Directional polarization camera to help monitor carbon in terrestrial ecosystem

(ORDO NEWS) — The terrestrial carbon monitoring satellite was launched from the Taiyuan Space Center using the Long March 4B launch vehicle and entered the planned orbit.

It was equipped with a DPC (Directional Polarization Camera) camera developed by a research team from the Chinese Academy of Sciences.

DPC is designed to obtain data on multi-angle and multi-spectral polarization radiation of the Earth’s atmosphere and remote sensing of optical and physical parameters of atmospheric aerosols and clouds.

It will help in studies of global climate change, high-precision atmospheric correction of optical loads on a satellite platform, and in observations of atmospheric parameters.

This optimized camera has many advantages over the old model. Parameters such as spatial resolution and the number of viewing angles have been improved, and a new function “assessment of clouds in orbit” has been added.

The improved spatial resolution of aerosol remote sensing products enhances the possibilities of air pollution monitoring.

The “clouds in orbit” feature can be used to offload other optical satellites on the same satellite platform, thus increasing their lifetime in orbit.

The satellite will monitor the spread of atmospheric aerosols and improve the quantitative level of remote sensing of the earth in China. It will also provide operational support and research services in areas such as environmental protection, geodesy and mapping, meteorology, agriculture and disaster reduction.
