Gas attenuation correction attempts to compensate for overall (two-way)
beam losses due to absorption by atmospheric gasses. The correction is
linear with range, and is added to the data along with range normalization.
Therefore, clearing the RNV bit in Word #2 above disables the correction.
Of course, gas attenuation compensation can still be turned off even when
RNV is on, simply by setting a slope of 0.0 dB/km.
An attenuation of G db/km is encoded into the unsigned 16-bit word N as
follows:
0 ≤ N ≤ 10000 G = N / 100000
else G = 0.1 + (N - 10000)/10000
This format is backward compatible with the previous linear format for all
values between 0.0 and 0.1 dB/km; but it extends the upper range of values
from 0.65535 up to 5.6535. These larger attenuation corrections are needed
for very short wavelength radars.
