Meteorological Monitoring<br />

Meteorological monitoring will be conducted only when environmental restoration activities dictate. A<br />

meteorological station shall be set up at a designated site to provide continuous recording of<br />

meteorological parameters applicable to atmospheric transport and dispersion of air contaminants. At<br />

field sites that are immediately adjacent to the Albuquerque International Airport/Kirtland AFB flight<br />

facilities, meteorological data provided by the Airport can be used to establish the atmospheric<br />

conditions at the subject sites, provided that the data meets the QA/QC levels required by the dispersion<br />

models and includes the necessary model parameters. At Kirtland AFB locations either in remote areas<br />

or at Interservice Nuclear Weapons School sites, where thorium hydroxide sludge was spread on the<br />

ground to resemble a nuclear weapons accident, meteorological instruments employed on 10 meter<br />

towers should be used to characterize the meteorology of the sites.<br />

The four basic parameters normally monitored include wind speed and direction, ambient temperature,<br />

and sigma theta (used as an indicator of atmospheric stability). At those sites where the soil may contain<br />

a significant amount of volatile compounds, the station will include sensors for recording soil<br />

temperatures and solar radiation. Both parameters may be used to estimate source emission terms of<br />

hazardous air contaminants.<br />

The onsite meteorological system will provide several functions. These include:<br />

Provide real-time data to be used in siting of upwind (background) and downwind samplers.<br />

Provide a data record to indicate the variability of wind flow from suspected sources to air<br />

samplers during the sampling period.<br />

Provide a data record to estimate atmospheric dilution rates and meteorological effects on<br />

source strength during the sampling period and.<br />

Provide real-time data to be used by the Site Health and Safety Officer to estimate<br />

atmospheric diffusion of air emissions, to ensure the safety of on and offsite personnel.<br />

Meteorological parameters to be collected include:<br />

Wind speed to indicate the potential degree of dust suspension<br />

Wind direction to indicate the direction of the potential wind transport mechanism<br />

Precipitation to assess soil moisture conditions<br />

Stability to indicate onsite stability for dispersion of contaminants<br />

Barometric pressure to indicate corrections of flow rates to standard temperatures and<br />

pressure<br />

Ambient air temperature to indicate the potential of volatile suspension<br />

Calibrations will be performed in accordance with manufacturers‘ recommendations. All calibrations<br />

and system checks must be properly documented. The meteorologist will also insure that all strip charts<br />

are properly labeled and will perform data reduction after the completion of the monitoring program.<br />
