  "content": "<p>The sun is redder in the morning and at night and this should be reflected throughout regions all over the image in higher red to blue and green ratios. Length of shadow is also a good indicator of time of day. Blue light more intense as dust rises and reflects it back into space. Look for pools of water that nay be shrinking in size as the days progress. Trees may be getting more leaves and so intensity of green will increase. Look for places where air has large density differences and light is being mixed at the boundary\nby rising thermals which are usually significant by midday. More cars on roads early in morning and late afternoon rush hour. Fewer cars parked outside houses after breakfast and people have gone to work.\nMore large delivery vehicles by houses by mid morning. Look for clusters of cars by schools as parents collect children.</p>",
