Environmental Health <br /> Hi Kasey - <br /> Here are the plots of data from the aethalometer at Vernalis School. Note that the <br /> vertical axis of concentrations is only 0 - 10 micrograms, in contrast to the 0 - 50 <br /> scale for the tire fire monitoring site plots. Thus, there is a bit more 'noise' on this <br /> data. There are clear indications of the impact of*some* kind of smoke at the <br /> Vernalis location. Look at the charts for early on Thursday, Friday, Saturday and <br /> Monday mornings. Probably some of this reflects the overnight temperature <br /> inversion - but there wasn't any smoke on early Sunday morning 1. <br /> I will continue to process the files as you send them, and will also put the charts up <br /> on the Web pages at http://www.mageesci.com/Tracy <br /> Note- when sending data files, please change the FIRST LETTER of the 'Tire Fire' <br /> files *from* BCxxxxxx.csv *to* TCxxoaxx.csv - <br /> and change the first letter of the Vernalis data files to VCxxxxx c.csv. <br /> This will make sure that I never confuse the two sets of files, if they all come in on <br /> the same day. <br /> Thanks <br /> Tony Hansen <br />
