Uncertainty in the Spatial Interpolation of Urban Rain Gauges Data
Rainfall data is useful in many fields such as urban management, agriculture, and so on. Spatial interpolation is widely used to interpolation continue rainfall data from discrete rainfall gauges. The uncertainty in spatial interpolation is change in different region. Paper focus on urban small area of Beijing city, Xicheng District and analyses uncertainty of spatial interpolation from four as...
متن کاملA Variational Approach to Retrieve Rain Rate by Combining Information from Rain Gauges, Radars, and Microwave Links
Accurate and reliable rain rate estimates are important for various hydrometeorological applications. Consequently, rain sensors of different types have been deployed in many regions. In this work, measurements from different instruments, namely, rain gauge, weather radar, and microwave link, are combined for the first time to estimatewith greater accuracy the spatial distribution and intensity...
متن کاملTesting a Polarimetric Rainfall Algorithm and Comparison with a Dense Network of Rain Gauges
The paper presents an analysis of the performance of different radar algorithms for rainfall estimation. These are the conventional one based on radar reflectivity factor Z and three polarimetric estimators utilizing different combinations of Z, specific differential phase KDP, and differential reflectivity ZDR. A dense micronetwork of 42 gauges in central Oklahoma, USA, is used for validating ...
متن کاملGlobal Precipitation Retrievals Using the NOAA AMSU Millimeter-Wave Channels: Comparisons with Rain Gauges
A surface-precipitation-rate retrieval algorithm for 13-channel Advanced Microwave Sounding Unit (AMSU) millimeter-wave spectral observations from 23 to 191 GHz is described. It was trained using cloudresolving fifth-generation Pennsylvania State University–National Center for Atmospheric Research Mesoscale Model (MM5) simulations over 106 global storms. The resulting retrievals from the U.S. N...
متن کاملCombining meteorological radar and network of rain gauges data for space-time model development
Technological developments and the trend to go higher and higher in frequency give rise to the need for true space–time rain field models for testing the dynamics of fade countermeasures. There are many models that capture the spatial correlation of rain fields. Worth mentioning are those models based on cell ensembles. However, the rain rate fields created in this way need the introduction of ...
