摘要：The Global Change Observation Mission-Climate (GCOM-C) satellite with its high resolution sensor, the Second generation Global Imager (SGLI), are expected to provide new insights in the study of smaller scale clouds than actually detected, as well as refined measurements of the impact of clouds in the climate. To examine long-term trends of climate variations, the observations from this satellite should be combined to analyses of the present state of the climate. Using data from the National Oceanic and Atmospheric Administration-Advanced Very-High-Resolution Radiometer (NOAA-AVHRR) satellites' series, the present study analyzes this climate state and its connectivity to future observations as those from the GCOM-C satellite. 25 years of cloud data are examined and variations in the cloud types distribution and amounts are discussed. To correct for the orbit drift (due to late equatorial time crossing) of the various NOAA satellites used in this study, the cloud properties estimated are adjusted, taking into account the relationship between the drift and the solar zenith angle. Results show that the corrections made give reliable long-term cloud amounts trends and allow for a reasonable transition to the GCOM-C satellite
