Title: Aura Validation Workshop


1
AVDC Update
  • B. R. Bojkov and M. R. Schoeberl
  • NASA Goddard Space Flight Center

2
Current Status
  • AVDC opened to users February 10, 2005
  • 154 registered users
  • 1.4 TB total, 100 GB of validation data
  • 405,000 web hits (1,500/day)
  • 50GB web transfers (185MB/day)
  • Web access only http//avdc.gsfc.nasa.gov
  • Access restrictions (data protocol)

3
Available Data
  • Groundbased
  • MSC groundbased data (4,000 daily files)
  • NDSC MWR (1,800 files from NZ, HI awaiting 3
    other sites)
  • Ozonesondes (700 files SHADOZ, CMDL, VU, MSC)
  • Mirror of AVE/INTEX missions
  • Mirror Envisat Cal/Val groundbased archive
  • Supporting data
  • Satellite data SBUV/2, ACE 2.1, OSIRIS

4
Aura data
  • MLS
  • L2 data and L2 station OVP files
  • OMI
  • Station OVP files for OMTO3, OMDOA3, OMNO2 L2
    (460 stations, daily data)
  • Gridded data (TOMS like 1o ? 1.25o)
  • TES
  • L2 IDLSAVE (AVE) and Langley DAAC mirror (20 GS)
  • Exclusive access to Aura provisional datasets

5
FOV Predictions
  • 5-day FOV predictions generated by AVDC
  • HIRDLS, MLS, OMI and TES (global survey)
  • Aqua and Aura sub-satellite tracks
  • Extensively validated and used for AVE
  • Daily 5-day FOV station OVP files generated
    (NDSC, GAW, etc.)
  • Will extend FOVs predictions to 15 days (October)

6
Tools Database
  • Delayed implementation
  • Groundbased HDF files fully searchable
  • Instrument, location, species, PI, etc.
  • Time/geolocation data searches
  • Including groundbased-Aura FOV coincidences
  • To be implemented by November

7
Tools HDF conversion
  • Convert ASCII into AVDC/Envisat HDF
  • Write, read and QA HDF files
  • IDL read/write procedures on-line
  • Linux, OSX and Windows 2000/XP executables to be
    released shortly

8
Tools Miscellaneous
  • Example scripts to automate web downloading of
    data
  • Example IDL procedure to convert datasets
  • Documentation and Howtos
  • Measurement reporting guidelines in preparation

9
Up and Coming
  • More provisional datasets through AVDC
  • 10 OMI L2 products, HIRDLS, TES S/S
  • Continued Aura data subsetting for validation
  • Accelerated collection of GB datasets
  • Accelerated release of tools and documentation
  • Contact AVDC for information
  • http//avdc.gsfc.nasa.gov
