\nWe welcome collaborations and are excited about working with others to make discoveries regarding the Fairbanks pollution. If the data are downloaded for the purpose of scientific publication, the UAF group should be informed of the possible use of the data so we can work with the group that is analyzing the data. If the work leads to publishable findings, UAF will work with the collaborating scientists to determine if co-authorship or acknowledgement is appropriate.
\n
\nAll date and time stamps are in UTC and are the starting time an averaging bin (e.g. for an hourly resolution dataset, the data line labeled 18:00:00 UTC contains all data from 18:00:00 to 18:59:59 UTC). The data are filled with "not a number" (= nan) data codes for missing data.
\n
\nAll data from the Alaska Department of Environmental Conservation (ADEC) from the NCORE and A Street regulatory monitors was provided at 5-minute time resolution. At 1-hour and 3-hour time resolution, wind data from these sites was vector averaged, so the column names were changed in the 1-hour and 3-hour files to reflect this fact.
