IR SAT Product
Infared
Available 24/7
Detects temperature difference associated with cloud height
WV
Water Vapor
Available 24/7
Displays the amount of water vapor in higher levels of the atmosphere
SAR
Computerized Search and Rescue
primary use for man overboard
Sub-refraction
EM waves bend more away from the Earth surface
standard refraction
Normal standard atmosphere EM waves travel in a strait line
Super-refraction
EM waves bend more toward the surface of Earth than under normal conditions
Doppler Effect
The change in frequency for an observer
Trapping
EM waves refracting SHARPLY downwards, the reflecting off Earth’s Surface
TAWS
Target Aquisition Weapons Software
EO sensors used for detection, surveillance, and in weapons systems
FLIR
Forward Looking Infrared
Most significant impact is thermal crossover. time of say may effect if the target and environment share the same temperature
OTSR
optimum Track Ship routing
Weather advisory service for safety and damage avoidance, sparring long range planning to en route surveillance
OSTR Weather Advisory
Issued when conditions are forecast to appoach or meet winds or seas limits as determined by a suppoerted unit
OSTR direct recommendations
Issued when conditions are forecast to secede wind or sees limits as determined by a supported unit
Special weather advisory
FWC Norfolk, used for prolonged periods of heavy weather in high traffic areas of AOR, 72hrs+ in advance
Sub-refraction layer
occurs when atmosphere conditions allow water vapor content to increase with height and the temp decrease
Mixed layer
The upper layer of the ocean consisting of relatively warmer temps + depths to a max of 450 meters or 1500 feet.
Super-refraction layer
Happens when warm dry air overlies cool moist air
