Clouds cover about 70% of the Earth's surface and profoundly affect the global environment and climate change. Till now, the accurate observation and characterization of cloud macroscopic and microphysical properties are still challenging. Due to the inhomogeneity of clouds and their relation with various weather systems, there are still uncertainties in the cloud products which are derived from satellites.

 The initiation of CARE is to echo the need to promoting the understanding of clouds and their impact on Earth's radiation budget. The CARE is short for the Cloud remote sensing, Atmosphere radiation and Renewal Energy. In 2018, Dr. Husi Letu convened the 1st International symposium on the Cloud Remote Sensing, Atmospheric Radiation and Renewal Energy Application (CARE 2018), which focused on promoting international collaborations as well as in-depth exchanges of ideas and experiences on cloud remote sensing, particularly the advances in fields of atmospheric radiation, solar energy applications and featuring global monitoring. In 2020, the algorithm team initiated the satellite products plan in the name of CARE 1.0, which was developed to serve the research of global energy budget and interaction between cloud-radiation-climate changes.

 Version 1.1 of CARE products has been partly released since July 2022. The CARE datasets contained cloud, aerosol, precipitation, water vapor and radiation products. There is still a long way to go for CARE and the continuous improvement of cloud remote sensing datasets in terms of spatial consistency, precision, and availability.
