National Weather Service High Resolution 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 903 high vertical resolution soundings from the National Weather Service (NWS) rawinsonde stations at Guam (297 soundings; 6-second resolution) in the Mariana Islands and Yap (267 soundings; 1-second resolution) and Koror (339 soundings; 1-second resolution) both in the Western Caroline Islands. These data were converted into the EOL Sounding Composite format (columnar ascii).

Soundings were typically released twice daily during this period. However, Yap was once daily until 16 November 2011 (and had no soundings from 30 October to 7 November 2011 and from 19-28 March 2012) and Koror had outage problems from 14-22 December.

This data set contains data from 1 October to 31 March 2012 for Yap and Koror and only 1-31 October 2011 and 1 December 2011 to 31 March 2012 data for Guam.
