PLATFORM: NASA DC-8 airborne laboratory.
LOCATION: Recife, Brazil to Terceira, Azores
ASSOCIATED_DATA: See espoarchive.nasa.gov/archive/browse/atom
INSTRUMENT_INFO: Non-size selected ("bulk") aerosols are sampled isokinetically through forward facing aerosol inlet onto a teflon filter.  Ions are extracted off of the filter into deionized water and ion chromatography analysis is performed.
DATA_INFO: Time data are reported in seconds after midnight UTC. Reported under STP (273 k & 1013 mb)
Do not use these data on time scales shorter than those reported here.
DM_CONTACT_INFO:eric.scheuer@unh.edu
PROJECT_INFO: ATom-4
STIPULATIONS_ON_USE: See the NASA ATom data protocol.
OTHER_COMMENTS: N/A
UNCERTAINTY: Mixing ratios are corrected for the amount of analyte found in extracts of blank (non-exposed) filters. Negative values are reported when an ion is quantified in a sample extract but the amount is less than the deployment averaged background. -8888 is used if when it was not possible to quantify the amount of a given ion in a sample extract.
