4. Accomplish the remote measurements of the surface temperature field and create
the corresponding data file using obtained surface emissivity.
5. Complete the complex processing data of remote measurement of the surface
temperature:
– calculate coefficients of 2-power approximating polynomial from remote
measurement of the surface temperature field;
– Perform the approximation of observational data to regular network;
– Present the final result in both digital and pseudo color forms;
– Plot isometric lines of the surface temperature.
6. Coincide direct and remote measurements of the surface temperature.
7. Analyze the water surface pollution impact on remote measurement of the
surface temperature and estimate the possibility of the remote indicating polluted areas.
7.6.2 Software and Set of Input Parameters
The automated one-channel IR-radiometer, mated with the computer.
1. Thermometers for contact temperature measurements.
2. Dish with water or other type of surface (sand, soil).
3. Computer programs for the surface temperature processing (“POLETS.exe”
and “TXT2ISO.exe”), as well as graphical packages SURFER or EXCEL
editors.
7.6.3 Sequential Steps of the Exercise Implementation
1. The sand emissivity e n is defined on the basis of remote and contact measurement
of the surface temperature with the computer program “RAD.exe” in option
« Definition of sand epsilon ».
It needs the following operations:
– To choose the item « Definition of sand epsilon » with buttons “"” and “#”
after running the program “RAD.exe”;
– To input the surface temperature value (measured with contact thermometer
during 3 min);
– To remember the obtained emissivity value e sand .
2. To accomplish remote measurement of the surface temperature field T s (x, y) and
to process obtained data complexly:
– To turn on the electric heater (at one corner of the dish) during 3–5 min for
creating the temperature heterogeneity of the surface in dish;
