8.4.2 Software and Set of Input Parameters
1. Computer programs “V_VARTS.exe” and “VARTS.exe” for the first part of the
practice, “V_TSRND.exe” and “TSRND.exe” for the second part.
2. The set of variants of initial parameters (the Table 8.1).
8.4.3 Test Questions
1. What initial parameters exactness does regulate the exactness of remote retrieving of the surface temperature?
2. What assumptions have been made for deriving the relation used for the calculation of the value T s ?
3. What initial parameter exactness does affect most dramatically on the exactness
of remote retrieving the surface temperature?
4. Do uncertainties DT s with the same value of the initial parameters uncertainties
differ for different approaches? Why do they differ?
5. What defines the exactness of estimating statistical characteristics of the surface
temperature T s with the Monte-Carlo method?
8.4.4 Sequential Steps of the Exercise Implementation
1. To study the theory with using additional books, pointed in references list.
2. To choose a variant with a set of the initial parameters from the Table 8.1.
3. To create input data files with the program “V_VARTS.exe”. Attention! The
procedure is to be executed twice for two wave numbers. After completing the
first data file “vvarts.dat” the calculation with the program “VARTS.exe” might be
done. Then to repeat operation with program “V_VARTS.exe” and “VARTS.exe”
for second wave number. The resulting output file “varts.dat” is written with the
same name (in the second completing the output file is rewritten).
4. To prepare the plan of accomplishing numerical experiments with program
“VARTS.exe” for
