DESCRIPTION:Evaluating Precipitation Forecasts from a High-Resolution Ensem
 ble Kalman Filter (HReNKF) Over the Pacific Northwest\n\nAbstract\n\nThe P
 acific Northwest endures some of the heaviest precipitation on the planet 
 - parts of this region receive more than three meters a year. Therefore\, 
 producing accurate precipitation forecasts for these areas is essential to
  warn different sectors of society of the timing and intensity of precipit
 ation events. However\, forecasting precipitation remains difficult as it 
 is a chaotic and non-linear process\, and is even harder over regions of m
 ountainous terrain. In addition\, observational precipitation estimation i
 s difficult due to sparseness of rain gauge data and limitations of radar 
 coverage in complex terrain. In an effort to improve current forecasts\, E
 nvironment and Climate Change Canada are developing a HReNKF for ensemble 
 prediction over this region\, with a 2.5km resolution and an enhanced abil
 ity to assimilate observations. To evaluate these forecasts we develop a g
 ridded observational precipitation product that merges radar and rain gaug
 e data\, called 'kriging with external drift'. This verification product i
 s used quantitatively to evaluate the performance of the HReNKF and of a l
 ower resolution (15km) regional ensemble (ReNKF) using a variety of verifi
 cation methods.\n
