonde data.

However, early radiosonde sensors suffered from significant measurement biases, particularly for the upper troposphere, and changes in instrumentation with time often lead to artificial discontinuities in the data record... Consequently, most of the analysis of radiosonde humidity has focused on trends for altitudes below 500 hPa and is restricted to those stations and periods for which stable instrumentation and reliable moisture soundings are available.
