19 Jan, 1996: NCEP Reanalysis Pressure Level Means.

Update, Corrections, New Location: The pressure level monthly means from the NCEP reanalysis are now available from 1985 through 1993. The V winds which suffered from a minor problem due to OUR spectral processing error for 1985-1990, have been corrected. (The NCEP's problems near the poles remain.) This data set has been moved from /CA/NMC/MEANS/ to /CA/NMC/PRESS/.

December 1995: The creation of the CAS data catalog.

The World Wide Web version of the CAS Data Catalog has been gradually constructed throughout 1995. It incorporates all the information found in the old gopher catalog plus more. In a sense, it is all new. On the other hand, the data sets have remained unchanged. In this light, the "What's New" items will initially include changes to the data sets. Eventually it will also include changes to the catalog itself except minor changes as supporting documentation is added.
