The last date of data collection was January 4, 2016. This project measures atmospheric mercury fractions which contribute to dry and total mercury deposition. Proctor Maple Research Center and VMC participate in a network of sites collecting concentrations of atmospheric mercury species from automated, continuous measuring systems coordinated by the National Atmospheric Deposition Program.Gaseous Elemental, Gaseous Oxidized and Particulate-Bound Mercury FluxFlux of gaseous elemental, gaseous oxidized and particulate-bound mercury measured with automated instrumentation at Proctor Maple Research CenterVMC.318.309mySQLhttps://www.uvm.edu/femc/data/archive/project/atmospheric-mercury-network-amnet-continuous-monitoring/dataset/gaseous-elemental-gaseous-oxidized-particulate-bound2013-06-122016-01-04lampV_AvgAverage lamp voltageAverage voltage of the lamp in the analyzer during samplingdecimalmeterrealRECORDRecord numberInstrument-assigned identification number for the recordintmeterintegerT1baselnBaseline voltageBaseline reading emitted by zero air (no mercury)decimalmeterrealT1blnstdBaseline voltage standard deviationStandard deviation of the baseline leveldecimalmeterrealT1eventSample event Code indicating the type of sample (elemental, reactive, particulate) assayedint0GEM1Flush2Pyrolyzer heating3PBM2.5 heating 4GOM heatingT1HgConcSample concentrationConcentration of mercury in the sampledecimalmeterrealTIMESTAMPRecord timestampTime the record was captureddatetimeYYYY-MM-DD hh:mm:sstime_of_yearDay and time of yearDay of year plus decimal representation of hours, minutes and secondsdecimalmeterreal0365TkCartridgeInstrument cartridge sampledThe cartridge within the instrument from which sample was analyzedtextTkDateInstrument dateDate as set on the instrumenttextTkhourInstrument hourHour as set on the instrumentintmeterinteger023TkminInstrument minuteMinutes as set on the instrumentintmeterinteger059TkPeakAreaPeak areaArea under the curve recorded by Cold Vapor Atomic Fluorescence Spectroscopy analysisintmeterintegerTkPeakMaxPeak voltageMaximum voltage obtained during the sample analysis phasedecimalmeterrealTkSmpDurationSample period durationDuration of the sampling periodintmeterintegerTkSmpVolumeSample volumeVolume of the sample analyzedintmeterintegerTkStatusInstrument status codeCode indicating nature of operation of each cartridgetextTkTimeInstrument timeTime as set on the instrumentdatetimeotherTkTypeMode of operationType of operation the instrument ran during time periodtextT_2537A_C_AvgAverage temperature of analyzerAnalyzer's average temperature during samplingdecimalmeterreal
