From 4 to 11 August 2026, one hundred Calitoo sun photometers<\/a> were calibrated at the Iza\u00f1a Atmospheric Research Center \u2013 Emilio Cuevas (IARC\u2013Emilio Cuevas<\/a>), operated by the Spanish State Meteorological Agency (AEMET)<\/a>, as part of the World Meteorological Organization Measurement Lead Centre (WMO-MLC)<\/a> programme for Aerosols and Water Vapour Remote Sensing Instruments.<\/p>\n

Calitoo sun photometers are used within the Global Learning and Observations to Benefit the Environment (GLOBE)<\/a> programme, a worldwide hands-on science and education initiative that involves primary and secondary schools in environmental observations.<\/p>\n

After manufacture, sun photometers need to be periodically calibrated to ensure the quality and reliability of their measurements of aerosol optical depth (AOD), an important parameter for characterizing atmospheric aerosols.<\/p>\n

The excellent calibration conditions at the IARC-Emilio Cuevas have once again provided an ideal environment for this activity. This is the fifth calibration campaign of Calitoo sun photometers carried out at Iza\u00f1a, following previous campaigns in 2014, 2015, 2017 and 2024.<\/p>\n

The calibration of these instruments at Iza\u00f1a contributes to improving the quality and consistency of aerosol observations collected by schools participating in the GLOBE programme worldwide.<\/p>\n
