<h4><a href="/global-maps/MOD_LSTAD_M">Land Surface Temperature Anomaly</a></h4>
<p>These maps depict anomalies in land surface temperatures (LSTs); that is, how much hotter or cooler a region was compared to the long-term average. LST anomalies can indicate heat waves or cold spells.</p>

<h4><a href="/global-maps/CERES_NETFLUX_M">Net Radiation</a></h4>
<p>Net radiation is the balance between incoming and outgoing energy at the top of the atmosphere. It is the total energy available to influence climate after light and heat are reflected, absorbed, or emitted by clouds and land.</p>

<h4><a href="/global-maps/MOP_CO_M">Carbon Monoxide</a></h4>
<p>When fuels such as coal, wood, and oil burn incompletely, they produce carbon monoxide. The gas is spread by winds and circulation. These maps show monthly averages of CO in the lower atmosphere.</p>

<h4><a href="/global-maps/MODAL2_M_AER_RA">Aerosol Size</a></h4>
<p>Sea salt, volcanic ash, dust, wildfire smoke, and industrial pollution are types of airborne aerosols. Natural aerosols tend to be larger than human-made aerosols. These maps show when and where aerosols come from nature, humans, or both.</p>
