Objectives
• To improve the use of space-based global observations for weather, climate and environmental applications through operational inter-calibration of satellite sensors.
• To provide for the ability to re-calibrate archived satellite data using the GSICS intercalibration system to enable the creation of stable long-term climate data sets
• To ensure that instruments meet specification, pre-launch tests are traceable to SI standards, and the on-orbit satellite instrument observations are well calibrated by means of careful analysis of instrument performance, satellite intercalibration, and validation with reference sites
Next Steps: Global Space-based Inter-Calibration System (GSICS)
