Please join us beginning Friday, April 21 for CUAHSI's 2017 Cyberseminar series on Hillslope Hydrology in Earth System Models! ________________________________
As part of the ongoing collaboration between CUAHSI and NCAR land model working group, funded by NSF-INSPIRE, we are conducting a community synthesis to explore the best ways to represent hillslope hydrology in the large model grids in global-scale Earth System Models (ESMs). A call for participation was issued in January, and several themes emerged from the contributions from the community. As planned, we will hold a series of cyberseminars to further explore these themes, formulate a common framework, and provide specific recommendations to ESM developers in the form of a synthesis paper. This five-part cyberseminar series will differ from previous CUAHSI cyberseminars in that the presentation is held at the minimum here, leaving ample time for community input, discussions and debates. Each session will feature two short 10-minute presentations by colleagues who have given more thought on the issues. These short presentations are meant to start and stimulate discussions. Anyone who wishes to present a few slides (2-3) are welcome and encouraged. Please contact Ying Fan (ying...@eps.rutgers.edu<mailto:ying...@eps.rutgers.edu>) if you plan to do so. We will need to upload your slides to CUAHSI beforehand. April 21, 2017 at 12:00 p.m. EDT Where in the world is subgrid heterogeneity and lateral redistribution likely important to ET (and the associated energy/C flux exchange with the atmosphere) over a large ESM model grid? * Elham Rouholahnejad Freund, ETH Zurich and Jim Kirchner, University of California-Berkeley * Andrea Hartmann, University of Freiburg and Thorsten Wagner, University of Bristol April 28, 2017 at 3:00 p.m. EDT What are the basic subgrid units (characterstic hillslopes?), how does water move through each, and how are they connected to streams, floodplains, wetlands? * Pieter Hazenberg, University of Arizona and Xubin Zeng, University of Arizona * Hoori Ajami, University of California-Riverside May 5, 2017 at 3:00 p.m. EDT What are the basic subgrid units (characterstic hillslopes?), how does water move through each, and how are they connected to streams, floodplains, wetlands? (ctd.) * John Volk, University of Nevada-Reno * Lejo Flores, Boise State University and Jim McNamara, Boise State University May 12, 2017 at 3:00 p.m. EDT How do we carry this to the global scale? How many units do we need for each CLM grid in different parts of the world? What are the terrain features to pull out of hi-res DEMs and other global databases to derive parameters for hillslope models in CLM? * Nate Chaney, Princeton University * Jon Pelletier et al., University of Arizona May 30, 2017 at 11:00 a.m. EDT (tentative) A Synthesis * Sean Swenson, NCAR and Dave Lawrence, NCAR on the latest in CLM * Ying Fan Reinfelder, Rutgers University and Martyn Clark, NCAR on synthesis paper outline and writing tasks Cyberseminars will be recorded and posted online for later viewing in our archives at: https://www.cuahsi.org/Posts/Cyberseminars ________________________________ Join Us!
