Log of file additions/changes/deletions in this Lauder_New directory. For more information please contact Water Vapor Project Leader Dale Hurst, NOAA/ESRL/Global Monitoring Laboratory; Dale.Hurst@noaa.gov Data in these files are 0.25-km vertical averages centered on the listed altitudes. For most flights the averages are presented separately for ascent and descent. Water vapor mixing ratio averages based on combined ascent and descent data ("LEV" data) are also reported in the "H2Omr_orig" column. 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. ========================================================================================== LOG ========================================================================================== 2016 JUL 21: Added or updated 4 older flights from 2003.
