It is a Pre-Workshop In Country Review For Papua New Guinea 19th-23rd October 1999 in Nadi, Fiji Islands. Collaboration between NDMO, PNG NWS and Water Resources
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.
