The lead PI for stage 1 will be Dennis P. Lettenmaier from the University of Washington. The evaluation will focus on simulations conducted over multiple grid cells on decadal time scales, with some point process evaluation at smaller intensive study areas. Different data sets will be available for model forcing, calibration and evaluation in each stage and as such, the specific focus of each stage will be adapted in accordance with the basin hydrology and available data sets. The western part of the basin consists of mountainous terrain and the predominate vegetation is boreal forest with significant bog areas. The basin does not contain permafrost, although seasonal freezing occurs at the higher elevations.
River flows are unregulated.
Routing network and station locations for the Torne River Basin For the Torne application, intercomparison models will be run over approximately 218 grid cells at 0.25o resolution. Model inputs and outputs will be distributed and archived in netCDF format in accordance with ALMA protocols. Evaluation of model performance will be performed in close accordance with the procedures described by Wood et al. Streamflow is a critical factor for comparison, and will be divided into a calibration and evaluation data set. Evapotranspiration will also be evaluated using atmospheric budget computations to the extent possible.
