Additional POES information

I think the importance of the SARSAT payload should be emphasized, the POES spacecraft is one of a few satellite systems that accounted for over 41,000 rescues since the COSPAS-SARSAT program began in 1982. John.adler (talk) 08:44, 28 February 2017 (UTC)

Being knowledgeable of how POES works specifically through its instruments should be essential. The POES instruments include the Advanced Very High Resolution Radiometer (AVHRR) instrument and the Advanced TIROS Operational Vertical Sounder (ATOVS) suite. tannercho (talk) 08:14, 28 February 2017(UTC)

I agree that knowledge of the many instruments of POES, their use and functionality individually and collaboratively is important. Another key instrument of POES is the HIRS/4. This instrument has over 20 channels in which it senses through a filter wheel. The HIRS/4 data is closely examined alongside the Advanced Microwave Sounding Unit (AMSU) data to create atmospheric vertical profiles.

Another interesting instrument of POES includes the Space Environment Monitor-2 (SEM-2). This sensor takes measurements of radiation belts and fluctuations of charged particles at the altitude of the satellite. SEM-2 provides awareness of solar and terrestrial anomalies that may impair the operation of the satellite and its other sensors.

To expand on the subject of POES being used for the Search and Rescue communitity. COSPAS-SARSAT is the international humanitarian Search and Rescue Satellite-Aided Tracking System that has been alerting and locating information to search and rescue authorities for more than twenty years. COSPAS-SARSAT satellites detect 406 MHz distress signals at all times from nearly any place on the globe. Each 406 MHz beacon has a unique fifteen digit identification (ID) code embedded within its signal which allows rescuers to have an identification of the party in distress before they head out on the rescue. There is no charge for this service provided in conjunction with NOAA and SARSAT. Nibr0574 (talk 20:42, 1 March 2017 (UTC)

Expanding on POES instruments, The Solar Backscatter Ultraviolet Radiometer (SBUV/2) is a spectrally scanning radiometer with two modules. The sensor module and the electronics module form an instrument that can be used as a cloud cover radiometer (CCR) and a monochrometer. This detection helps to measure solar irradiance of the earth, or backscattered solar energy in the near UV spectrum. Atmospheric changes such as vertical ozone distribution and the influence of small changes to atmosphere composition. The physical properties of the intstrument can be discussed further.

AVHRR

The POES constellation is equipped with the Advanced Very High Resolution Radiometer (AVHRR). This multispectral system provides data in four or five bands, located in the visible, near-infrared, and thermal spectrums. The spacial resolution is 1.1 kilometers at nadir. AVHRR data are used for the study of terrestrial vegetation, snow cover, land-use monitoring, sea surface temperature (SST) and energy balance calculations. — Preceding unsigned comment added by Dillonragar (talk • contribs) 02:27, 19 March 2017 (UTC) Dillonragar (talk) 02:29, 19 March 2017 (UTC)
