Why does raw top-of-atmosphere (TOA) radiance need correction before quantitative land-surface analysis?

ATOA radiance already equals true surface reflectanceBAtmospheric scattering and absorption distort the surface signal wavelength-dependently on both the down- and up-pathCSatellites cannot measure radiance at allDSurface reflectance has no wavelength dependence

Where Does Our Food Come From? Almost everything we eat starts on a farm. Farmers grow plants and raise animals so the rest of us have food to buy and cook. A Farmer's Year From Farm to Table Once a crop is harvested, it still has a journey

What is the single biggest structural difference between the phosphorus cycle and the nitrogen or carbon cycles?1 / 9

Phosphorus has no significant atmospheric phase — it doesn't exist as a gas in any biologically important form, so it can't move through the air the way N₂ or CO₂ does. It cycles almost entirely through rock, soil, and water.

What is the carbon cycle?1 / 6

The carbon cycle is the movement of carbon atoms through the atmosphere, oceans, land, and living things. Plants absorb CO₂ from the air; animals eat plants; when living things die or burn, carbon returns to the atmosphere.

What does CLORPT stand for, and what does it describe?1 / 9

CLORPT is the mnemonic for the five factors that control soil formation, first formalised by Hans Jenny (1941): Climate, Organisms, Relief (topography), Parent material, and Time. Any two soils that differ do so because at least one of these five factors differed during their development.
