Question	Answer
This satellite product does not display clouds but displays derived weather features.Ex: Surface Wind Speeds and Rain Rates	Microwave Imagery
What are four advantages of Microwave Imagery?	-Accuracy-Long Wavelength-Surface Monitoring-Data Sparse Coverage
Very accurate with data such as wind speeds over water, being verified by bouys and ships.	Microwave Imagery
Uses long wave lengths to enable the satellite to penetrate clouds and see the surface below.	Microwave Imagery
Has the ability to minimize attenuation, as well as ensuring consistent signal propagation.	Microwave Imagery
Ideal for monitoring the earths surface.	Microwave imagery
Diurnal(day,night insolation) has no effect on this type of imagery.	Microwave imagery
While other imagery can be affected by sun angle, this has no impact on this imagery.	Microwave Imagery
Has the ability to cover data sparse areas.	Microwave Imagery
Circulation center, cyclones and anticyclones, as well as low level convergence zones are easily distinguished.	Microwave Imagery
An invaluable tool in the mid-latitudes and tropics.	Microwave Imagery
Three sensors of the Product Creation Process	-Detection Process-Processing-Shared Processing Program (SPP)
Microwave radiation is recieved by satellite sensors that detects radiation emitted and reflected by earth and its atmosphere.	Detection Process
Once the data is recieved by the satellite it transmits the data to computer systems on the ground.Once downloaded applies a series of algorithms to create weather products.	Processing
Program through which products created are available, managed by (NESDIS).	Shared Processing Program (SPP)
The Shared Processing Program (SPP) is managed by what information service?	National Environmental Satellite, Data and information service (NESDIS)
The (SPP) programs are derived by what three governmental agencies?	-Air Force Weather Agency (AFWA)-the Navy's Fleet Numerical Meteorological and Oceanography Center (FNMOC) -the National Oceanic and Atmospheric Administration (NOAA)
What are the three Microwave Emission factors/ unique microwave radiance "signatures" or Variables in radiance.	-Emmisitivity-Spatial uniformity-Polorization
Earth and the atmosphere constantly emit...	Microwave Radiation
Emissivities are low and variations are significant.	Microwave Emissivities
Emissivities are high and variations are minor.	Infrared Wavelengths
-Is a constant emmiter with little or no diurnal(day,night) changes -Has a low emissivity-Produces long Microwaves	Water
A feature's emissivity may also vary with its ...	Physical State
-Has a lower emissivity than choppy water	Calm water
______ water emits less radiaion while______ water emits more radiation	Calm, Choppy
Clouds have a varying emissivity based on the ______ ________ in the ____ ________	Moisture Content, Air Parcels
______ air emits less radiation while______ air emits more radiation	Moist, Dry
Clouds have a ______ emissivity which in turn produces______ microwaves	High, Short
When viewing ________ wavelengths low and middle clouds appear slightly ______ than sea water	Infrared, Colder
When viewing_________ frequencies low and middle clouds appear slightly ______ than sea water but are actually _______ because of higher emissivities	Microwave, Warmer, Colder
While water and clouds have a certain degree of variance _______ is the most variable emitter	Land
The great variance in land is due to the moisture content in soil. ______ soil emits less radiation while _____ soi emits more.	Wet, Dry
The emissivity varies greatly because ______ produces both long and short microwaves	Land
Emissivity variances can result in data ______ or data_______	Thresholding, Rejection
An averaging of the data	Data Thresholding
Discarding of Data	Data Rejection
