Satellite calibration involves the process of adjusting and fine-tuning the measurements taken by satellites to ensure that they are accurate and reliable. This is essential for ensuring that the data collected by satellites is valid and can be used for a variety of scientific and practical purposes, such as weather forecasting, environmental monitoring, and disaster response. Calibration processes typically involve comparing satellite measurements to ground-based measurements or other reference data sources, making necessary adjustments, and validating the accuracy of the results. This ensures that satellite data is consistent, reliable, and can be used effectively for a wide range of applications.
