Data in these files are 0.25-km vertical averages centered on the listed altitudes.
All averages are based on combined ascent and descent data except for temperature
and all ozone variables that are determined from ascent data only.

ALL FILES IN THIS DIRECTORY WERE PRODUCED ON OR AFTER SEPTEMBER 15, 2015
USING SKYSONDE PROCESSOR VERSION 0.2.5.7 (OR A LATER VERSION).

THE DATA WERE REPROCESSED AFTER APPLYING AN OPTIMAL OFFSET TO THE
RADIOSONDE PRESSURE DATA THAT WAS DETERMINED USING GPS ALTITUDE DATA. 
PRESSURE OFFSETS WERE APPLIED ONLY TO THOSE FLIGHTS WITH GPS DATA.

NOTE:THE FILE HEADERS HAVE CHANGED SIGNIFICANTLY, BUT VARIABLE NAMES 
AND UNITS REMAIN THE SAME. SOME FILES WERE STRIPPED OF POOR QUALITY OZONE DATA.
