' Debbie J Muirooney 10/12/2001 04:00 PM ` To: Robert F Pinehot/DEV/AE/DuPont@DuPont, Chris E Shoop/AE/DuPont@DuPont cc: Subject: Met Data used in Modeling F Y I, here is the m et data for the day in question (Novem ber 1 2 ,1 9 9 6 ). You will notice that the hours 19-23 all have a 1 m /s wind speed, and hour 24 has a 0 m/s wind speed. The first five hours of the following day are also at 1 m/s. The zero is especially troubling. It m ay have been an hour where there was no reading, in which case a default of 1 should have been put in. It could very well be that the anomometer was not working at all during this period, or was stuck. W e may have an argument for for "throwing out" this section of data, i.e., ignoring this period. W e 'v e done this before on other modeling jobs with other states. I will talk to our resident meteorologist (Charlie Zarzecki) on Monday to see if he can come up with justification for doing this. Although, I won't know for sure if this would help without running the model with their inputs. There could be other data periods like this one. Debbie November 12 Met D ata.) EID668785
