Example text

In the case of the other two variables (surface and air temperatures), major differences arise in Australia. This may be due to different specifications of emissivity/surface vegetation for desert/arid climates. Nonetheless, the variables have a good degree of agreement with each other. The surface temperature estimates from the two sensors showed agreement for both the average seasonal cycle and the spatial standard deviation over the continental regions. The air temperature estimates of the two sensors do not agree as well.

2 Surface temperature comparisons with TOVS The model simulated surface temperatures were compared with TOVS surface temperature data (Lakshmi and Susskind, 2001) for the basin for a period of 20 years (1980–99) for both the morning and afternoon overpasses of the satellite. The time of observation for each pixel is different depending on the latitude and distance from nadir. The exact time of each observation is included in the data. The VIC-3L model simulated surface temperature for the individual pixels were matched with the exact time of TOVS observations.

The work of Maurer et al. 8% with comparisons carried out for a 10-year period. 5%, respectively for RMSE and bias over a 50-year period. The actual differences could be attributed in part to the period of comparison (10 years versus 50 years) chosen. Sensitivity studies of spatial resolution on streamflow simulations were carried out by Haddeland et al. (2002), indicated a greater degree of dependence. Suggestions have been made for the use of diurnal cycles of streamflow in understanding the various hydrological components, namely, snowmelt, evapotranspiration, and infiltration.
