This instrument has been developed under the scientific and technical supervision of Dr. Phillipe Goloub and Eng. Luc Blarel from LOA (CNRS-University of Lille). Calitoo sun-photometers are used in the Global Learning and Observations to Benefit the Environment (GLOBE) program, which is a worldwide hands-on, primary and secondary school-based science and education program.<\/p>\n<p style=\"text-align: justify;\">After manufacturing, the sun-photometers must be periodically calibrated to provide AOD measurements. In the periods 26 June \u2013 3 July 2017 and 18-27 June 2018, a total of 200 Calitoo sun-photometers were calibrated using the Langley method at IZO. Furthermore, the new developments performed in the Calitoo were also tested at Iza\u00f1a: new software capabilities, a real-time Angstrom Exponent computation and analysis, as well as the Calibot (CALItoo \u2013 roBOT) system for automatic sun tracking (still in testing phase).<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter  wp-image-957\" src=\"http:\/\/desarrollo-vm.ciai.inm.es\/testbed\/wp-content\/uploads\/2023\/06\/Figure32.png\" alt=\"\" width=\"579\" height=\"593\" srcset=\"https:\/\/testbed.aemet.es\/wp-content\/uploads\/2023\/06\/Figure32.png 744w, https:\/\/testbed.aemet.es\/wp-content\/uploads\/2023\/06\/Figure32-293x300.png 293w\" sizes=\"auto, (max-width: 579px) 100vw, 579px\" \/><\/p>\n<p style=\"text-align: justify;\"><strong>Figure 1.- <\/strong>Top left and right, Calitoo sun photometer calibration campaigns in 2017 and 2018 at Iza\u00f1a Atmospheric Observatory.
