🗑
|
||||
| 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
🗑

🗑
|
||||
| -Has a lower emissivity than choppy water | Calm water
🗑
|
||||
| ______ water emits less radiaion while______ water emits more radiation | Calm, Choppy
🗑

| 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
