Atmospheric carbon dioxide (CO2) is the most important anthropogenic greenhouse gasis considered to be the primary cause of global warming. A lack of knowledge regarding global CO2 emissions has introduced significant uncertainties into studies of climate change. A state-of-the-art space-borne hyperspectral instrument provides will provide an opportunity to achieve accurate CO2 measurement with global coverage to improve estimations of the global carbon budgetinvestigate climate change

An unmanned aviation vehicle(UAV) glided into the uninhabited central Taklamakan during a field observation campaign on18-24 July, 2017. Its the first time the lower atmosphereland surface in Taklamakan are observed by a UAV. The UAV was developed by the Institute of Atmospheric Physics (IAP), CASthe campaign was conducted by IAP, in collaboration with the Institute of Desert Meteorology, China Meteorological Administration

More than 90% of the earth’s energy imbalance (EEI) in the climate system is sequestered in the oceanconsequently the ocean heat content (OHC) is increasing. Therefore, OHC is one of the most important indicators of global warming. During the past 30 years, many independent groups worked to estimate historical OHC changes. However, large uncertainty has been found among the published global OHC time series. For example, during the current surge of research on the so-called “hiatus” or “slowdown”, different scientific studies draw quite different conclusions on the key scientific question such as “Where is the heat redistributed in the ocean?” This motivates us to give a detailed analysis about globalbasin OHC changes based on multiple ocean datasets

Aerosol is currently a hot topic both in scientific community. Scientists know it as a particulate matter, cloud condensation nuclei (CCN) or ice nuclei (IN) while aerosol is known to general public as PM2.5/10 as environmental pollution has become an increasing concern. Stratospheric aerosol, however, very far away from the Earth surface, receives too much less attention, partly because its formation is closely related to the natural sources (such as volcanic plumeoceanic dimethyl sulfide)
