Remote Sensing C

Postby whythelongface » September 6th, 2017, 5:38 pm

Welcome to the 2018 Remote Sensing Question Marathon!
Short event description: Participants will use remote sensing imagery, data, and computational process skills to complete tasks related to climate change processes in the Earth system.

Please remember to use the spoilers to mask your answer. That way, other people can participate in the marathon as well!

I'll start with an easy one: Give two examples each of carbon sources and sinks.

Congratulations to WW-P South for winning 14th place at Nationals!

Answer
2 carbon sources are factories and car emissions, and 2 carbon sinks are the ocean and fossil fuels such as coal.

Another simple one:

How do clouds effect the amount of sunlight to reach earth's surface. Then identify and define the related term.

Answer
Clouds reflect/absorb incoming solar radiation, largely caused by high albedo, the percentage of light reflected. This reduces the amount of light that reaches the surface.

Why is it so hard to identify the source material of an aerosol in most air samples?

Answer
Aerosols undergo numerous physical and chemical changes over time, affecting their size, composition, and structure. This can make it difficult to identify the original source.

Answer
Rayleigh scattering is generally caused by smaller particles in the atmosphere (eg atmospheric gases) while Mie scattering is caused by somewhat larger particles such as dust. Also, Rayleigh scattering happens high in the atmosphere while Mie scattering happens lower in the atmosphere, and Rayleigh scattering happens to wavelengths of light significantly larger than the scattering particles while Mie scattering happens to wavelengths of light around the same size as the scattering particles.

Q: What is the benefit from having the A-train satellites follow the same path to one another in quick succession?

Answer
Allowing the A-train satellites to follow the same path in quick succession allows the satellites to gather data and images almost simultaneously. This lets us analyze all factors at one given time so we can make connections instead of the data being given at sporadic time intervals, which isn't much use alone (happens if the satellites were in different paths or weren't taken very close to the same time).
