The processing of these observations is straightforward, but large gaps in spatial coverage compromise the reliability of global averages, and changes in instrumentation can give rise to spurious trends.
Compared to most datasets of this type (e.g., Jones 1994), this initial release of GHCN was larger and had more detailed spatial coverage.»
If a larger number of stations are chosen to provide spatial coverage, confidence limits would be wider owing to poor data quality.
But use enough weather stations, and your answer is not only better because you have better spatial coverage, but because errors — even pretty large errors — in one of the weather stations probably won't affect your result.
Prior to 1988, the satellite data that Trenberth uses is not available, but it is known that long term records in radiosondes contain large inhomogeneities due to improving observing systems, increasing spatial resolution (but still very little ocean coverage), and the NCEP data in particular contains large model biases.
