Singapore Radiosonde L3 Data (ESC Format)



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 365 high vertical resolution (2 second) soundings from Singapore taken by the Meteorological Service Singapore from 1 October 2011 through 31 March 2012. These data were initially processed by NCAR/EOL into the EOL Sounding Composite format and passed through a series of automated and visual checks. No data were changed during this part of the processing. The L3 version of the data had the NCAR dry bias correction applied to the Vaisala radiosondes. The Graw radiosondes had a procedure applied to make adjustments to the near-surface radiosonde data due to a change in the release procudures. See the readme for more information.
