The figure also shows that for many days in winter, between May and September, the BT in the FIR is very low owing to the high transparency of the atmospheric windows. The high number of transparency windows from 230 to 1,200 [cm.sup.-1] (43.5-8.3 [micro]m pm) allows not only improvement of the characterization of the rotational water vapor band (Liuzzi et al.
It is important to stay within the area of atmospheric windows. Only in these windows is the atmosphere's transmissivity high enough for infrared radiation.
