clouds of extratropical cyclones passing over the windward slopes, high terrain, and lee side of the Olympic Mountains. Observations on the western side of the Olympic Peninsula were concentrated within and near the Quinault River valley, a very wet drainage on the windward side of the Olympic Mountains ( Fig. 1 ). A secondary focus of observations was the Chehalis River valley lying to the south of the Olympic Mountains. On two occasions, when the primary precipitation occurrence was in the Chehalis

). This system is also in the process of testing IMERG precipitation estimates. GFMS couples the Variable Infiltration Capacity (VIC) land surface model ( Liang et al. 1994 ) and the Dominant River Tracing Routing (DRTR) model to form the Dominant River routing Integrated with VIC Environment (DRIVE) modeling system. To establish percentile thresholds for flood detection within the GFMS system, the DRIVE model was run retrospectively for 15 years using the TMPA record to provide a history of water

observed precipitation and gridbox values of the five LSVs across the entire region of China was calculated for all stations and all grid boxes. The results for the Beijing site are shown in Fig. 3a . For the MSLP, the center of the highly correlated areas is located between the lower reaches of both the Yellow River and Yangtze River. This high-correlation zone corresponds to a low pressure system that occurs in boreal summer and is a component of the rain belt that is brought by the summer monsoon

(GPROF surface types 3–5, corresponding to “maximum vegetation,” “high vegetation,” and “moderate vegetation”) or ocean (GPROF surface type 1). The “ocean” classification can include large water bodies, for example, the Great Lakes. Sea ice, arid regions, surface snow cover, rivers, coasts, and precipitation scenes are excluded. Each orbit is divided into 5° latitude bins. Statistics are derived separately for each of these bins that has at least 10 land and 10 water pixels without precipitation

accumulations over a large river basin. As such, for these applications, the random errors are likely to be lower. On the other hand, systematic errors are more pressing as they cannot be removed by statistical methods available to the user. The gauge adjustment, intended to rein in systematic errors, may not be sufficiently resolved to address biases at the pixel level, as it occurs at a monthly time scale over 1° grids. Given the varying performance of each platform, it may be worth investigating whether

it began as snow. CalWater ( Ralph et al. 2016 ) has managed a series of field campaigns along the U.S. West Coast to investigate clouds and precipitation, particularly in relation to atmospheric rivers (ARs). The 2015 field campaign occurred over January–March 2015 and captured several offshore AR events. The first case on 5 February 2015 developed offshore and was analyzed by Fairall et al. (2018) .

al. (2016) revealed that the IMERG product has more skill in representing daily precipitation than the post-real-time Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precipitation Analysis (TMPA-3B42) and the ERA-Interim product from the European Centre for Medium-Range Weather Forecasts (ECMWF) in Iran from March 2014 to February 2015. For the midlatitude region of the Ganjiang River basin in southeast China, Tang et al. (2016b) showed that the detection skill of the Day-1 IMERG

monsoon is especially significant in the southeastern region, where approximately 90% of the annual precipitation occurs during the wet season (from May to October; Yu et al. 2006 ). The ground observations for this study area came from 40 rain gauges in the Tsengwen River basin, where the elevations vary from near sea level to 2540 m. There are 40% of the gauges located below 100-m elevation and 22% of them located above 1000 m. The rest of the gauges are located between 100- and 1000-m elevations
