About SKYNET

SKYNET is an observation network dedicated to aerosol-cloud-radiation interaction researches (e.g., Takamura et al., 2004; Nakajima et al., 2007). The primary objectives of SKYNET are:

  1. to quantitatively evaluate long-term variations of aerosols and clouds properties, and therefore of the atmospheric radiation reaching the surface;
  2. SKYNET image (map and graph)
  3. to understand their effects on climate because of aerosol-cloud-radiation interaction.

In addition, the validation for satellite observations (e.g., GOSAT, GOSAT-2, GCOM-C, EarthCARE, Himawari-8, and GEMS) as well as climate model simulations and data assimilations are also within the scope of the SKYNET activity.

To accomplish these objectives, SKYNET observes optical and microphysical properties of aerosols and clouds and measures atmospheric radiation founded on a close international collaboration among national agencies, institutes, and universities.
