Am I correct with my answeres below?

During which hours of the day is the earth's emitted radiation highest and Why?

My Answer: I think it is in the afternoon because of the increase in surface temperature.

Why are values of LW^ higher in the summer than in the winter?

My Answer: Is it because of the surface temperature.

What makes the difference in surface albedo between 11:00 am and 5:00 pm?

• Science -

I have no idea what LW^ means. Surface temperature is higher in summer because the days are longer and the sun in higher in the sky.

Ground surface albedo should not change much from 11 AM to 5PM; however many clouds disappear or become thinner during this interval, making the albedo of the earth (as seen from space) lower
