A 10 km North American precipitation and land-surface reanalysis based on the GEM atmospheric model

Abstract: Abstract. Environment and Climate Change Canada has initiated the production of a 1980–2018, 10 km, North American precipitation and surface reanalysis. ERA-Interim is used to initialize the Global Deterministic Reforecast System (GDRS) at a 39 km resolution. Its output is then dynamically downscaled to 10 km by the Regional Deterministic Reforecast System (RDRS). Coupled with the RDRS, the Canadian Land Data Assimilation System (CaLDAS) and Precipitation Analysis (CaPA) are used to produce surface and precipi… Show more

“…Generally, the smaller this value, the more subwatersheds and tributaries will be identified. The meteorologic forcings are provided by the Regional Deterministic Reanalysis System v2 (RDRS-v2; 10 km; hourly; Gasset et al, 2021). The figure shows the mean annual precipitation derived for the 18 years during which the dataset is available and used in this study (2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017).…”

“…In addition to the global products described above, one newer surface reanalysis product that is noted to be of particular interest for transboundary and northern watersheds in North America is the Canadian 10 km North American precipitation and land-surface reanalysis (Gasset et al, 2021). This reanalysis (listed as RDRS_v2 in Table 5) is the result of initializing the Global Deterministic Reforecast System with ERA-Interim and dynamically downscaling the output using the Regional Deterministic Reforecast System (RDRS), coupled with the Canadian Land Data Assimilation System (CaLDAS) and the Canadian Precipitation Analysis (CaPA).…”

“…A 3 arc seconds HydroSHEDS digital elevation model (DEM) (Lehner et al, 2008) and a 30 m North American Land Change Monitoring System (NALCMS) (Homer et al, 2017) landuse/landcover map were used to create the land surface database for the WATFLOOD model. Then hourly precipitation and temperature from a 10 km Regional Deterministic Reanalysis System (RDRS) (Gasset et al, 2021) were used as input into the WATFLOOD model at a 10 km spatial resolution. For modeling purposes, we divided the GL basin in five subdomains: Superior (SUP), Huron (HUR), Michigan (MIC), Erie (ERI) and Ontario (ONT).…”
