Introduction of group members


Presentation on ICARTT (Brock):

  • Overview of data format and availability for ICARTT
    • Example of asci text files produced
    • Consistent time base
    • File includes a header, txt file, PI information, instrument details, contact details, location details, other associated files, description of data, processing details
    • Data is sequential in time; produce several file with different time frequencies (1-minute, hourly averages, etc.)
    • Data can be used for airborne or ground analyses
    • Data merges: average to same time base
    • Each file name incorporates the date of the start of the flight
    • New versions replace old versions, don’t have public access to all versions only the latest/best version
    • Have a file format checking software to ensure data is submitted in correct format
  • YOPP concern over text file size for model outputs; netCDF would solve this size storage issue
  • Make sure, regardless of file type, that header info is represented in the file so that metadata is properly handled and distributed
  • There are established tools for these file format conversions so don’t need to re-invent the wheel
  • PI’s of measurement would be responsible for getting data into correct format, using existing tools
    • Ingesting data tools from NASA
  • Formatting can always be converted, but need to focus on establishing a consistent time base for all data to be written in
    • Establish consistent time-interval for similar data sets
  • ICARTT can be modified to fit any type of data or measurements

Action Items:

  • Send out ICARTT links to working group members (Brock, Morris)
  • YOPP MODF needs to identify time base and time-interval for data sets (ALL)
  • YOPP at Polar 18 – organize a time to meet (Uttal, Khalsa)
  • Create or edit YOPP documents to include observations as well as model outputs (Uttal, Casati, Morris)
  • Organize meeting to discuss tasks and identifying individuals to complete tasks associated with MODF files (Uttal, Morris,Casati)
