We estimated precipitation in the target year by training the observed precipitation and FM1 data in a 7 × 7 grid point area centred on the grid point including observed precipitation as ...Satellite precipitation estimates (SPEs) are promising alternatives to gauge observations for hydrological applications (e.g., streamflow simulation), especially in remote areas with sparse observation networks. However, the existing SPEs products are still biased due to imperfections in retrieval algorithms, data sources and post-processing, which makes the effective use of SPEs a challenge ...PDS -based precipitation frequency estimates with 90% confidence intervals (in inches) 1. 1 Precipitation frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS) . Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation ...Not sure how much precipitation occurred in your area? Amounts are listed and plotted below. Note: These files will be updated at 300 pm central time each day. Data is from the local Cooperative Observer Network, CoCoRaHS (Community Collaborative Rain, Hail and Snow Network) and several ASOS (Automated Surface Observing System) sites.NOAA Atlas 14 Precipitation Frequency Data Server. NOAA's Precipitation Frequency Data Server (PFDS) and associated sites provides statistics on rates of rain over various time periods. These data are useful for calculating capacity for culverts and bridges. Watch a brief video on how to use the tool ».Abstract. Radar Rainfall Data Estimation and Use, MOP 139, provides a detailed look at the basic philosophy and principles for estimating and analyzing radar rainfall data and analyzing data. Radar-derived rainfall estimation is one of the most significant recent advances in hydrologic engineering and practice.Although recent advances in weather radar technology has helped to improve our understanding of the microphysics of precipitation as well as better rainfall estimates, there are still many challenges to improve the estimation of precipitation at ground level [9,10,11,12,13,14,15,16,17,18,19]. Rainfall estimation using weather radars can be ...Find out how much rain has fallen—how many gallons have come down from the skies onto your roof, yard, block, or town.The National Weather Service (NWS) uses river forecast models to estimate the amount/level of water flowing through the US Rivers. These models estimate the amount of runoff a precipitation event generates, computes how the water will move downstream, and then predicts the flow of water at a given location (AHPS forecast point) throughout the ...The average R-factor value estimated for India is 1200 MJ-mm/ha/ha/yr, while maximum rainfall erosivity value 23909.21 MJ-mm/ha/h/yr was spotted in the Laitknsew and Cherrapunji region of East Khasi Hills in Meghalaya state, and minimum value of 8.10 MJ-mm/ha/h/yr in the Shahi Kangri mountain region of Ladakh area.The Global Precipitation Measurement (GPM) Core Observatory, launched in 2014 to succeed the TRMM, is the first Space-Bourne Ku/Ka band Dual-frequency Precipitation Radar and provides high and moderate rainfall estimates at a resolution of 0.1°. Accumulated rainfall estimates are recorded on 30-minute, 3-hourly, daily, weekly, and monthly bases.Rain and other forms of precipitation fall from the clouds. When warm air passes over a body of water, it causes the water to evaporate. Once the water rises high enough, it clumps...An active pattern remains in place across the center of the country with additional threats from severe thunderstorms and heavy rainfall. These concerns will remain in place through most of the weekend. An approaching storm across the Pacific Northwest is expected to bring heavy rainfall and strong winds late this weekend.Specifically, IMERG produces observed estimates of precipitation at 0.1° every half-hour globally from 2000 to the present day. (Efforts to extend the starting year to 1998 are ongoing.) This is achieved by gridding the passive microwave (PMW) precipitation estimates—which are more direct and hence high-quality retrievals—and calibrating ...S i ⁎ is the estimated precipitation according to a, b, and observed precipitation. Another simple but effective way was developed by Tian et al. (2009). The approach decomposes total bias (E total, i.e., RB) into three independent components: hit bias (E H), missed bias (−E M), and false bias (E F). Naturally, the sum of these three ...By amount: From highest to lowest By latitude: From north to south. Please note: Data displayed on these charts are not fully quality-controlled. NOAA/ National Weather …Here we develop and implement a new semi-mechanistic downscaling approach for daily precipitation estimate that incorporates high resolution (30 arcsec, ≈1 km) satellite-derived cloud frequency.

1 Introduction. In July 2018, extremely heavy precipitation occurred in Japan, which was officially called the Heavy Rain Event of July 2018 (Tokyo Climate Center, Japan Meteorological Agency, 2018).An active weather front remained over Japan from 5 to 8 July 2018, which resulted in unprecedented heavy rainfall and caused serious flooding over western Japan (Tsuguti et al., 2018).The accuracy of any gridded climatic data sets is as important as their availability for regional climate and ecological studies. In this study, the accuracy of estimated precipitation in central Asia from three recently developed reanalysis data sets, Modern-Era Retrospective Analysis for Research and Applications (MERRA), ECMWF Interim Re-Analysis (ERA-Interim), and Climate Forecast System ...7-hour rain and snow forecast for Minneapolis, MN with 24-hour rain accumulation, radar and satellite maps of precipitation by Weather Underground.First, the STDs of all the EASM metrics are calculated for the 50 simulations from the historical experiments, and then the median values and their 5–95% ranges are estimated. The model generally reproduces the observed variability for 850-hPa meridional wind, precipitation, precipitable water, and 500-hPa vertical velocity.

The Digital Precipitation Array is a format of estimated one-hour precipitation accumulations on the 1/4Lyon-Fedder-Mobarry (LFM) or 4.7625 km Hydrographic Rainfall Analysis Project (HRAP) grid. This is an 8-bit product with 255 possible precipitation values. This product assesses rainfall intensities for flash flood …The estimated rainfall data is compared against the observed rainfall in the artificial rainfall experiment. The study consists of two main parts. Firstly, we investigate the possibility to estimate rainfall from high-resolution SM observations via SM2RAIN-exp, which is an adjusted version of SM2RAIN including the contribution of surface runoff ...…
