|back to NOTES||January 12, 2000 Meeting
at RAA Board Room
The meeting was started at 7:50. An attendance list is included with these notes.
After those present introduced themselves, Bill Willkie of LFA began to answer the questions that a subcommittee of the Monitoring Committee had given LFA on December 2,1999. (The memo to LFA is included with these notes.)
Please explain why the Lmax points that are graphed dont seem to match those in the raw data in some cases. Here is a specific example:
Site 1-National Turnpike, on 6/3/99 at 12:00
Bill said that, if there were any discrepancies, that these were errors. He said that the graphs were drawn by people taking data from spread sheets and its possible that some errors could occur.
What is the difference in the interval report and the exceedance report and which is plotted in the graph?
The exceedance report lists all events that exceeded the threshold. He wasnt sure about the interval report, but will get back to us. He said the table listed all events that could be positively matched with an event in the ARTS data. If an event wasnt matched, it was usually because the source could have been more than one plane.
Why would some monitored Ldn values be above or below the INM predicted values?
This question had already been covered.
What kind of correlation does it take for the monitored values to verify the INM?
Values of +/- 5 db in 65 Ldn contour.
Is there a statistical variation around each contour line?
There is no statistical variation around a contour line.
Why does the 2005 map contour not take monitored data into account?
You cant monitor for 2005. The question was withdrawn.
Is there a way that Lmax is calculated into overall analysis?
Lmax and SEL are looked at and considered as supplemental information.
Bill agreed to answer these questions at the end of Study Group Meeting #4 for anyone who is interested.
