Constant sampling within the diurnal cycle (minimizing the effects of orbital decay and orbit drift) should be maintained; A suitable period of overlap for new and old satellite systems should be ensured for a period adequate to determine inter-satellite biases and maintain the homogeneity and consistency of time-series observations; Continuity of satellite measurements (i.e. elimination of gaps in the long-term record) through appropriate launch and orbital strategies should be ensured; Rigorous pre-launch instrument characterization and calibration, including radiance confirmation against an international radiance scale provided by a national metrology institute, should be ensured; On-board calibration adequate for climate system observations should be ensured and associated instrument characteristics monitored; Operational production of priority climate products should be sustained and peer-reviewed new products should be introduced as appropriate; Data systems needed to facilitate user access to climate products, metadata and raw data, including key data for delayed-mode analysis, should be established and maintained; Use of functioning baseline instruments that meet the calibration and stability requirements stated above should be maintained for as long as possible, even when these exist on decommissioned satellites; Complementary in situ baseline observations for satellite measurements should be maintained through appropriate activities and cooperation; Random errors and time-dependent biases in satellite observations and derived products should be identified.
