6.3 Temperature

Temperature is used in calculations to determine 

• plume rise (Section 6.3.1) 


• mixing height (Section 6.5)


• and various surface-layer parameters (Section 6.6).

Unless indicated otherwise, ambient temperature measurements should be used in these calculations. Although not essential, the ambient temperature may also be used for consistency checking in QA procedures. Applications of vertical temperature gradient measurements are discussed in Section 6.3.2.
