FY 2016 ATLAS, T-Flex, BaiLong meteorological sensor comparison test report Freitag, H.P., C. Ning, P. Berk, D. Dougherty, R. Marshall, J.M. Strick, and D. Zimmerman NOAA Tech. Memo. OAR PMEL-148, NOAA/Pacific Marine Environmental Laboratory, Seattle WA, 40 pp, doi: 10.7289/V57942PP, Published online (2016) Meteorological sensors from Autonomous Temperature Line Acquisition System (ATLAS), Tropical Flex (T-Flex), and BaiLong mooring systems were run in a 6-week-long, side-by-side comparison test at the National Oceanic and Atmospheric Administration (NOAA) Pacific Marine Environmental Laboratory (PMEL) in Seattle, Washington, from 30 July to 16 September. Time series were analyzed at the highest common time interval, which was 10 min for most observations. ATLAS data were chosen to be the standard to which T-Flex and BaiLong data were compared. All three systems provided nearly complete data for the test period, all of which were highly correlated with correlation coefficients > 0.95. RMS differences in time series were generally within or near the expected accuracy of the ATLAS system. The largest differences were in wind direction, daytime air temperature, rainfall, and short-wave radiation. Rainfall was infrequent and light during the test period, limiting the comparison to a few relatively low rain events.
