Merged Profiler/Rawinsonde Sounding Dataset
During the intensive observing period (IOP) of TOGA COARE, a large number of
collocated rawinsonde and profiler wind observations were taken at six
Integrated Sounding System (ISS) sites and Biak, Indonesia. To mitigate
limitations in the rawinsonde dataset due to missing and bad wind
observations, a procedure was developed to combine profiler and sonde winds
to produce an integrated, high quality, upper-air sounding dataset.
In addition to improving the overall quality of the winds, this procedure
eliminates several data gaps in the sonde dataset. For example, below
800 hPa the amount of bad and missing wind data is reduced from about
45% to 20% at the land-based ISS sites.
The organization and details of the merged datasets are described in
Ciesielski et al. (1997). For additional information on how
these merged datasets were created and their impact upon various atmospheric
analyses, one should refer to this publication.
