Short summary
The knowledge of the solar spectrum at the top of Earth's atmosphere is of great importance for climatic studies. Satellite instruments allow direct measurements; however, their calibration presents issues. It is possible to determine this spectrum precisely from Earth-based measurements as well, using the Langley plot technique and accurate calibration techniques. We present an infrared spectrum using these techniques for measurements made at the reference Mauna Loa Observatory.
