1. (  Calculate the apparent radiant temperatures of the ocean at 276 K, assuming an ocean emissivity of 0.97. Show your work. 

2. (15 pts.) The atmospheric (sky) radiant temperature is 280 K with an emissivity of 0.83. Assume the same ocean temperature and emissivity as in question 3.  Compute the apparent/radiant temperature of the combined ocean and reflected sky. Think carefully about how to combine the sky and water temperatures.
