28 3.2.2. Site-specific data

29

30 The use of site-specific meteorological data is the best way to achieve spatial

31 representativeness. AERMET can process a variety of formats and variables for site-specific

32 data. The use of site-specific data for regulatory applications is discussed in detail in Section

33 8.3.3 of Appendix W. Due to the range of data that can be collected onsite and the range of

34 formats of data input to AERMET, the user should consult Appendix W, the AERMET User’s

35 Guide (U.S. EPA, 2004c; U. S. EPA, 2012b), and Meteorological Monitoring Guidance for

36 Regulatory Modeling Applications (U.S. EPA, 2000). Also, when processing site-specific data

37 for an urban application, Section 3.3 of the AERMOD Implementation Guide offers

38 recommendations for data processing. In summary, the guide recommends that site-specific

39 turbulence measurements should not be used when applying AERMOD’s urban option in order

40 to avoid double counting the effects of enhanced turbulence due to the urban heat island.

42 3.2.3. Upper air data

43

44 AERMET requires full upper air soundings to calculate the convective mixing height.

45 For AERMOD applications in the U.S., the early morning sounding, usually the 1200 UTC

46 (Universal Time Coordinate) sounding, is typically used for this purpose. Upper air soundings
