Satellites (POES) starting with TIROS-N in 1978. Onboard the TIROS-N,
NOAA-6, 8 and 10 POES Satellites, the AVHRR Sensor measures in
four spectral bands, while on the NOAA-7, 9, 11, 12 and 14 POES
Satellites, the sensor measures in five bands. The AVHRR/3 sensor
on NOAA-15 and 16 measures in six bands though only five are transmitted
to the ground at any time.

AVHRR Pathfinder - The
current AVHRRPF (or PATMOS) data sets cover the following satellites
and time periods: NOAA-7 (9/81 - 1/85), NOAA-9 (2/85 - 10/88),
NOAA-11 (11/88 - 8/94), and NOAA 14 (3/96 - 12/00). PATMOS-A1
computes statistics of the radiances in all five channels of the
AVHRR from clear and cloudy 2x2 pixel arrays and the total cloud
amount for a total of 71 parameters. PATMOS-A2 computes statistics
of aerosol optical thickness over the oceans, and shortwave absorbed
radiation and outgoing longwave radiation parameters of the radiation
budget at the top of the atmosphere. Data presented here are extracted
from the PATMOS-A2 monthly mean.
