This one can carry a lot more sensors, so we have more temperature and humidity measurements, some gas sensors (<a href="https://xn--baw-joa.social/tags/CO2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CO2</span></a>, <a href="https://xn--baw-joa.social/tags/Ozone" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Ozone</span></a>, <a href="https://xn--baw-joa.social/tags/NO2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>NO2</span></a>) and most importantly <a href="https://xn--baw-joa.social/tags/particles" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>particles</span></a>. The two chimneys at the sides are two inlets for particle measurements: one is dried with silica beads and the other just gets unchanged ambient air. You can read more about this in this² paper. While you're at it, you can have a look at our other publications on particles, e.g. this one³.</p><p>Of course, Hopper's PARASITE payload also runs ❄️ <a href="https://xn--baw-joa.social/tags/NixOS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>NixOS</span></a>.</p><p>¹ Yup, the bad grasshopper villain from <a href="https://xn--baw-joa.social/tags/Pixar" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Pixar</span></a>'s <a href="https://xn--baw-joa.social/tags/BugsLife" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>BugsLife</span></a> <br>² <a href="https://doi.org/10.1175/JTECH-D-23-0093.1" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">doi.org/10.1175/JTECH-D-23-009</span><span class="invisible">3.1</span></a><br>³ <a href="https://doi.org/10.1175/JTECH-D-23-0078.1" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">doi.org/10.1175/JTECH-D-23-007</span><span class="invisible">8.1</span></a></p>
