2. NOAA-15,-16, -17, -18 NEDN
sample check
As of June 22, 2005
- Slow
but steady decrease in NOAA-18/HIRS noise. NEDN for some longwave
channels begin to meet the specification. NEDN for a sample orbit on June
22, 2005. (Note: channel 1 spaceview is often out of range.)

or in text
- Note: HIRS/NOAA-18 CH1 Spaceview is out of range. Its
NEDN is
misleading.
