Two comma-separated values (*.csv) files providing mineral dust mass and number concentrations measured by the PALMS instrument combined with AMP aerosol size spectrometers based on the method of Froyd et al. PALMS In Situ Dust Aerosol Concentration Measurements NetCDF files conform to the NetCDF Climate & Forecast Conventions. Also included are three companions files in comma-separated values (*.csv) format. There are 128 data files included in this dataset: 61 in comma-separated values (*.csv) and 67 in NetCDF (*.nc) formats. Spatial Resolution, Temporal Coverage, Temporal Resolution: File groupings are described in Table 1. Flights circumnavigate the globe, primarily over the oceans. This work was supported by NASA awards NNH15AB12I and NNX17AG31G, NOAA climate funding, the second Tibetan Plateau Scientific Expedition and Research Program (STEP, 2019QZKK0604), the National Science Foundation, the Austrian Science Fund’s Erwin Schrodinger Fellowship J-3613, NASA's Modeling, Analysis and Prediction (MAP) program, the NASA High-End Computing (HEC) Program through the NASA Center for Climate Simulation (NCCS) at Goddard Space Flight Center, and the MAP-funded Chemistry-Climate Modeling (CCM) project (600-17-6985). The ATom mission was supported by NASA’s Earth System Science Pathfinder Program EVS-2 funding. Flightpath (location and altitude) data for each of the four campaigns provided in KML and CSV formats.ATom: Aircraft Flight Track and Navigational Data. Data from all ATom instruments and all four flight campaigns, including aircraft location and navigation data, merged to several different time bases.ATom: Merged Atmospheric Chemistry, Trace Gases, and Aerosols, Version 2. In situ dust aerosol concentration measurements by the PALMS instrument during ATom campaigns.
ATom: Measurements from Particle Analysis By Laser Mass Spectrometry (PALMS). Dominant role of mineral dust in cirrus cloud formation revealed by global-scale measurements. Flights occurred in each of four seasons over a 4-year period.įroyd, K.D., P. ATom deployed an extensive gas and aerosol payload on the NASA DC-8 aircraft for a systematic, global-scale sampling of the atmosphere, profiling continuously from 0.2 to 12 km altitude. It studied the impact of human-produced air pollution on greenhouse gases and on chemically reactive gases in the atmosphere. The Atmospheric Tomography Mission (ATom) was a NASA Earth Venture Suborbital-2 mission.
These data have been applied to better understand the role of mineral dust in cirrus cloud formation. Measurements were made aboard the NASA DC8 aircraft during the four ATom campaigns that occurred from 2016 to 2018 (2) Model output of dust and meteorology from the CESM global transport model extracted at the time and location of the aircraft (3) Model output of dust, other aerosol, and meteorology from the GEOS global transport model extracted at the time and location of the aircraft (4) CESM model global output of dust and meteorology for dust emitted by specific source regions (5) NCEP Global Forecast System forward trajectories of air parcels initiated at the time and location of the aircraft and (6) The location and properties of cirrus clouds formed along the forward trajectories simulated using a parcel model. This dataset provides: (1) In situ dust aerosol concentration measurements over remote tropical Pacific and Atlantic Oceans by NOAA Particle Analysis by Laser Mass Spectrometry (PALMS) airborne single-particle mass spectrometer combined with Aerosol Microphysical Properties (AMP) aerosol size spectrometers.
