NASA's Active Cavity Radiometer Irradiance Monitor Satellite (ACRIMSAT) is a mission dedicated to monitoring the Sun's total solar irradiance (TSI) with exceptional precision. Launched in 1999, ACRIMSAT is a significant component of NASA's efforts to study and understand the Sun's influence on Earth's climate and energy balance.
ACRIMSAT is equipped with an instrument called the Active Cavity Radiometer (ACR), which accurately measures the Sun's energy output. The data collected by ACRIMSAT helps scientists study variations in solar irradiance, which play a crucial role in Earth's climate and weather patterns.
By providing accurate and continuous measurements of solar irradiance, ACRIMSAT contributes to climate research, weather forecasting, and solar energy studies. This mission exemplifies NASA's commitment to advancing our knowledge of the Sun-Earth connection and its impact on our planet's climate and environment.
