These are the files needed for initialization and prescription of the SCM. These data have been derived from Mingha Zhang's variational analysis processing.

- observations are 3-hourly
- files are free-format ascii
- profile data		: 18 layers, from 965-115 hPA, every 50 hPa.
- profile format	: layer pressure decreasing left to right, time increasing top-to-bottom
- first observation	: 1730 UTC 27 Apr 1998
- last observation	: 0830 UTC 18 May 1998
