Dust Reduction - Intertropical Convergence Zone (ITCZ) Movement

Data Sources:

• Global Precipitation Climatology Project (GPCP) - monthly precipitation dataset from 1979-present combines observations and satellite precipitation data into 2.5°x2.5° global grids. GPCP Precipitation data provided by the NOAA/OAR/ESRL PSL, Boulder, Colorado, USA, from their Web site here

  This visualization depicts the northern trend of the Intertropical Convergence Zone (ITCZ). A horizontal black line indicates the current ITCZ centroid for the longitudinal extents of the study region, which moves with GPCP precipitation data. The northernmost extent of the ITCZ is indicated with a thin white line for each year. The bold white line represents the northernmost overall extent. The grey box represents the study region used to calculate the ITCZ centroid.
