The SKYNET is a ground-based radiation observation network dedicated to aerosol-cloud-solar radiation interaction researches (e.g., Takamura et al., 2004; Nakajima et al.,2007).
The primary objectives of SKYNET are:
In addition, the validation for satellite observations of Japan Aerospace Exploration Agency (JAXA), European Space Agency (ESA) and National Aeronautics and Space Administration (NASA) mission 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.
The SKYNET is organized in seven regional sub-networks, whose representatives are part of the International SKYNET committee that is the decision-making body of the network. The current committee members are listed in Table 1.
Each sub-network contributes for operating and maintaining the associated instrumentation. Some sub-networks have Regional SKYNET Data Center (RSDC) to accumulate data measured in the sub-network. Each SKYNET participant belongs to one of the seven sub-networks.
The raw data are transferred from each RSDC to the International SKYNET Data Center (ISDC). The ISDC produces standard products on aerosol optical properties using the standard algorithms approved by the International committee and provides products via web.
Each RSDC produces new research products, using also algorithms regionally developed. The European SKYNET radiometers network (ESR) is one of the RSDC, leaded by Institute of Atmospheric Sciences and Climate (ISAC) of the Italian National Research Council (CNR) and by the University of Valencia. ESR has a regional data center located in Italy and in Spain and dedicated web page.
Currently, there are two working groups (WGs);
Figure 1 shows the organization of SKYNET explained above.
