Cryospheric Sciences Branch Seminar (Code 614.1)

NIWA, Wellington, New Zealand
This preseantation will cover much of the applied climate work currently being done through the National Climate Centre, at NIWA. There are three main areas of work: spatial estimation and mapping of climate, analysing meteorological hazards and crop-growing potential, and delivering climate-based products over the web. Our climate mapping work is based on using the ANUsplin spatial interpolation software, which is also extensively used in Australia. We have produced a vast library of climate surfaces and have initiated a climate mapping service which has proven very popular. All our climate maps are produced using ArcGIS. We also produce daily estimates of several climate parameters for around 11,500 grid points covering all of New Zealand, which we call our "virtual climate stations". These daily data estimates extend back to 1972 for most variables. Building on our capabilities for mapping climate, we have done some very interesting crop-growing potential studies and meteorological hazards analyses. These studies tend to be funded by local and regional government through regional development and civil defense programmes. Lastly, we have recently launched ClimateExplorer, which is a web-based system for delivering climate data-derived products. These products range from climate change scenario maps to regularly-updated line plots for select climate stations showing the accumulated rainfall from the start of the growing season to the current date.
