* Who has developed this tool? CÆLIS has been fully developed by the Group of Atmospheric Optics, Valladolid University (GOA-UVa). This group is devoted to the investigation of atmospheric components (aerosol particles, water vapour, ozone, etc.) with optical in situ and remote sensing techniques.

In this web page you can find information and data from several scientific projects carried out by GOA-UVa:

RIMA-AERONET: management of the RIMA calibration facility, federated to AERONET.

AEROPA: project devoted to the investigation of aerosol properties over Europe.
