“…As single-site measurements are suitable only for small basins, furthermore tending to underestimate on-lake wind stress if done on land (Valerio et al, 2017), and as networks of in-lake wind stations to build spatially interpolated fields have been successfully operated up to now only for limited time inside research projects, as done for few years on Lake Como (Morillo et al, 2009;Laborde et al, 2010Laborde et al, , 2012Copetti et al, 2020) and Lake Iseo (Vilhena et al, 2013;Valerio et al, 2017), the most solid solution to solve wind inhomogeneities are atmospheric models. Works on Swiss lakes have employed the hourly reanalysis data from the MeteoSwiss atmospheric model COSMO (Consortium for Small-Scale Modeling -www.cosmo-model.org), both through its older version COSMO-2 (Bonvin et al, 2013;Razmi et al, 2013Razmi et al, , 2014Råman Vinnå et al, 2017, 2020Soulignac et al, 2018;Dissanayake et al, 2019;Nouchi et al, 2019;Baracchini et al, 2020;Caramatti et al, 2020) and through the new one COSMO-1 (Baracchini et al, 2020;Caramatti et al, 2020). While COSMO-2 has 2.2 km resolution and data can be retrieved since 2008, COSMO-1 has 1.1 km resolution, data being available from 2016 onwards.…”
