<p style="margin:0cm"><b><span style="font-size:11.0pt;font-family:"Arial",sans-serif;color:black">The Future of Heating Science</span></b><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p style="margin:0cm;text-align:justify"><span style="font-size:11.0pt;font-family:"Arial",sans-serif;color:black">We, the undersigned, strongly support the continued operation and pursuit of future research with the current and also future EISCAT Heating facilities
near Tromsø, Norway. </span><o:p></o:p></p>
<p style="margin:0cm;text-align:justify"><span style="font-size:11.0pt;font-family:"Arial",sans-serif;color:black">The Heating facilities have contributed to novel and exceptional plasma physics research for more than 40 years and have, since its transfer to
EISCAT in 1993, accounted for 20% of all EISCAT-related publications. </span><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p style="margin:0cm;text-align:justify"><span style="font-size:11.0pt;font-family:"Arial",sans-serif;color:black">The EISCAT Heater uses powerful radio waves of a few MHz frequency to perturb the ionospheric plasma. Currently, there are only two other such
facilities in the world, in Alaska and Russia. However, the EISCAT Heater is unique: it is the only heater co-located with incoherent scatter radars (ISR)!</span><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p style="margin:0cm;text-align:justify"><span style="font-size:11.0pt;font-family:"Arial",sans-serif;color:black">ISRs can observe in detail how the ionosphere behaves before, during, and after the heating process, and are thus an essential diagnostic tool
for research on wave-plasma interactions. This unique capability will soon be greatly enhanced when the new EISCAT_3D ISR becomes operational providing much higher spatial and temporal resolution. EISCAT_3D is located 50 km east of the current Heater, which
facilitates a wide range of novel experiments looking into the heated region from the side allowing for observations of its horizontal structure.</span><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p style="margin:0cm;text-align:justify"><span style="font-size:11.0pt;font-family:"Arial",sans-serif;color:black">Ionospheric heating is a crucial capability of EISCAT, and Heating-related research will be of particular importance when combined with the new
EISCAT_3D radar. It is therefore essential to continue this ground-based space research to investigate the ionosphere and upper atmosphere.</span><o:p></o:p></p>
