Data from "A Global Black Carbon Dataset of Column Concentration and Microphysical Information Derived from MISR Muti-band Observations and Mie Scattering Simulations" (2004.10.1–2020.12.31)

This dataset provides global terrestrial black carbon (BC) column concentration products derived from Multi-angle Imaging SpectroRadiometer (MISR) observations for the period 2005–2020. The derived products are archived in <b>MATLAB (.mat)</b> format and are divided into global gridded products and regionally aggregated results for nine regions (North America, South America, Europe, Africa, East Asia, Southeast Asia, South Asia, Northern Asia, and Oceania).<b>1. Global BC Products</b>Stored in <code>Global_BC_products/</code>, these files contain global grids (360×720) with various temporal aggregations:<b>Core Variables:</b><code>MASSmap</code>: BC column mass concentration (mass per unit area).<code>MASStmap</code>: BC column mass concentration (mass per grid point).<code>NUMmap</code>: BC column number concentration.<code>BCsizemap</code>: BC core particle radius.<code>Shellsizemap</code>: Sulfate shell thickness.<b>Temporal Suffixes:</b><code>_plot_world_0420</code>: Long-term mean (2004–2020).<code>_stdplot_world_0420</code>: Long-term standard deviation.<code>_world_0420</code>: Daily full-time series (multi-dimensional array).<code>_plot_world_05</code>: Annual mean for a specific year (e.g., 2005).<code>_yearmap</code>: A collection of annual averages for each year.<b>2. Regional BC Products</b>Stored in <code>Regional_BC_product/</code>, these files provide detailed data for specific regions (e.g., <code>NorthAmerica1</code>):<b>Key Fields:</b><code>masst</code>, <code>numt</code>: Mass and number concentrations per grid point.<code>BCsize</code>, <code>shellsize</code>: Microphysical dimensions.<code>BC_numt_..._mean</code>: Long-term regional average.<code>intersection_matrix_..._AAODr</code>: Refined results identifying typical pollution hotspots after applying AAOD443/865 ratio constraints.<code>NorthAmerica1_data_interp</code>: Spatial region mask.<code>daynum_count</code>: Statistics of valid observational days.<code>AAOD_ratio</code>: The AAOD 443/865 ratio used for optical filtering.<b>3. Auxiliary Datasets</b>For reproducibility, we re-host the following original datasets used in this framework:<b>MISR:</b> Level 3 global aerosol products (MIL3DAEN).<b>AERONET:</b> Field observations from the CUIABA-MIRANDA site.<b>MERRA-2:</b> Reanalysis aerosol diagnostics (M2TMNXAER).<b>4. Usage and Visualization</b>To assist users, <b>example MATLAB scripts</b> are provided in <code>Visual_Code/</code>. Key files include:<code>0Visual_Code.m</code>: Master script to load <code>.mat</code> hierarchies and generate global/regional maps.<code>Latitude.mat</code> / <code>Longitude.mat</code>: Grid coordinate files.<code>world_bdy.mat</code>: Global coastline and boundary data for plotting.<code>colormap_demo.mat</code>: Standardized color schemes for BC property visualization.<b>Contact &amp; Citation:</b> Please cite the associated ESSD paper and this Figshare DOI when using the data.<br>
