The evaluation is conducted over China at 0.5\u00b0 spatial resolution against a ground-based gridded China monthly Precipitation Analysis Product (CPAP) from 1983 to 2014 (32 years). The Standardized Precipitation Index (SPI) at various time scales (1 month to 12 months) is calculated for detecting drought events. The results show that PERSIANN-CDR depicts similar drought behavior as the ground-based CPAP in terms of capturing the spatial and temporal patterns of drought events over eastern China, where the intensity of gauge networks and the frequency of droughts are high. 6-month SPI shows the best agreement with CPAP in identifying drought months. However, large differences between PERSIANN-CDR and CPAP in depicting drought patterns and identifying specific drought events are found over northwestern China, particularly in Xinjiang and Qinghai-Tibet Plateau region. Factors behind this may be due to the relatively sparse gauge networks, the complicated terrain and the performance of PERSIANN algorithm.<\/jats:p>","DOI":"10.3390\/rs8050379","type":"journal-article","created":{"date-parts":[[2016,5,4]],"date-time":"2016-05-04T10:07:08Z","timestamp":1462356428000},"page":"379","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":81,"title":["Evaluation of PERSIANN-CDR for Meteorological Drought Monitoring over China"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0036-8879","authenticated-orcid":false,"given":"Hao","family":"Guo","sequence":"first","affiliation":[{"name":"State Key Laboratory of Desert and Oasis Ecology, Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences, Urumqi 830011, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100039, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anming","family":"Bao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Desert and Oasis Ecology, Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences, Urumqi 830011, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6879-4818","authenticated-orcid":false,"given":"Tie","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Desert and Oasis Ecology, Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences, Urumqi 830011, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheng","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Atmospheric Sciences, Sun Yat-sen University, Guangzhou 510275, China"},{"name":"School of Civil Engineering and Environmental Science, University of Oklahoma, Norman, OK 73072, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6997-2818","authenticated-orcid":false,"given":"Felix","family":"Ndayisaba","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Desert and Oasis Ecology, Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences, Urumqi 830011, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100039, China"},{"name":"Faculty of Environmental Sciences, University of Lay Adventists of Kigali (UNILAK), P.O. 6392, Kigali, Rwanda"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2016,5,4]]},"reference":[{"key":"ref_1","first-page":"3","article-title":"Drought as a natural hazard: Concepts and definitions","volume":"Volume 1","author":"Wilhite","year":"2000","journal-title":"Drought, A Global Assessment"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1149","DOI":"10.1175\/1520-0477-83.8.1149","article-title":"A review of twentieth-century drought indices used in the united states","volume":"83","author":"Heim","year":"2002","journal-title":"Bull.
