Seychelles Radiosonde L3 Data (ESC Format) [NCAR/EOL]



This is one of the upper air data sets developed for the Dynamics of the Madden-Julian Oscillation (DYNAMO) 2011-2012 project. This data set includes 320 high vertical resolution (2-second) radiosonde soundings from the Seychelles. The soundings were typically released four times per day (00, 06, 12, and 18 UTC) from 28 October 2011 to 24 December 2011, then twice per day (00 and 12 UTC) from 25 December 2011 to 15 January 2012, and once per day at 00 UTC from 16 January 2012 through 31 March 2012. These data were provided by JAMSTEC and had preliminarly quality control by NCAR/EOL. This L3 version of the data set has had a daytime radiation dry bias correction applied by CSU.
