CLARREO Pathfinder
Climate Absolute Radiance and Refractivity Observatory Pathfinder
Unparalleled accuracy to understand our changing climate
The Climate Absolute Radiance and Refractivity Observatory Pathfinder (CLARREO-PF) is an instrument payload that will measure reflected solar radiation at an unprecedented level of accuracy. CLARREO-PF data will do this by taking highly accurate measurements of sunlight reflected by Earth and the Moon. These measurements, anchored to international standards, will be five to ten times more accurate than those from existing sensors. The high accuracy in the measurements makes it possible to detect Earth’s subtle climate change trends decades sooner, and provides the knowledge needed to make informed decisions in response.
