+      <h2>Day Length Data</h2>
+      <p>
+        The Day Length plugin calculates data on daylight for each day of the year at any location on Earth. The
+        calculated dataset does not include the effects of clouds, land formation, and other variables that affect
+        sunlight in order to provide the underlying causes of Earth’s seasons and climate.
+      </p>
+      <h2>Simulation</h2>
+      <p>
+        An integrated simulation of the orbit of the Earth around the Sun allows for a focus on the physical
+        relationship of Earth and Sun. The data and simulation can be used to explore the amount, angle and intensity of
+        daylight that determine seasonal and climatic differences across the globe.
+      </p>
+      <h2>Solar Intensity and Sunlight Angle</h2>
+      <p>
+        Solar energy is radiant light and heat from the Sun that is important for understanding Earth’s seasons and
+        climate. The Earth’s axis and yearly orbit cause the daylight hours and solar intensity reaching the Earth to
+        vary by location.
+      </p>
+      <p>
+        Because the Earth is spherical, sunlight reaches the surface at different angles from 0° when it is at the
+        horizon (lowest solar intensity) to 90° when directly overhead (highest solar intensity). In addition, the 23°
+        tilt of the Earth’s axis further affects the angle of sunlight reaching the different latitudes of the Earth.
+      </p>
+      <p>
+        To explore actual measurement values of sunlight data for locations, we suggest visiting
+        the <Link href="https://power.larc.nasa.gov/">NASA POWER website</Link>.
