RAPID-WATCH VALOR project investigated how the inclusion of RAPID-WATCH observations into the 'initial conditions', used to start climate model simulations, can refine predictions of the future climate and, particularly, the future state of the AMOC. This dataset collection contains NEMO, FOAM AND ECMWF Model output. The project developed ways to assimilate the RAPID-WATCH and other ocean observations into ocean models which were then used to produce ocean 'syntheses' - complete data sets of our best guess of past ocean state. Similar syntheses were also produced which exclude the RAPID-WATCH observations. Both of these sytheses were then used to start prediction experiments in climate models. By comparing the climate model simulations starting with and without the RAPID-WATCH observations, the impact of the the RAPID-WATCH array observations on climate predictions, and the climate model AMOC were found.

RAPIT was looking at the problem of estimating the risk of the collapse of the overturning circulation. Using modern statistical methods for the analysis of complex numerical models, large ensembles of two Atmosphere Ocean General Circulation Models (HADCM3 and CHIME) were analysed. This dataset collection contains meteorology, climatology and ocean outputs from ensemble runs xfel, xfgb, xfha and xgym. Studies of large excursions of the strength of the overturning in existing control runs were used to guide the choice of metrics and diagnostics.
