| log in | [Western Pacific Aerosol Data] - Inorganic nitrogen content; and nitrate, ammonium, and oxygen isotope composition of atmospheric particulates collected on Changdao Island, China from September 22, 2019 to September 5, 2020 (Collaborative Research: Characterization of Reactive Nitrogen in The North Pacific Atmosphere) | These data include the content of total nitrogen, nitrate isotope (15N), ammonium isotope (15N), and oxygen isotope (17O and 18O) composition of atmospheric particulates collected on Changdao Island, China. Aerosol sampling was conducted from September 22, 2019 to September 5, 2020. A high-volume aerosol sampler (model 2031, Qingdao Laoying Environmental Technology Co) operating at 1.0 m3 min -1 with 25 × 20 cm filters was used. Recognizing the deposition of atmospheric particulates has the potential to understanding the important role of atmospheric deposition to the nitrogen cycle and biogeochemistry in the ocean. These data assess the contribution of atmospheric deposition to inorganic nitrogen and were collected by Dr. Ren Pen (pren@qnlm.ac) at the Ocean University of China.\n\ncdm_data_type = Other\nVARIABLES:\nCollectionTime (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nCollectionPeriod_Hrs (hours)\nTotalAirVolume_m3 (cubic meters (m3))\nParticleWeight_g (grams (g))\nAmmoniumConcentration_ugPerm3 (micrograms per cubic meter (µg/m3))\nNitrateConcentration_ugPerm3 (micrograms per cubic meter (µg/m3))\nNitriteConcentration_ugPerm3 (micrograms per cubic meter (µg/m3))\nDelta15N_Nitrate (parts per thousand (permil) (‰))\nDelta15N_Ammonium (parts per thousand (permil) (‰))\nDelta18Oxygen_Nitrate (parts per thousand (permil) (‰))\nDelta17O_Nitrate (parts per thousand (permil) (‰))\n | BCO-DMO | bcodmo_dataset_948530_v1 | ||||||||||||
| log in | [Western Pacific Hawaii Aerosol Data] - Aerosol composition data of ion concentrations (ammonium, nitrate, nitrite, sodium, chloride, magnesium, calcium, potassium, sulfate); and ammonium and nitrate isotope (15N) of atmospheric particulates collected in Hawaii from March 2021 to August 2022 (Collaborative Research: Characterization of Reactive Nitrogen in The North Pacific Atmosphere) | These data include aerosol composition data of ion concentrations (ammonium, nitrate, nitrite, sodium, chloride, magnesium, calcium, potassium, sulfate), and ammonium isotope (15N) of atmospheric particulates collected on Oahu, Hawaii. Aerosol sampling was conducted from March 2021 to June 2022 and collected roughly every seven days. A high-volume aerosol sampler operating at 1,200 L min-1 with 25 × 20 cm filters was used. Recognizing the deposition of atmospheric particulates has the potential to understanding the important role of atmospheric deposition to the nitrogen cycle and biogeochemistry in the ocean. These data assess the contribution of atmospheric deposition to inorganic nitrogen and were collected by Mitchell Pinkerton at the Ocean University of Hawaii.\n\ncdm_data_type = Other\nVARIABLES:\nSample_ID (unitless)\nDate (unitless)\nCollection_Location (units)\nlatitude (degrees_north)\nlongitude (degrees_east)\nCollectionPeriod_Hrs (hours (hrs))\nTotalAirVolume_m3 (Liter (L))\nParticleWeight_g (milligram (mg))\nAmmoniumConcentration_ugPerm3 (micrograms per cubic meter (µg/m3))\nNitrateConcentration_ugPerm3 (micrograms per cubic meter (µg/m3))\nSodiumConcentration_ugPerm3 (micrograms per cubic meter (µg/m3))\nPotassiumConcentration_ugPerm3 (micrograms per cubic meter (µg/m3))\nMagnesiumConcentration_ugPerm3 (micrograms per cubic meter (µg/m3))\nCalciumConcentration_ugPerm3 (micrograms per cubic meter (µg/m3))\nChlorideConcentration_ugPerm3 (micrograms per cubic meter (µg/m3))\nSulfateConcentration_ugPerm3 (micrograms per cubic meter (µg/m3))\nDelta15N_Ammonium (parts per thousand (permil) (‰))\nDelta15N_Nitrate (parts per thousand (permil) (‰))\n | BCO-DMO | bcodmo_dataset_946741_v1 |
