“…2005 ;Bolch et al, 2012;Hartmann and Andresky, 2013], and the limitations of coarse resolution dynamical models such as Global Circulation Models over complex terrain [Fyfe and Flato, 1999;Mass et al, 2002;Leung and Qian, 2003;Salathé et al, 2008]. A first step toward addressing these challenges has been the development of gridded precipitation estimates derived from a variety of sources such as satellitebased data, i.e., Tropical Rainfall Measuring Mission (TRMM) [Huffman et al, 2007;Yan et al, 2016;Adjei et al, 2016]; reanalysis data, i.e., ERA-Interim [Dee et al, 2011] and the WATCH Forcing Data Era-Interim [Weedon et al, 2014]; and rain gauge-based data, i.e., Climate Research Unit [Mitchell and Jones, 2005], Climate Prediction Center [Xie et al, 2010] and the Asian Precipitation -Highly-Resolved Observational Data Integration Towards Evaluation (APHRODITE) [Yatagai et al, 2012;Xu et al, 2016]. While the proliferation of remotely sensed, reanalysis and merged products has been a positive development for researchers, many studies find that the aforementioned data sets are often inconsistent with each other [e.g., Palazzi et al, 2013;Yatagai et al, 2012;Ménégoz et al, 2013].…”
