ENSO related rainfall changes over the New Guinea region

Here we analyze rainfall data for the New Guinea region comprising station observations, reanalysis products and satellite-based estimates in order to better understand some of these details. We find that most gridded products are limited due to their relatively coarse horizontal resolutions that fail to resolve topographic effects. However, the relatively fine resolution TRMM satellite–based product appears to provide reliable estimates and linear correlations between the data and the NINO34 sea surface temperature index provides an insight into the pattern of ENSO rainfall impacts.
