panels at the site and resumed some measurements, including the independent carbon dioxide monitoring programs run by the Global Monitoring Laboratory and Scripps Institution of Oceanography, as well as other atmospheric measurements. </p> <p> Construction of a temporary road to access the observatory site is anticipated to begin in summer 2025. </p> <p class='pmarginx'> Media can contact: Theo

above sea level. The observatory is a premier atmospheric research facility that has been continuously monitoring and collecting data related to atmospheric change since the 1950's. </p> <p> The observatory protrudes through the strong marine temperature inversion layer present in the region, which separates the more polluted lower portions of the atmosphere from the much cleaner free troposphere. The undisturbed air, remote location, and minimal influences of vegetation and human activity at MLO are ideal for monitoring constituents in the atmosphere that can cause climate change. </p> <p> MLO has supported hundreds of cooperative research programs with national and international universities and government organizations. A staff of 8 operates and maintains the observatory, with offices in Hilo, Hawaii. </p> </div> <div class="col-md-5"> <div class="row no-gutters"> <div class="col-lg-3 col-6 text-center"> <a class="btn-gml-icon" href="/dv/site/index.php?stacode=mlo"> <span class="fa-stack fa-2x mt-2"> <i class="fas fa-circle fa-stack-2x"></i> <i class="fas fa-globe fa-stack-1x fa-inverse"></i> </span> <div class="icon-label">Site Info</div></a> </div> <div class="col-lg-3 col-6 text-center"> <a class="btn-gml-icon" href="/data/data.php?site=mlo"> <span class="fa-stack fa-2x mt-2"> <i class="fas fa-circle fa-stack-2x"></i> <i class="fas fa-database fa-stack-1x fa-inverse"></i> </span> <div class="icon-label">Datasets</div></a> </div> <div class="col-lg-3 col-6 text-center"> <a class="btn-gml-icon" href="/dv/iadv/?code=mlo"> <span class="fa-stack fa-2x mt-2"> <i class="fas fa-circle fa-stack-2x"></i> <i class="fas fa-chart-line fa-stack-1x fa-inverse"></i> </span> <div class="icon-label">Data Viewer</div></a> </div> <div class="col-lg-3 col-6 text-center" style="padding: 0;"> <a class="btn btn-gml-icon" href="/bin/news.php?code=mlo"> <span class="fa-stack fa-2x"> <i class="fas fa-circle fa-stack-2x"></i> <i class="fas fa-newspaper fa-stack-1x fa-inverse"></i> </span> <div class="icon-label">News</div></a> </div> </div> <div class="list-group list-group-flush list-group-condensed my-4 text-right"> <a class="list-group-item list-group-item-condensed list-group-item-action" href="/obop/mlo/aboutus/aboutus.html">About Us </a> <a class="list-group-item list-group-item-condensed list-group-item-action" href="/obop/mlo/visitingandtours/index.html"> <span class="badge badge-danger badge-pill">!</span> Visiting and Tours </a> <a class="list-group-item list-group-item-condensed list-group-item-action" href='/obop/mlo/programs/programs.html'>Programs</a> <a class="list-group-item list-group-item-condensed list-group-item-action" href="/about/stafflist.html">Personnel</a> <a class="list-group-item list-group-item-condensed list-group-item-action" href="/publications/search2.php?abstract=Mauna+Loa">Mauna Loa Publications</a> <a class="list-group-item list-group-item-condensed list-group-item-action" href="/obop/mlo/educationcenter/educationcenter.html">Outreach and Education</a> <a class="list-group-item list-group-item-condensed list-group-item-action" href="/obop/mlo/gallery/">Photo Gallery</a> </div> </div> </div> <p> Movies showing the lava flow crossing the road to the observatory: <a class='btn btn-info mb-2' href="lava_movies.html"><span class='fa-solid fa-volcano'></span> Lava Flow Movies</a> </p> <div class='text-center mt-4 mb-4'> <a class='btn btn-lg btn-primary mb-2' href="met.html"><span class='fas fa-cloud-sun-rain'></span> Current Weather</a> <a class='btn btn-lg btn-primary mb-2' href="livecam/livecam.html"><span class='fas fa-camera'></span> Live Cameras</a> </div> <hr> <div class="mt-4 mb-4"> <p> If you are interested in conducting research at one of the NOAA Baseline Observatories: <a class='btn btn-noaablue ml-4' href="https://docs.google.com/a/noaa.gov/forms/d/e/1FAIpQLSd6fGKwFLzvwuVCmKDiyETkatSX0E2i9AzU0QMcbbmJiDnZWQ/viewform">Request a New Baseline Observatory<br> Cooperative Agreement</a> </p> </div> </div> <div class="readingbox mt-3"> <div class="container"> <div class="row"> <div class="col-md-8"> <h2 class='orange'>Location</h2> <ul class='arrowlist size14'> <li>Country: United States <img src='/images/flags/smallflags/UNST0001.GIF' alt='Country Flag' style='margin-left: 10px;' width=32></li> <li>Latitude: 19.5362° North</li> <li>Longitude: 155.5763° West </li> <li>Elevation: 3397.00 masl </li> <li>Time Zone: Local Time + 10 hour(s) = UTC</li> </ul> <h2 class='orange'>Contact</h2> <ul class='arrowlist size14'> <li>Contact Name: <a href='mailto:darryl.t.kuniyuki@noaa.gov'>Darryl Kuniyuki</a></li> <li>Address: NOAA -
