ORCAS Merge Products
Listed in National Center for Atmospheric Research
This dataset contains merge products for the measurements collected by the NSF/NCAR GV HIAPER (Gulfstream-V High-performance Instrumented Airborne Platform for Environmental Research) aircraft (Tail Number N677F) during the ORCAS (O2/N2 Ratio and CO2 Airborne Southern Ocean) campaign.
Description
The files contain data for all flights for a variety of measurement subsets and averaging intervals. The types of data collected in the project include 1) high-rate (~ 1 Hz) in situ measurements from many instruments, 2) in situ gas-chromatography (GC) measurements on samples collected over a short (~ 30 sec) period of time but spaced by several minutes from the TOGA instrument, 3) laboratory measurements on whole air samples collected in pressurized metal canisters over short (~ 10-20 sec) periods of time by the AWAS sampler, and 4) laboratory measurements on whole air samples collected in continuously flowing glass flasks with longer (~ 30 sec) volume mixing times by the Medusa sampler.
The wide range of representative sample times and the unique nature of each measurement system necessitate several different merged data products.
