+      ## Introduction
+      <p style={{ marginBottom: '0.4em' }}>
+      Nitrogen oxides (NOx, including NO and NO₂) are critical air pollutants linked to respiratory and cardiovascular health risks, as well as environmental impacts like smog and acid rain. NOx is primarily emitted by fossil fuel combustion in transportation, power generation, and industry. Monitoring NOx emissions is essential for air quality management, regulatory compliance, and understanding atmospheric chemistry.
+      </p>
+      <p style={{ marginBottom: '0.4em' }}>
+      The TROPESS Chemical Reanalysis Surface Total NOx Emissions Monthly 2-dimensional Product provides global, monthly gridded estimates of surface-level nitrogen oxides (NOx) emissions from anthropogenic sources. Developed using JPL’s Multi-mOdel Multi-cOnstituent Chemical (MOMO-Chem) data assimilation system, the dataset integrates satellite observations with chemical transport models to produce accurate, observation-constrained emission fields. This reanalysis uses satellite measurements, such as tropospheric NO2 column retrievals from OMI and TROPOMI, to refine NOx emissions estimates.

+    ## Data Preparation
+        These products are rigorously validated using uncertainty analysis in conjunction with independent measurements. These steps quantify the accuracies needed to make long-term trends through multi-satellite records and chemical data assimilation.

+    ## Frequently Asked Questions (FAQs)
+    <p style={{ marginBottom: '0.9em' }}>
+      <strong>What is NOx?</strong><br />
+      NOx refers to nitrogen oxides (NO and NO₂), which are harmful air pollutants mainly produced by combustion processes.
+    </p>
+    <p style={{ marginBottom: '0.9em' }}>
+      <strong>How is the data reported?</strong><br />
+      NOx concentrations are given in mg/Nm³, which means milligrams of NOx per normal cubic meter of air.
+    </p>
+    <p style={{ marginBottom: '0.9em' }}>
+      <strong>How can I use this dataset?</strong><br />
+      The data is suitable for tracking emission trends, evaluating air quality interventions, and supporting scientific research in atmospheric chemistry and climate science.
+    </p>
+    <p style={{ marginBottom: '0.9em' }}>
+      <strong>What tools are available for data analysis?</strong><br />
+      Tools such as Jupyter Notebooks (TBD), the <a href="#">VEDA visualization platform</a>, and <a href="https://search.earthdata.nasa.gov/">Earthdata Search</a> can be used to analyze this dataset.
