Final answer:
The statement that the CERES program studies the reflection and emission of radiation by clouds is true. This program is essential for measuring Earth's energy budget and understanding climate dynamics.
Step-by-step explanation:
The CERES program, which stands for Clouds and the Earth's Radiant Energy System, focuses on the study of the reflection and emission of radiation by clouds, so the statement is true. This program uses satellites equipped with sensors to collect data on the Earth's energy budget, which is critical for understanding climate change and weather patterns.
CERES instruments measure Earth's radiation budget and cloud properties; reflecting sunlight (albedo) and thermal infrared radiation that Earth emits. The sensors on these satellites must be cooled to record the low levels of radiation emitted from cold dark space with high accuracy. Cloudy nights are typically warmer than clear ones due to clouds' ability to absorb and re-radiate heat back toward the Earth's surface, essentially acting as an insulating layer.
