Dataset Title

VICGL output for sensitivity analysis

Abstract

Streamflow and gridded hydrological data produced using the VIC-GL hydrology model. Multiple model runs are produced using different parameter trajectories based on the Morris method. A trajectory is defined as a chain of parameter sets where only one parameter is changed by a fraction of its feasible range in each parameter set. Based on the Morris method, VICGL informative parameters are identified for each output: streamflow, evapotranspiration and snow water equivalent.

Purpose

The project aims at developing computationally efficient methods and strategies for large-scale parameter estimation. These methods are to be process-based, computationally efficient and lead to robust realistic and spatially transferable parameters. This project focus on the version of Variable Infiltration Capacity model developed at PCIC (VICGL). This model is forced by the daily gridded PNWNAmet data. This project supports the Geospatial Intelligence theme of the Core Modelling and Forecasting Team.
