<p>Sparv Embedded, Sweden (<span class="uri">http://windsond.com</span>, last access: 22 February 2019), has answered the call for less expensive but accurate reusable radiosondes by producing a reusable sonde primarily intended for boundary-layer observations collection: the Windsond S1H2. To evaluate the performance of the S1H2, in-flight comparisons between the Vaisala RS41-SG and Windsond S1H2 were performed during the Dynamics–Aerosol–Chemistry–Cloud Interactions in West Africa (DACCIWA) project (FP7/2007–2013) ground campaign at the Kumasi Agromet supersite (6<span class="inline-formula"><sup>∘</sup></span>40<span class="inline-formula"><sup>′</sup></span>45.76<span class="inline-formula"><sup>′′</sup></span> N, 1<span class="inline-formula"><sup>∘</sup></span>33<span class="inline-formula"><sup>′</sup></span>36.50<span class="inline-formula"><sup>′′</sup></span> W) inside the Kwame Nkrumah University of Science and Technology (KNUST), Ghana, campus. The results suggest a good correlation between the RS41-SG and S1H2 data, the main difference lying in the GPS signal processing and the humidity response time at cloud top. Reproducibility tests show that there is no major performance degradation arising from S1H2 sonde reuse.</p>
