Model Assessment • River discharge at 20 stations • Snow depth at 8 stations • Snow water equivalent via surveys at 3 stations • Lake freeze/thaw at 19 lakes • Lake ice depth at 1 location • Soil frozen depth at 1 station • Soil temperature profile at 1 station • Snow areal extent via AVHRR
Global Land-Atmosphere System Study (GLASS) • GEWEX project which aims to encourage the development of a new generation of LSSs by coordinating their evaluation and inter-comparison; • Serves as an interface between the land-surface community and other GEWEX projects.
Assistance for Land-surface Modeling Activities (ALMA) • The section of GLASS which will provide infrastructure and technical support for model inercomparisons. • This includes specification of a stable data exchange format (netcdf with the GDT convention) and procedures to exchange data.
