Precipitation objects for New Zealand

As part of the Bodeker Scientific contribution to the CCII research programme, we have generated precipitation objects that define past (1971-2000) and projected future (1971-2099) changes in precipitation over New Zealand. These objects have been derived for two different precipitation thresholds (0.5 mm/hour and 1.0 mm/hour in each pixel) and from 4 different data sets of hourly precipitation viz.:
  1. The PERSIANN data set . This data set extends from March 2000 to December 2000.
  2. The PERSIANN data set corrected for biases using hourly precipitation data from sites recording precipitation within New Zealand. This data set extends from March 2000 to December 2000.
  3. A regional climate model simulation, provided by NIWA through CCII, where the lateral boundary conditions are provided by ERA reanalyses.
  4. A regional climate model simulation, again provided by NIWA through CCII, where the later boundary conditions come from the HadCM3 atmosphere-ocean global climate model run under the SRES A1 scenario.
