NOAA National Weather Service (NWS) radars across the U.S. are in the process of being upgraded with dual-polarization technology that can detect the difference between rain, sleet, snow, and hail.\u00a0 The algorithm sorts dual-polarized radar data into types of liquid or frozen precipitation to help forecasters quickly assess a precipitation event and better forecast how much will fall.<\/p>\n<p>To help evaluate and refine the algorithm, the mostly student-run NSSL\/CIMMS <a title=\"http:\/\/ewp.nssl.noaa.gov\/projects\/shave\/\" href=\"http:\/\/\">Severe Hazards Analysis and Verification Experiment (SHAVE)<\/a> started collecting winter weather precipitation reports through phone surveys during the week of February 3, 2012.\u00a0 SHAVE reports, when combined with the voluntary reports collected by the NWS, creates a unique and comprehensive database of winter weather weather events used to evaluate algorithm performance.\u00a0 SHAVE previously had been a primarily summer project, collecting more than 45,000 reports of hail size, wind damage and flash flooding since it began in 2005.<\/p>\n<p>NSSL\u2019s <a title=\"http:\/\/www.nssl.noaa.gov\/projects\/winter\/\" href=\"http:\/\/\">Precipitation Identification Near the Ground (PING)<\/a> project requests public precipitation reports at\u00a0 http:\/\/www.nssl.noaa.gov\/projects\/winter\/\u00a0 from any area within 90-miles of a radar upgraded with dual-polarization radar technology. Researchers compare the reports of precipitation with what is detected by the dual-polarized radar data.\u00a0 Volunteers have submitted more than 5,000 reports of snow, ice pellets, drizzle and rain since the beginning of the project in 2006.<\/p>\n<p>Both projects are ongoing.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>NSSL is now collecting two types of winter weather reports from the public to help evaluate the performance of a new winter weather precipitation algorithm.<\/p>\n","protected":false},"author":38,"featured_media":1443,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_eb_attr":"","ghostkit_customizer_options":"","ghostkit_custom_css":"","ghostkit_custom_js_head":"","ghostkit_custom_js_foot":"","ghostkit_typography":"","footnotes":""},"categories":[5,11],"tags":[109,172,224,336,533],"class_list":["post-1442","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-outreach","category-radar","tag-dual-pol","tag-hca","tag-issue-januaryfebruary-2012","tag-nssl","tag-winter-weather"],"acf":[],"wps_subtitle":"","_links":{"self":[{"href":"https:\/\/inside.nssl.noaa.gov\/nsslnews\/wp-json\/wp\/v2\/posts\/1442","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/inside.nssl.noaa.gov\/nsslnews\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/inside.nssl.noaa.gov\/nsslnews\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/inside.nssl.noaa.gov\/nsslnews\/wp-json\/wp\/v2\/users\/38"}],"replies":[{"embeddable":true,"href":"https:\/\/inside.nssl.noaa.gov\/nsslnews\/wp-json\/wp\/v2\/comments?post=1442"}],"version-history":[{"count":0,"href":"https:\/\/inside.nssl.noaa.gov\/nsslnews\/wp-json\/wp\/v2\/posts\/1442\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/inside.nssl.noaa.gov\/nsslnews\/wp-json\/wp\/v2\/media\/1443"}],"wp:attachment":[{"href":"https:\/\/inside.nssl.noaa.gov\/nsslnews\/wp-json\/wp\/v2\/media?parent=1442"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/inside.nssl.noaa.gov\/nsslnews\/wp-json\/wp\/v2\/categories?post=1442"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/inside.nssl.noaa.gov\/nsslnews\/wp-json\/wp\/v2\/tags?post=1442"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
