HIPPO Merged 10-Second Meteorology, Atmospheric Chemistry, and Aerosol Data


This data set provides the merged 10-second 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. All of the data are provide in one space-delimited format ASCII file. The 10-second merged data product was derived by combining the NSF/NCAR GV aircraft navigation and atmospheric structure parameters for position, time, temperature, pressure, wind speed, etc., reported at 1-second frequency, with meteorological, atmospheric chemistry and aerosol measurements made by several teams of investigators on a common time and position basis. Investigators reported most continuously measured parameters at a 1-second interval. The 1 second measurements were aggregated with a median filter to 10 seconds. The fast-sample GC and whole air sample measurements reported at the greater than 10 second intervals (15-120 seconds including processing time) were aggregated to the most representative 10 second sample interval. A supplementary file is provided with this product that summarizes the completeness of the reported data values (HIPPO_10s_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 data are provided in one space-delimited format ASCII file.
