This directory contains the table of contents for the three ECMWF research manuals associated with the ECMWF/WCRP dataset. Please email me at joey@ncar.ucar.edu if you need portions of any of these manuals. Include your mailing address and your fax number. The Technical Attachment, which contains a list of model changes since its inception, is also available. Please email me if you would like this document. Include your mailing address. Note that these documents were most recently updated in 1992 (or earlier for some) and the information may not pertain to more recent time periods. We have requested updates from ECMWF, but as of now, they do not exist, but they are working on them. data-assimilation Table of contents of Research Manual 1, which describes the data assimilation scheme used. adiabatic-model Table of contents of Research Manual 2, which describes the adiabatic part of the operational model. physical-param Table of contents of Research Manual 3, which describes the physical parameterization used in the model.
