Notes:

- as of 18 March 2016 the L3.0 are L2 files as no biases were found in the L2 data 

- files for each site have been tarred and gzipped into a single file 

- read_upaL2_eol.f - fortran program to read L3.0 data in EOL format

- KUIL NWS site experienced a power failure and has no data from 12Z 17 Dec. to 12Z 28 Dec. 2015

- The fully QC'ed sounding dataset (L1-L4):
  - Level 1 (all data in common ASCII format)
  - Level 2 (hi-res with APSEN QC processing)
  - Level 3 (checked to see if corrections are needed)
  - Level 4 (hi-res data put 5-hP uniform resolution with QC flags)

- the dropsonde data will be Qc'ed by NCAR EOL 

- the upsodne data will be Qc'ed by CSU
