Processes which control the Earth’s Temperature
Oupický, Pavel
There are discussed in this paper some of natural processes which control the temperature of Earth and they are explained and confronted with climate models Daisyworld, Greenhouseworld and Moses. There are presented also the results from the measuring of plant reflectivity with spectroradiometer

Šolc birefringent polarizing filter for more spectral lines Šolc birefringent polarizing narrow - bandpass filters are successfully used for professional observations of solar chromosphere. They are usually constructed to work for only one transmitting wavelength. Principally it is possible to design such filters to transmit more narrow – banded spectral lines. Filter consist of two parts: Frontal part is broad – band filter, with which, required spectral line can be adjusted. Second – main part consists of 26 quartz plates. Filter is designed for observation of Sun in interesting spectral lines: KII, HY, BaII, HZ, D1, D3 and He.
