Requested ancillary information about the LSS and its integrations in GSWP-2

Model description:

1. List the most recent/important reference(s) for your LSSs.

2. Give the name of your model, as used in the output file names (see Section 3.2.1 of the Implementation Plan)

3. What time step did you use for your LSS?

4. Describe the vertical structure (number and depth of layers, or other methods of discretization) of your LSS for each of the following:

a. Soil moisture

b. Soil temperature

c. Snow

5. How were soil properties (wilting point, field capacity, porosity, hydraulic conductivity, thermal conductivity, etc.) assigned?

a. From provided fields (Table 3)

b. Other (describe)

6. Does your LSS include frozen soil properties:

a. No change in soil moisture treatment below freezing

b. Binary frozen soil moisture (all or none)

c. Fractional water and ice content in the soil

7. Does your LSS include liquid water in the snowpack?

8. What type of sub-grid parameterizations are used by your LSS (what best describes your LSS)?

a. Effective parameters (and which parameters)

b. Tile/mosaic approaches (structure: i.e. multiple columns or many surfaces over a single soil, etc.)

c. Integration using probability distributions (gamma, normal, etc...and for which variables)

d. Some combination of the above (describe)

9. What sub-grid parameterizations are used in your LSS? (none, one or several of the below)

a. Sub-grid runoff scheme

b. Sub-grid precipitation interception

c. Sub-grid saturated fraction for evaporation

d. Fractional snow cover area parameterization and how it influences the overall surface energy budget

11. What is the surface energy budget structure of your LSS?

a. Single soil/snow/vegetation composite surface energy budget

b. Distinct canopy and soil with composite snow

c. Distinct soil, canopy and snow

d. Other (describe)

Data issues:

  1. Which soil parameters are used in your LSS?
    1. Sand, silt, clay fractions directly (and what method for deriving hydraulic and thermal parameters?)
    2. Other derived parameters from Table 3 (which ones?)
    3. Provided Cosby parameters based on soil class (Table 2)
    4. Parameters derived from provided data (describe how and for what method; e.g., Van Genuchten)
    5. Other (describe)
  2. What vegetation type data are used by your LSS?
    1. IGBP land cover types (Table 5)
    2. SiB vegetation types (Table 5)
    3. BATS vegetation types (Table 5)
    4. Plant Functional Types derived from IGBP data
    5. Other (describe)
  3. Which of the supplied vegetation data sets from Table 4 did you use?
  4. Which forcing data from Table 6 did your LSS require?
  5. How did you interpolate the 3-hourly forcing data?
    1. Used the provided interpolation code from the GSWP web site
    2. No interpolation (model time step is 3 hours or longer)
    3. Other (describe)
  6. What data sets does your LSS require that were not supplied by GSWP? How did you supply these data?
