Presentation Summary: In order to offer to various users continuous spatial coverage of precipitation data, the Canadian Centre for Weather and Environmental Prediction (CCWEP) operates the Canadian Precipitation Analysis System (CaPA) in near real time. CaPA produces an optimal grid-based precipitation estimate by combining three types of data: (i) precipitation sensor readings; (ii) radar estimates; and (iii) test fields generated by a numerical weather prediction system. Four 6-hour cumulative analyses valid at synoptic hours (00, 06, 12 and 18 UTC) and two 24-hour analyses valid at 06 and 12 UTC are generated. These same analyses are available at high resolution (∼ 2.5 km) for all of Canada and at lower resolution (∼ 10 km) for North America. At the CCWEP, CaPA is constantly evolving with the objective of improving the quality and availability of precipitation estimates. The integration of satellite data as an additional source of observations and the creation of the CaPA reanalysis covering the 1980s-present period are among the latest advances in CaPA.
Speaker: Dikra Khedhaouiria is currently working on the CaPA precipitation analysis at the Canadian Centre for Weather and Environmental Prediction (CCWEP). She holds an engineering degree from the École du génie de l'eau et de l'environnement de Strasbourg and a PhD in water sciences from INRS-ETE.
