IFS manuals for

IFS - Cycle 38r1.

OpenIFS is based on IFS Cycle 38r1 (operational model introduced December 2012).

Manuals (PDF)

all model cycles

IFS manuals are available here.

The manuals on 'Dynamics & Numerical Procedures

', 'Physical Processes

' and 'Technical & Computational Procedures

The PDF manuals are also available for download (together with a web based
source code browser) from the OpenIFS ftp site.

The full list of IFS 38R1 manuals is available, though not all are relevant for OpenIFS.

' are the ones most appropriate for OpenIFS.
