HIPPO NOAA Flask Sample GHG, Halocarbon, and Hydrocarbon Data

Summary

This data set provides a NOAA flask sample oriented data product of meteorological, atmospheric chemistry, and aerosol measurements from all Missions, 1 through 5, of the HIAPER Pole-to-Pole Observations (HIPPO) study of carbon cycle and greenhouse gases. The Missions took place from January of 2009 to September 2011. This data set provides atmospheric concentrations of CO2, CH4, CO, H2, N2O, halocarbon, hydrocarbon, and sulfur-containing trace gases from flask samples collected with the NOAA/ESRL Programmable Flask Package. Flask samples were analyzed on the NOAA/GMD Measurement of Atmospheric Gases that Influence Climate Change (MAGICC) instrument system and the NOAA/GMD GC/mass spectrometric instrument. Results from 1,374 flask samples are reported. For this data set, the flask sample results were joined with selected variables from concurrent 1-second data. The merging was accomplished by first subsetting and then averaging the 1-second observations corresponding to the fill time range for individual flask samples (e.g., UTSTART_M2 to UTSTOP_M2). This data file is better for instrument comparisons than files constructed by inserting flask values at a single mean fill time observation data file. A supplementary file is provided with this product that summarizes the completeness of the reported data values (PFP_meta_summary.tbl). The completeness entries are the number of non-missing observations for each species in the main data file for each mission and in total. The number of observation given for species observations per mission. The data are provided in one space-delimited format ASCII file.
