Remote Sensing C

[Alex-RCHS]

For those of you who competed in Remote Sensing at Princeton yesterday, I have finished digitizing all of the test and survey data. Since you guys made it possible for me to have this data, I feel it is only fair you all have access to it as well. Here the link! https://drive.google.com/open?id=1frIOz ... cEvR9ZYOm1

I didn’t compete, but it’s cool that you did that.

I love the confidence of some of those teams — 2%, 10%, pi%

I'm not sure when to use the Stefan Boltzmann equation, Wien's Displacement Law, and the Planck equation. Can anyone elaborate what each equation is used for and how to use it?

I'm not sure when to use the Stefan Boltzmann equation, Wien's Displacement Law, and the Planck equation. Can anyone elaborate what each equation is used for and how to use it?

Stefan-Boltzmann Equation: This equation gives the amount of energy radiated each second per unit area at a given temperature. Therefore, if the question gives you temperature and you are asked to look for power or luminosity, you know you are dealing with energy and you can go ahead and use this formula. Questions that require the use of this law can be pretty diverse, but most of the time they deal with planetary equilibrium temperature (which isn't too bad if you practice a bit). Key Words: temperature, power, luminosity, emissivity, area, planetary equilibrium.

Wien's Law: This is possibly the most basic of the three. For a given temperature, Wien's Law gives the peak wavelength at which radiation is emitted from a blackbody. Therefore if you are given temperature and asked to find wavelength (or vice versa) then you know you have to use this law. Questions that test this tend to be pretty straightforward and easy to identify. Key Words: temperature, wavelength.

Planck Function: You'll almost never have to calculate anything with the Planck function; you'll mainly have to answer basic conceptual questions about it. For example, if you integrate the Planck Function over all wavelengths then you get the Stefan-Boltzmann equation. Personally, I would just try to have a good conceptual understanding of this. Key Words: spectral density, EM radiation, blackbody.

I am doing an almost complete overhaul on my old notes/cheat sheet I used for Regionals because they were pretty unhelpful. Can anyone suggest any tips when creating/organizing my cheat sheet when I do the test? If this helps, one issue I encountered was that I already knew or memorized almost all of the stuff on my 4-page cheat sheet, so I didn't really "need" to use my cheat sheet that much at all.

I think our note sheet is mostly for statistics and other stuff which it would just be pointless to memorize - nobody needs to remember the GWP of every possible gas yet those questions come up, so you can put it on your note sheet; nobody needs to remember the wavelength of every atmospheric window yet those questions come up, so you can put it on your note sheet, and so on.

Do you have to have the refractive indices on your note sheet or do they usually give you the refractive index?

Refractive indices normally don't come up on remsen tests...

What is nominal scale?

Sorry to jump in, but I was wondering if there was any set database of remote sensing terms and general concepts to understand. As a kinda noob to this event (I've done it before but I don't understand any of it ), I've been hard-pressed to find a good reliable source of stuff to learn. It sort of seems like everything is just being thrown at me randomly and when I finally get one concept there's like 3-4 more that are somewhat related but also totally different and confusing! For example, I have notes on most of the satellites but I just found out about different bands today . Any ideas/help/tips?

I haven't experienced this as much this year, but last year, practically every test would start with a vocab matching section, and just going through the answer keys of those was how I learnt a lot of the vocabulary.
