15.6.2 Sequential Steps of the Exercise Implementation
The computer program “SEEREFL.exe” realizes the above algorithm and
calculates desired values. The dialogue on the screen is allowed.
The first question is:
Input filename for results:
It is necessary to input the file name for results output. The file is rewritten when
the program is rerun and is open till the program terminates. Then two stages are
accomplished.
The first stage is studying dependences of the spectral brightness coefficient and
albedo on solar zenith angle. The consequent questions are output on the screen
Input wind speed (m/s):
It is recommended to input two-three values: the weak wind 2.0, moderate wind
7.5, and strong wind 15.0. Values are real numbers and are input with decimal
point.
Attention! Several values divided by space in one line. For proposed example:
2.0 _7.5_15.0 “Enter”
Input wind azimuth (grad):
It is recommended to input one-two values of the azimuth: 0.0 и 90.0. The
azimuth is reckoned from the Sun direction.
The program calculates desired values as functions of solar zenith angle for all
set of input parameters at the definite network of viewing directions. The viewing
direction is characterized with nadir angle and azimuth from the Sun direction.
Result is formatted as a two-dimensional table (zenith angle and SBC) sequent
output for all viewing directions and as three-dimensional tables (zenith angle,
azimuth, and SBC) for all solar zenith angles. The latter provides two-dimensional
plots as isometric lines.
The second stage is the study of the SBC and albedo dependence on the wind
velocity.
The consequent questions are output on the screen
Input sun zenith angles (grad):
It is recommended two-three values of the solar zenith angle (in degrees)
corresponding to high solar position 45.0, mean value 65.0, and low Sun 80.0.
Input wind azimuth (grad):
Answer is considered above.
The program calculates desired values as function of the wind velocity for all
sets of input parameters and output to result file.
The program is terminated.
Finally you need to:
– Plot obtained dependences (diagrams present the result in case of distribution
over interaction ratio).
– Describe (and physically interpret if possible) obtained dependences.
