KCBX realized that several weeks of meteorological (raw hourly) data at the North Terminal had faulty temperature readings. There is another onsite measurement of temperature at the same site as the meteorological tower; it’s part of the PM10 instrument.
KCBX replaced the invalid temperature readings with the temperature readings from the PM10 monitor for the six weeks in question and sent the corrected files to EPA.You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.
