Book Synopsis NOAA's Role in Space-Based Global Precipitation Estimation and Application by : National Research Council
Download or read book NOAA's Role in Space-Based Global Precipitation Estimation and Application written by National Research Council and published by National Academies Press. This book was released on 2007-03-13 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Oceanic and Atmospheric Administration (NOAA) uses precipitation data in many applications including hurricane forecasting. Currently, NOAA uses data collected from the Tropical Rainfall Measuring Mission (TRMM) satellite that was launched in 1997 by NASA in cooperation with the Japan Aerospace Exploration Agency. NASA is now making plans to launch the Global Precipitation Measurement (GPM) mission in 2013 to succeed TRMM, which was originally intended as a 3 to 5 year mission but has enough fuel to orbit until 2012. The GPM mission consists of a "core" research satellite flying with other "constellation" satellites to provide global precipitation data products at three-hour intervals. This book is the second in a 2-part series from the National Research Council on the future of rainfall measuring missions. The book recommends that NOAA begin its GPM mission preparations as soon as possible and that NOAA develop a strategic plan for the mission using TRMM experience as a guide. The first book in the series, Assessment of the Benefits of Extending the Tropical Rainfall Measuring Mission (December 2004), recommended that the TRMM mission be extended as long as possible because of the quality, uniqueness, and many uses of its data. NASA has officially extended the TRMM mission until 2009.
Book Synopsis Improving Infrared-Based Precipitation Retrieval Algorithms Using Multi-Spectral Satellite Imagery by : Nasrin Nasrollahi
Download or read book Improving Infrared-Based Precipitation Retrieval Algorithms Using Multi-Spectral Satellite Imagery written by Nasrin Nasrollahi and published by Springer. This book was released on 2014-11-07 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis transforms satellite precipitation estimation through the integration of a multi-sensor, multi-channel approach to current precipitation estimation algorithms, and provides more accurate readings of precipitation data from space. Using satellite data to estimate precipitation from space overcomes the limitation of ground-based observations in terms of availability over remote areas and oceans as well as spatial coverage. However, the accuracy of satellite-based estimates still need to be improved. The approach introduced in this thesis takes advantage of the recent NASA satellites in observing clouds and precipitation. In addition, machine-learning techniques are also employed to make the best use of remotely-sensed "big data." The results provide a significant improvement in detecting non-precipitating areas and reducing false identification of precipitation.

Book Synopsis A Deep Learning Framework for Precipitation Estimation from Bispectral Satellite Information by : Yumeng Tao
Download or read book A Deep Learning Framework for Precipitation Estimation from Bispectral Satellite Information written by Yumeng Tao and published by . This book was released on 2017 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compared to ground-based precipitation measurements, satellite-based precipitation estimates have the advantage of global coverage and high spatiotemporal resolutions. However, the accuracy of satellite-based precipitation observations is still insufficient to serve many weather, climate, and hydrologic applications. In the development of a satellite-based precipitation product, the two most important aspects are the provision of sufficient precipitation-related information in the selected satellite data and the use of the proper methodologies to extract such information and link it to precipitation estimates.In this dissertation, a state-of-the-art deep learning framework for precipitation estimation using bispectral satellite information, Infrared (IR) and water vapor (WV) channels, is developed. I explore the effectiveness of deep learning techniques in extracting useful features from the satellite information and demonstrate the value of incorporating multiple satellite channels.Specifically, I first provide a bias reduction model for satellite-based precipitation products using deep learning approaches to demonstrate their capability of extracting additional useful information from the satellite data. I then design a two-stage framework for precipitation estimation from bispectral information, consisting of an initial rain/no-rain (R/NR) binary classification, followed by a second stage estimating the non-zero precipitation amount. In the first stage, the model aims to eliminate the large fraction of NR pixels and to precisely delineate precipitation regions. In the second stage, the model aims to estimate the point-wise precipitation amount accurately while preserving its heavy-tailed distribution. Stacked denoising auto-encoders (SDAEs), a commonly used deep learning method, are applied in both stages.The operational product, Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks Cloud Classification System (PERSIANN-CCS), serves as a baseline model throughout this dissertation. I evaluate performance along a number of common performance measures, including both R/NR and real-valued precipitation accuracy. Case studies focusing on the model's performance for specific events are also included. The experiments show that our proposed two-stage model outperforms original PERSIANN-CCS in different verification periods over the central United States and in large-scale application. Therefore, the two-stage deep learning framework has the potential to serve as a more accurate and more reliable satellite-based precipitation estimation algorithm.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents current applications of remote sensing techniques for clouds and precipitation for the benefit of students, educators, and scientists. It covers ground-based systems such as weather radars and spaceborne instruments on satellites. Measurements and modeling of precipitation are at the core of weather forecasting, and long-term observations of the cloud system are vital to improving atmospheric models and climate projections. The first section of the book focuses on the use of ground-based weather radars to observe and measure precipitation and to detect and forecast storms, thunderstorms, and tornadoes. It also discusses the observation of clouds using ground-based millimeter radar. The second part of the book concentrates on spaceborne remote sensing of clouds and precipitation. It includes cases from the Tropical Rainfall Measuring Mission (TRMM) and the Global Precipitation Measurement (GPM) mission, using satellite radars to observe precipitation systems. Then, the focus is on global cloud observations from the ClaudSat, Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO), including a perspective on the Earth Clouds, Aerosols, and Radiation Explorer (EarthCARE) satellite. It also addresses global atmospheric water vapor profiling for clear and cloudy conditions using microwave observations. The final part of this volume provides a perspective into advances in cloud modeling using remote sensing observations.

Book Synopsis Assimilation of Satellite Based Rainfall Estimates with the Canadian Precipitation Analysis by : Bruce Friesen
Download or read book Assimilation of Satellite Based Rainfall Estimates with the Canadian Precipitation Analysis written by Bruce Friesen and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Canadian Precipitation Analysis (CaPA) produces a gridded product by assimilating data from stations and the Global Environmental Multiscale (GEM) model. This project assesses the performance of the satellite based rainfall estimates for Canada, and the results of their assimilation with CaPA. The satellite based estimates considered are those from the Climate Prediction Center Morphing method (CMORPH) and Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks (PERSIANN). Relative to the Second Generation of Daily Adjusted Precipitation for Canada (APC2), all satellite products are shown to generally underestimate rainfall, however convective events result in an overestimation. Skill scores show that the satellite products possess the most skill for eastern Canada and decreasingly so westward. When assimilated with CaPA, the satellite products express decreased skill for light rainfall and potential improvements for larger events. While central Canada experiences the greatest improvements, all regions benefit the most from June through August.
