AEROCOM and AEROSAT AAOD and SSA study – Part 1: Evaluation and intercomparison of satellite measurements
Global measurements of absorbing aerosol optical depth (AAOD) are scarce and mostly provided by the ground network AERONET (AErosol RObotic NETwork). In recent years, several satellite products of AAOD have been developed. This study's primary aim is to establish the usefulness of these dataset...

Global measurements of absorbing aerosol optical depth (AAOD) are scarce and mostly provided by the ground network AERONET (AErosol RObotic NETwork). In recent years, several satellite products of AAOD have been developed. This study's primary aim is to establish the usefulness of these datasets for AEROCOM (Aerosol Comparisons between Observations and Models) model evaluation with a focus on the years 2006, 2008 and 2010. The satellite products are super-observations consisting of <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1" display="inline" overflow="scroll" dspmath="mathml"><mrow><mn mathvariant="normal">1</mn><msup><mi/><mo>∘</mo></msup><mo>×</mo><mn mathvariant="normal">1</mn><msup><mi/><mo>∘</mo></msup><mo>×</mo><mn mathvariant="normal">30</mn></mrow></math> <svg:svg xmlns:svg="http://www.w3.org/2000/svg" width="57pt" height="11pt" class="svg-formula" dspmath="mathimg" md5hash="54d43dcfd45f49f6bd3e8b718d7a312d"><svg:image xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="acp-21-6895-2021-ie00001.svg" width="57pt" height="11pt" src="acp-21-6895-2021-ie00001.png"/></svg:svg> min aggregated retrievals.
