SPIO-000616http://spdf.gsfc.nasa.gov/pub/data/ariel/ariel3/langmuir_probe/plasma-frequency_electron-temperature_thunderstorm-noiseNMC-Y, DSC-Y ASCIIAll phys.1 files are successfully converted to ascii w minor corruptions and translation errors; One folder has a non-conforming naming convention and contains no files at all.

There are approximately 3 raw files in each folder in pre-ASCII format (approx 45 – 50 total).

The raw files are somewhat large, with many in the range of 3 to 6 Megabytes.

There are 15 folders.

Data is very complex and does not conform to fixed width or other standard.  An attempt is made in the normalization file to show the ASCII converted files hand edited to conform to consistent, reliable normalized data.  These normalized datasets may be consumed by netCDF after extraction from the spreadsheet.
