However, X-band weather radar is susceptible to precipitation attenuation. This paper presents an X-band attenuation correction method based on the light gradient machine (LightGBM) algorithm (the XACL method), then compares it with the ZH correction method and the ZH-KDP comprehensive correction method. The XACL method was validated using observations from two radars in July 2021, the X-band dual-polarization weather radar at the Shouxian National Climatology Observatory of China (SNCOC), and the S-band dual-polarization weather radar at Hefei. During the rainfall cases on July 2021, the results of the attenuation correction were used for precipitation estimation and verified with the rainfall data from 1204 automatic ground-based meteorological network stations in Anhui Province, China. We found that the XACL method produced a significant correction effect and reduced the anomalous correction phenomenon of the comparison methods. The results show that the average error in precipitation estimation by the XACL method was reduced by 39.88% over 1204 meteorological stations, which is better than the effect of the other two correction methods. Thus, the XACL method proved good local adaptability and provided a new X-band attenuation correction scheme.<\/jats:p>","DOI":"10.3390\/rs15030864","type":"journal-article","created":{"date-parts":[[2023,2,6]],"date-time":"2023-02-06T05:29:05Z","timestamp":1675661345000},"page":"864","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["X-Band Radar Attenuation Correction Method Based on LightGBM Algorithm"],"prefix":"10.3390","volume":"15","author":[{"given":"Qiang","family":"Yang","sequence":"first","affiliation":[{"name":"School of Atmospheric Physics, Nanjing University of Information Science & Technology (NUIST), No. 219 Ningliu Road, Nanjing 210044, China"},{"name":"Anhui Province Key Laboratory of Atmospheric Science and Satellite Remote Sensing, Anhui Institute of Meteorological Sciences, Hefei 230031, China"},{"name":"Shouxian National Climatology Observatory, Huaihe River Basin Typical Farm Ecometeorological Experiment Field of CMA, Shouxian, Huainan 232200, China"},{"name":"Huaihe River Basin Typical Farmland Ecological Meteorological Field Science Experiment Base of China Meteorological Administration, Shouxian, Huainan 232200, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Feng","sequence":"additional","affiliation":[{"name":"Anhui Province Key Laboratory of Atmospheric Science and Satellite Remote Sensing, Anhui Institute of Meteorological Sciences, Hefei 230031, China"},{"name":"Shouxian National Climatology Observatory, Huaihe River Basin Typical Farm Ecometeorological Experiment Field of CMA, Shouxian, Huainan 232200, China"},{"name":"Huaihe River Basin Typical Farmland Ecological Meteorological Field Science Experiment Base of China Meteorological Administration, Shouxian, Huainan 232200, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Guan","sequence":"additional","affiliation":[{"name":"School of Atmospheric Physics, Nanjing University of Information Science & Technology (NUIST), No. 219 Ningliu Road, Nanjing 210044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenyu","family":"Wu","sequence":"additional","affiliation":[{"name":"Anhui Province Key Laboratory of Atmospheric Science and Satellite Remote Sensing, Anhui Institute of Meteorological Sciences, Hefei 230031, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sichen","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Resources and Environmental Engineering, Anhui University, Hefei 230601, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiangyu","family":"Li","sequence":"additional","affiliation":[{"name":"School of Applied Meteorology, Nanjing University of Information Science & Technology (NUIST), No. 219 Ningliu Road, Nanjing 210044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"280","DOI":"10.1175\/1520-0469(1982)039<0280:TMAMSA>2.0.CO;2","article-title":"The mesoscale and microscale structure and organization of clouds and precipitation in midlatitude cyclones.
