This book was released on 2002-12-01 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study compares rain rate measurements from the Tropical Rainfall Measuring Mission (TRMM) satellite to rain rate measurements from rain gauges on open-ocean buoys. The rain gauges are part of the instrument package on the Next Generation Autonomous Temperature Line Acquisition System (ATLAS) buoys in the Tropical Atmosphere-Ocean/Triangle Trans-Ocean Buoy Network (TAO/TRITON) array in the tropical Pacific. The rain rate data from TRMM and 25 buoys are collected from January of 1998 to December of 2001. TRMM's 3G68 product provides instantaneous rain rate data averaged over 0.50 x 0.50 latitude-longitude grid boxes for the TRMM Microwave Imager (TMI), Precipitation Radar (PR), and a combined algorithm (COMB). The buoy's rain rate data are averaged over and reported in 10-minute intervals. Buoy data are compared to 1.00 x 1.00 TRMM area-averaged values centered on each of the 25 buoy locations. The 1.00 x 1.00 boxes are composed of four 0.50 x 0.50 3G68 grid boxes.
Book Synopsis Changes in Tropical Rainfall Measuring Mission (TRMM) Retrievals Due to the Orbit Boost Estimated from Rain Gauge Data by : Jeremy DeMoss
Download or read book Changes in Tropical Rainfall Measuring Mission (TRMM) Retrievals Due to the Orbit Boost Estimated from Rain Gauge Data written by Jeremy DeMoss and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: During the first three-and-a-half years of the Tropical Rainfall Measuring Mission (TRMM), the TRMM satellite operated at a nominal altitude of 350 km. To reduce drag, save maneuvering fuel, and prolong the mission lifetime, the orbit was boosted to 403 km in August 2001. The change in orbit altitude produced small changes in a wide range of observing parameters, including field-of-view size and viewing angles. Due to natural climatic variability, it is not possible to evaluate possible changes in precipitation retrievals from the satellite data alone. We estimate changes in TRMM Microwave Imager (TMI) and the Precipitation Radar (PR) precipitation retrievals due to the orbit boost by comparing them with surface rain gauges on ocean buoys operated by the NOAA Pacific Marine Environment Laboratory (PMEL). For each rain gauge, we compute the bias between the satellite and the gauge for pre- and post-boost time periods. For the TMI, the satellite is biased ~12% low relative to the gauges during the pre-boost period and ~1.5% low during the post-boost period. The mean change in bias relative to the gauges is approximately 0.4 mm day−1. The PR is biased significantly low relative to the gauges during both boost periods. The change in bias is rain rate dependent, with larger changes in areas with higher mean precipitation rates.

Book Synopsis Comparing TRMM-based Multi-Satellite Precipitation Analysis (TMPA) Data with Ground-based Rainfall Data by : Pedro Miguel Mendonça Paramés
Download or read book Comparing TRMM-based Multi-Satellite Precipitation Analysis (TMPA) Data with Ground-based Rainfall Data written by Pedro Miguel Mendonça Paramés and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Satellite-based precipitation estimates has seen an increased use as utility in performing hydrologic analyses in areas of the globe where precipitation data is sparse or non-existent. However few studies have been conducted in order to evaluate the performance of satellite-based precipitation estimates when compared to ground-based observations (rain gauges or weather radar). This report evaluates the TRMM-based Multi-Satellite Precipitation Analysis (TMPA) 3B42 Version 6 rainfall estimates with three sources of ground-based precipitation observations; a low spatial density gauge network, a high spatial density gauge network, and NEXRAD Stage III rainfall data. TMPA data was evaluated visually and statistically at the native satellite pixel scale and basin scale for nine years. TMPA data was also evaluated during ten rainfall events which generated significant runoff within the study basin. Results indicate that TMPA data consistently overestimates rainfall at both spatial scales and poorly correlates with all three ground-based observations. Furthermore, TMPA data suffers from falsely detecting rainfall when ground observations do not detect rainfall and the inability to detect rainfall of lower intensities. However, improvements in the performance of TMPA were shown when analyzed during specific storm events. The findings in this report provide insights on the capabilities and limitations of TMPA data for possible users of the product.

Book Synopsis Satellite Precipitation Measurement by : Vincenzo Levizzani
Download or read book Satellite Precipitation Measurement written by Vincenzo Levizzani and published by Springer Nature. This book was released on 2020-04-14 with total page 797 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a complete overview of the measurement of precipitation from space, which has made considerable advancements during the last two decades. This is mainly due to the Tropical Rainfall Measuring Mission (TRMM), the Global Precipitation Measurement (GPM) mission, CloudSat and a carefully maintained constellation of satellites hosting passive microwave sensors. The book revisits a previous book, Measuring Precipitation from Space, edited by V. Levizzani, P. Bauer and F. J. Turk, published with Springer in 2007. The current content has been completely renewed to incorporate the advancements of science and technology in the field since then. This book provides unique contributions from field experts and from the International Precipitation Working Group (IPWG). The book will be of interest to meteorologists, hydrologists, climatologists, water management authorities, students at various levels and many other parties interested in making use of satellite precipitation data sets.

This book was released on 2023-06-14 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a selection of refereed papers presented at the 6 Specialist Meeting on Microwave Radiometry and Remote Sensing of the Environment held in Florence, Italy on March 15-18, 1999. Over the last two decades, passive microwave remote sensing has made considerable progress, and has achieved significant results in the study of the Earth's surface and atmosphere. Many years of observations with ground-based and satellite-borne sensors have made an important contribution to improving our knowledge of many geophysical processes of the Earth's environment and of global changes. The evolution in microwave radiometers aboard satellites has increased steadily over recent years. At the same time, many investigations have been carried out both to improve the algorithms for the retrieval of geophysical parameters and to develop new technologies. The book is divided into four main sections: three of these are devoted to the observation of the Earth's surface and atmosphere, and the fourth, to future missions and new technologies. The first section deals with the study of sea and land surfaces, and reports recent advances in remote sensing of ocean wind, sea ice, soil moisture and vegetation biomass, including electromagnetic modelling and the assimilation of radiometric data in models of land surface processes. The following two sections are devoted to the measurement of atmospheric quantities which are of fundamental importance in climatology and meteorology, and, since they influence radio-wave propagation, they also impact on several other fields, including geodesy, navigational satellite and radioastronomy. The last section presents an overview of new technologies and plans for future missions.
