2-8: The Instrument Climate Record, Uncertainties

Importance of this Unit to the Course

To provide a basis for evaluating the quality of climate models described in previous units and to understand the impact of changes in precipitation and temperature to be discussed in block 3, we need very complete and accurate long term measurements of the temperature and precipitation across the Earth. This unit provides information relating to the amount and quality of these measurements.
