And can someone define blackbody for me? I got it as "a physical body that absorbs all EM radiation regardless of frequency or angle of incidence."
A blackbody can be any object that absorbs any amount of EM radiation. Your definition is of a perfect blackbody (such as a black hole).

Alright, if people don't mind I'll move on to the next question.

What does a sun synchronous (SS) orbit mean? The A-Train satellites work together in this type of orbit, according to the wiki.
End of freshman season. Good luck to everyone! No state for us, but nevertheless great season. Regional was out of 12 teams. (CLC)

Mat Sci-> Second at regionals
RSensing -> First at regionals
Towers-> Third at regionals.

I think it's when they pass the same point on the earth at the same time every day. A-Train crosses the equator at like 1pm or something so it's called the Afternoon Train or something like that.

Also low key I think we're doing the question marathon thing wrong lol.

I think the way it's supposed to work is one person asks a question, and then someone else answers. The person that answered then asks another question. Here, I'll start us off. How do RAR and SAR work,and what are their uses and advantages over the other?
I was in a bin

Yeahhh lol.
Real aperture radar - uses a real antenna to receive backscattering from the radio wave it emits; requires absurdly long antennae for finer resolutions
Synthetic aperture radar - uses the movement of the RS platform to mimic longer antenna lengths; allows for finer resolution imaging without having to build really long antennae

Not sure what the advantages of RAR over SAR are.. :cry:

Sorry guys for not following the ways of the forum haha. I'm a bit new if you cannot tell.

Can you ask the next question Private Wang?

Ah yeah. woops. lil' late

1. Which instrument collected the data for this image and what satellite is it on?
2. What does the name of the instrument stand for?
3. What do the higher shortwave flux areas of the top image most likely give the position of?
4. How do the two images relate to each other and the earth's energy budget?

1. It is CERES? And if it is, it should be on Terra and Aqua satellites.
2. The instrument stands for Clouds and the Earth's Radiant Energy System.
3. Maybe the warmer parts of the earth, or global warming indicators?
4. They relate because they both show the different temperatures of the earth, and I guess the places that emit too much energy flux need to cut down on their use of greenhouse gases and such.

Am I kinda right? I won't post next question in case I'm wrong.

1. Yup
2. Good
3. It's mostly areas with cloud cover 
4. The areas covered with clouds (observed in the first image) have lower outgoing (longwave) radiant flux (second image), keeping more energy in the atmosphere.
