Braker Lane, Suite 200, Austin, Texas 78759<\/p>\n<p>Spaceborne microwave radiometry is the backbone of weather and climate studies. Microwave radiometers can measure a variety of geophysical parameters through clouds and precipitation. When assimilated into weather forecast models, these observations account for a dominant 43% reduction in forecast error, compared to other satellite instruments. While an individual radiometer has a long revisit time of several days and a limited lifetime, a constellation of radiometers can reduce the revisit time to tens of minutes and provide decades of climatological data. Typically, science applications require around one-Kelvin accuracy (0.2% error). Calibration and intercalibration must be carefully conducted to correct various instrument issues and reconcile radiometer biases for subsequent science applications.<\/p>\n<p>This talk presents methods and results of radiometer calibration, intercalibration, and science applications. These methods have been applied to the recent NASA\/JAXA Global Precipitation Measurement (GPM) mission, which consists of a constellation of radiometers to measure global precipitation. The GPM constellation has produced an unprecedented precipitation dataset with high temporospatial resolution (half-hour and 0.1 degree). Examples of solutions for long-standing issues with calibration, coastal science applications, and preliminary results of hydrological studies conducted with GPM data will be given.<\/p>\n<p>Coffee &amp; cookies will be served<br \/>\nFor further information, please contact 471-5573<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speaker John Xun Yang Department of Climate and Space Sciences and Engineering, University of Michigan Time and Place February 19, 2016\u00a0\u2013 Friday\u00a0\u2013 2:30 PM WPR Building, Conference Room 2.806 3925 [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[19],"tags":[],"_links":{"self":[{"href":"https:\/\/utw10640.utweb.utexas.edu\/wordpress\/wp-json\/wp\/v2\/posts\/1653"}],"collection":[{"href":"https:\/\/utw10640.utweb.utexas.edu\/wordpress\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/utw10640.utweb.utexas.edu\/wordpress\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/utw10640.utweb.utexas.edu\/wordpress\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/utw10640.utweb.utexas.edu\/wordpress\/wp-json\/wp\/v2\/comments?post=1653"}],"version-history":[{"count":2,"href":"https:\/\/utw10640.utweb.utexas.edu\/wordpress\/wp-json\/wp\/v2\/posts\/1653\/revisions"}],"predecessor-version":[{"id":1659,"href":"https:\/\/utw10640.utweb.utexas.edu\/wordpress\/wp-json\/wp\/v2\/posts\/1653\/revisions\/1659"}],"wp:attachment":[{"href":"https:\/\/utw10640.utweb.utexas.edu\/wordpress\/wp-json\/wp\/v2\/media?parent=1653"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/utw10640.utweb.utexas.edu\/wordpress\/wp-json\/wp\/v2\/categories?post=1653"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/utw10640.utweb.utexas.edu\/wordpress\/wp-json\/wp\/v2\/tags?post=1653"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
