7. WEATHER RADARS ACCORDING TO FREQUENCY BANDS
L BAND RADARS
15 – 30 cm and 1 – 2 GHz
Clear air turbulance (CAT)
S BAND RADARS
8 – 15 cm and 2 – 4 GHz
Near and far weather observation
C BAND RADARS
4 – 8 cm and 4 – 8 GHz
Short range weather observation
X BAND RADARS
2.5 – 4 cm and 8 – 12 GHz;
Short range weather observation and cloud development
K BAND RADARS
0.75 – 1.2 cm or 1.7 – 2.5 cm and 27 – 40 GHz or 12 – 18 GHz
It is similar to the X band, but is just more sensitive
