Abstract
This repository contains data from the relocatable air monitoring system (RAMS) trailer, which measured air pollution around sites in the Fairbanks North Star Borough (FNSB), Alaska. Measured pollutants were: SO2, CO, CO2, and particulate matter (PM). We additionally measured meteorological parameters such as temperatures, winds, and vertical differences in temperatures across an 11-meter tall tower.
Description
Gas and particle data from Fairbanks during the winter of 2019/2020. PLATFORM: Relocatable Air Monitoring System (RAMS) trailer LOCATION: Fairbanks, but varies, see columns in this file AUTHORS: Meeta Cesler-Maloney and William Simpson University of Alaska Fairbanks Chemistry and Geophysical Institute 1930 Yukon Drive, UAF, Fairbanks, AK 99775 email: mvceslermaloney@alaska.edu or wrsimpson@alaska.edu phone: +1 907 474 2436 or +1 907 474 7235 We 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. All 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. All 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. Note that the file lengths, checksums, and number of lines for this release are at the end of this file. --------------------------------------------------------------------------------- Column definitions for RAMS-trailer data files Files are “FNSB-aq-winter-2019-2020-RES-vN.txt” where "RES" is the time resolution (i.e minute, 5minute, hour, 3hour) and N is the release version. — Date index — datetime_UTC -
