GloDecH is a research program funded by the NOAA Climate Variability and Predictability Program and conducted at the Lamont-Doherty Earth Observatory.  The research program involves a large number of climate scientists at Lamont working on multiple aspects of decadal hydroclimate variability and change including analyses of observations and pre-instrumental records and modeling of past and future climate. 

Overall goals:

Near-term hydroclimate change worldwide (Southwest North America, the Mediterranean - North Africa - Middle East (MENAME) region, southern South America, Europe, the West African monsoon, the Asian monsoon) will be as strongly influenced by natural decadal variability as by radiatively-forced change.

To use instrumental records, pre-instrumental records, long forced and free model simulations, and AR4/5 simulations and projections to 1) characterize the spatial and temporal nature of DecH 2) determine its mechanisms and 3) assess its predictability.

Use this information to prepare probabilistic predictions of near-term hydroclimate change that account for forced change and, realistic natural variability.
