AMIP Diagnostic Subprojects

AMIP Diagnostic Subprojects

A list of the AMIP diagnostic subprojects and their scientific foci (current as of September, 1996). Coordination with other World Climate Research Programme initiatives is also noted as appropriate.

SP 7 Intercomparison of hydrologic processes in general circulation models
SP 8 Polar phenomena and sea ice (coordinated with *SIOMP/ACSYS)
SP 9 Validation of high latitude tropospheric circulation in the Southern Hemisphere
