The description should include: a. a site map (drawn to scale) that shows tower location and true north with respect to man-made structures, topographic features, and other features that may influence site meteorological measurements b. distances to nearby obstructions of flow in each downwind sector c. measurements made d. elevations of measurements e. exposure or instruments f. instrument descriptions g. instrument performance specifications h. calibration and maintenance procedures and frequencies I. data output and recording systems j. data processing, archiving, and analysis procedures Guidance on a suitable onsite meteorological monitoring program to provide the required meteorological data is presented in Regulatory Guide 1.23. 2. Meteorological data should be presented in the form of joint frequency distributions of wind speed and wind direction by atmospheric stability class in the format described in Regulatory Guide 1.23. A hour-by-hour listing of the hourly-averaged parameters should be provided in the format described in Regulatory Guide 1.23. If possible, evidence of how well these data represent long-term conditions at the site should also be presented, possibly through comparison with offsite data. 2.3.3-5 Revision 3 - March 2007 a. For CP applications, at least one annual cycle of onsite meteorological data should be provided with the application. For OL applications, at least two consecutive cycles (and preferably 3 or more whole years), including the most recent one-year period, should be provided at the time of application submittal. b. For COL applications that do not reference an ESP and for ESP applications, at least two consecutive annual cycles (and preferably 3 or more whole years), including the most recent 1-year period, should be provided with the application. If two years of onsite meteorological data are not available at the time the application is filed, the staff expects that the COL or ESP applicant will provide at least one annual
