A comparative study of quantitative mapping methods for bias correction of ERA5 reanalysis precipitation data
This study evaluates the ability of different quantitative mapping (QM) methods as a bias correction technique for ERA5 reanalysis precipitation data. Climate type and geographical location can affect the performance of the bias correction method due to differences in precipitation characteristics. For this purpose, ERA5 reanalysis precipitation data for the years 1989-2019 for 10 selected syno...
متن کاملEstimating IDF based on daily precipitation using temporal scale model
The intensity –duration –frequency (IDF) curves play most important role in watershed management, flood control and hydraulic design of structures. Conventional method for calculating the IDF curves needs hourly rainfall data in different durations which is not extensively available in many regions. Instead 24-hour precipitation statistics were measured in most rain-gauge stations. In this stud...
متن کاملErrors in climate model daily precipitation and temperature output: time invariance and implications for bias correction
When correcting for biases in general circulation model (GCM) output, for example when statistically downscaling for regional and local impacts studies, a common assumption is that the GCM biases can be characterized by comparing model simulations and observations for a historical period. We demonstrate some complications in this assumption, with GCM biases varying between mean and extreme valu...
متن کاملEstimating Historical California Precipitation Phase Trends Using Gridded Precipitation, Precipitation Phase, and Elevation Data
Climate change projections for California indicate reduction in the percentage of precipitation that falls as snow, and increase in the percentage that falls as rain, due to warmer temperatures in the future. Previous work has shown overall decreases in rainfall / snowfall ratios for the western US over the last 60 years. Of interest in this study is the quantification of snow/rain ratios for s...
