Sea Ice Freeboard in the Ross Sea from Airborne Altimetry IcePod 2016–2017 and a Comparison with IceBridge 2013 and ICESat 2003–2008
Tian, Liuxi; Xie, Hongjie; Ackley, Stephen F.; Tinto, Kirsty J.; Bell, Robin E.; Zappa, Christopher J.; Gao, Yongli; Mestas-Nuñez, Alberto M. (7/11/2020)As part of the Polynyas and Ice Production in the Ross Sea (PIPERS) project, the IcePod system onboard the LC-130 aircraft based at McMurdo Station was flown over the Ross Sea, Antarctica in November 2016 and 2017, with ... -
Seasonal to Interannual Variability of Satellite-Based Precipitation Estimates in the Pacific Ocean Associated with ENSO from 1998 to 2014
Hou, Xueyan; Long, Di; Hong, Yang; Xie, Hongjie (10/11/2016)Based on a widely used satellite precipitation product (TRMM Multi-satellite Precipitation Analysis 3B43), we analyzed the spatiotemporal variability of precipitation over the Pacific Ocean for 1998–2014 at seasonal and ... -
Sensitivity of Distributed Hydrologic Simulations to Ground and Satellite Based Rainfall Products
Chintalapudi, Singaiah; Sharif, Hatim O.; Xie, Hongjie (5/7/2014)In this study, seven precipitation products (rain gauges, NEXRAD MPE, PERSIANN 0.25 degree, PERSIANN CCS-3hr, PERSIANN CCS-1hr, TRMM 3B42V7, and CMORPH) were used to force a physically-based distributed hydrologic model. ... -
Snow Cover Variations and Controlling Factors at Upper Heihe River Basin, Northwestern China
Bi, Yunbo; Xie, Hongjie; Huang, Chunlin; Ke, Changqing (5/26/2015)Snow is an important water resource and greatly influences water availability in the downstream areas. In this study, snow cover variations of the Upper Heihe River Basin (UHRB) during hydrological years (HY) 2003–2013 ... -
Snow Disaster Early Warning in Pastoral Areas of Qinghai Province, China
Gao, Jinlong; Huang, Xiaodong; Ma, Xiaofang; Feng, Qisheng; Liang, Tiangang; Xie, Hongjie (5/12/2017)It is important to predict snow disasters to prevent and reduce hazards in pastoral areas. In this study, we build a potential risk assessment model based on a logistic regression of 33 snow disaster events that occurred ... -
Spatio-Temporal Change of Snow Cover and Its Response to Climate over the Tibetan Plateau Based on an Improved Daily Cloud-Free Snow Cover Product
Wang, Wei; Huang, Xiaodong; Deng, Jie; Xie, Hongjie; Liang, Tiangang (12/24/2014)Using new, daily cloud-free snow-cover products, this study examines snow cover dynamics and their response to climate change. The results demonstrate that the daily cloud-free snow-cover products not only posses the ... -
Spatiotemporal Analysis of Sea Ice Leads in the Arctic Ocean Retrieved from IceBridge Laxon Line Data 2012–2018
Sha, Dexuan; Koo, Younghyun; Miao, Xin; Srirenganathan, Anusha; Lan, Hai; Biswas, Shorojit; Liu, Qian; Mestas-Nuñez, Alberto M.; Xie, Hongjie; Yang, Chaowei (2021-10-19)The ocean and atmosphere exert stresses on sea ice that create elongated cracks and leads which dominate the vertical exchange of energy, especially in cold seasons, despite covering only a small fraction of the surface. ... -
Weekly Mapping of Sea Ice Freeboard in the Ross Sea from ICESat-2
Koo, YoungHyun; Xie, Hongjie; Kurtz, Nathan T.; Ackley, Stephen F.; Mestas-Nuñez, Alberto M. (2021-08-19)NASA's ICESat-2 has been providing sea ice freeboard measurements across the polar regions since October 2018. In spite of the outstanding spatial resolution and precision of ICESat-2, the spatial sparsity of the data can ...
